  The latest FAQ is available from the isapnptools home website as a
  text file <http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.txt>,
  a set of html files
  <http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.html.tar.gz>,
  or in the sgml source
  <http://www.roestock.demon.co.uk/isapnptools/isapnpfaq.sgml>.

  The text version is designed to be piped through less to give
  highlighting etc. If you want to strip out the control characters,
  pipe it through sed thus:

       cat isapnpfaq.txt | sed 's/^H.//g' > isapnpfaq.clean.txt

  Where ^H above is control-H. (You may need to prefix it with ^V when
  entering it on the command line).

  To see if the one on the website is newer, compare the revision with
  the revision of this document.

  Isapnptools allow you to configure the ISA PnP cards complying with
  the Plug and Play ISA Specification Version 1.0a, which may be
  obtained from ftp://ftp.microsoft.com/developr/drg/Plug-and-
  Play/Pnpspecs/ <ftp://ftp.microsoft.com/developr/drg/Plug-and-
  Play/Pnpspecs/>.

  These boards use registers instead of jumpers to set the board
  address, interrupt assignments etc (resource allocations). In
  addition, the board contains a description of the resources that need
  to be allocated, with limits on the settings allowable.

  In other words, isapnptools allow you to examine and change 'virtual
  jumpers' on the board. Note that you will need to know what other
  hardware is in your PC and what their 'jumper' settings are, including
  any devices built into the motherboard. The BIOS setup screens will
  help with this.

  The BIOS (or any other PnP configuration program such as Win95 or
  isapnptools) uses a special protocol described in the specification to
  discover all the PnP boards, and allocate the resources so that there
  are no conflicts.

  Because the BIOS rarely does the job properly, it is better to get it
  to do as little as possible, and use isapnptools to configure the
  resource settings. This is not always possible with newer BIOSes, so
  see also ``Pnpdump reports "No boards found"''.

  See the instructions in the INSTALL <INSTALL> file for the overall
  process. See the various README files for examples and specific
  details. See the FAQ too, particularly for sound cards.

  The basic idea is you run pnpdump <pnpdump.8.html> to scan your PnP
  boards and produce a skeleton configuration file. You then uncomment
  lines as required to setup the boards.

  Uncommenting lines has the same function as moving jumpers on a non-
  PnP card. Generally, for each logical device you will want to
  uncomment one each of the resources, and maybe change the value for
  the resource within the range of the comments immediately above, such
  that when you've finished there are no conflicts.

  You then run isapnp <isapnp.8.html> with the configuration file on
  each boot, and it will configure the boards like you asked. This is
  done by editing the boot up scripts to add the appropriate command.

  You also need to arrange to load the appropriate kernel driver
  modules, after configuring the boards, to allow programs to access the
  boards. In some cases the driver may already be in the kernel and you
  can just run a program to tell it about the new hardware. Again, this
  is done by adding the appropriate commands to your system boot up
  scripts.

  If you don't know how to recompile the kernel to make drivers modules
  rather than built-in etc, refer to the Kernel-HOWTO
  <http://MetaLab.unc.edu/LDP/HOWTO/Kernel-HOWTO.html>.

  In the event of difficulties, see the FAQ first for answers.

  For isapnptools release 1.19 and later, simply run pnpdump --version,
  the isapnptools release will be given.

  For earlier versions, you can run

       strings `which pnpdump` | grep '\$Id'

  which should give an output like

       $Id: isapnpfaq.sgml,v 0.12 1999/12/09 22:35:08 fox Exp $

  The isapnptools version will be the same as the pnpdump.c,v version
  for versions 1.14 and later, and one greater earlier than that. You
  can compare the version number against the CHANGES file.

  11..77..  WWhhaatt aabboouutt sseeccuurriittyy ??

  Isapnptools must be run as root, and should not be made setuid root.
  The configuration files used, such as /etc/isapnp.conf and
  /etc/isapnp.gone should be owned by, and writeable only by, root.

  This should minimize any interest in buffer overflow problems, as you
  have to be root in the first place.

  In an attempt to prevent trojans being introduced into the isapnptools
  programs, I maintain md5sums of all the files on my web site, see
  md5.txt <http://www.roestock.demon.co.uk/isapnptools/md5.txt>

  If you suspect the md5 sums have been tampered with, please tell me,
  and I can check against the originals.

  md5sum is part of the GNU textutils package.

  If you are worried about security, I suggest you maintain isapnptools
  my compiling from source. After doing an exhaustive check for trojans,
  you can then simply produce diffs of the new version against the old
  and check that.

  No. isapnp <isapnp.8.html> only configures the cards for Linux. When
  you reboot, the BIOS will restore the card's settings. Note that Win95
  will carry out the function of the BIOS (in terms of locating and
  configuring PnP boards) on PCs without a PnP BIOS.

  Having said that, you must be careful using the REG
  <isapnp.conf.5.html#REG> and POKE <isapnp.conf.5.html#POKE> keywords
  that you don't write to some register that corrupts the board resource
  data. (The resource data is often in EEPROM, and can be written to by
  suitable software to initialise it).  See also ``What does "End tag
  checksum 0xb8 (BAD)" mean (in the pnpdump output) ?''.

  Well, I quite like isapnptools as it is predictable, and doesn't make
  the kernel any bigger (but then, I may be slightly biased).

  However, you may want to check out a configuration manager for linux
  which now supports 2.0.30: CM for linux <http://lucifer.hemmet.s-
  hem.chalmers.se/~dwh>.

  You also might want to look at Tom Lees' kernel PnP suite at
  <http://www-jcr.lmh.ox.ac.uk/~pnp/>, the files are in
  <ftp.lmh.ox.ac.uk:/pub/linux/pnp/>.

  Work is underway to integrate PnP support into the kernel. See
  http://www.cs.utwente.nl/~vanrein/vha/
  <http://www.cs.utwente.nl/~vanrein/vha/>.  As this involves changing
  all the drivers, it may take a while.

  There is a GUI interface to isapnptools, see ``Is there a graphical
  interface available ?'' for more info.

  A /proc based interface has been developed for v2.2 kernels, see
  isapnp-2.2-V0.1.tgz
  <ftp://ftp.quicknet.net/Developer/Linux/Drivers/isapnp/>.

  Note that the following are ideas. Linux is a fast moving world, and
  due to the age of this document, likely to be out of date. New
  hardware is gaining support all the time.

  See the Hardware-HOWTO.

  Check your linux distribution's hardware compatibility list.  For
  example, Redhat 5.2's is at Redhat 5.2 support
  <http://www.redhat.com/support/docs/rhl/intel/rh52-hardware-
  intel-13.html>.

  Refer to the card vendor and manufacturer for Linux support
  information. If they won't support linux, tell your friends, and tell
  them you're telling your friends. Assuming you specified that the card
  was for use with Linux, you should be able to change it without too
  much trouble (having been sold a product unfit for purpose etc).

  See also ``Where can I find out more ?''

  See also the device specific sections of this FAQ below.

  A good place to find out more about PC hardware in general is the pc-
  hardware-faq, regularly posted to the newsgroups:
  comp.sys.ibm.pc.hardware.video, comp.sys.ibm.pc.hardware.comm,
  comp.sys.ibm.pc.hardware.storage, comp.sys.ibm.pc.hardware.cd-rom,
  comp.sys.ibm.pc.hardware.systems, comp.sys.ibm.pc.hardware.networking,
  comp.sys.ibm.pc.hardware.chips, comp.sys.ibm.pc.hardware.misc,
  comp.answers, news.answers.

  A good place to find out about Linux configuration etc are the HOWTOs
  and mini-HOWTOS. These can be found on MetaLab
  <http://MetaLab.unc.edu/LDP/HOWTO/> or from TSX-11
  <ftp://tsx-11.mit.edu/pub/linux/docs/HOWTO/> or try http://www.linux-
  howto.com/ <http://www.linux-howto.com/>.

  These are also normally supplied with standard Linux distributions.

  A more practical guide to using these tools (and fixing other
  configuration problems) can be found on the SuSe Linux support
  database. See /usr/doc/support-db/sdb_e/rb_isapnp.html
  <file:/usr/doc/support-db/sdb_e/rb_isapnp.html> if you've installed
  their database, or http://www.suse.de/ <http://www.suse.de/>.

  See if you can find any information/statements on the vendor websites.

  For example the soundblaster linux website
  <http://developer.soundblaster.com/linux/>.

  For PnP DOS utilities etc, see the phoenix utilites website
  <http://www.phoenix.com/products/util.html>.

  There used to be a mailing list for all pnp issues, including
  isapnptools, at pnp-list@redhat.com, but it shut down on 3-Nov-1999.
  So the answer is not that I am aware of.

  If you would like to receive release announcements for isapnptools by
  email (releases are normally announced to comp.os.linux.announce
  anyway), then send an email to isapnp-announce@roestock.demon.co.uk,

  The functionality of a card is split into many different logical
  devices for convenience. The idea is that each logical device is
  independent and has it's own driver.

  This way, the user can decide to use as much or as little of the card
  functionality as required, and also allows common drivers for many
  different boards (the drivers being written for each logical device
  function).

  So for example a soundcard will typically have at least four different
  logical devices:

  1. The basic soundcard

  2. Soundcard extensions such as wave table

  3. A game port

  4. A CD-rom port.

  The logical devices are numbered starting from 0, incrementing by 1.
  The first entry in the resource data applies to logical device 0, the
  next to logical device 1, and so on.

  Each logical device has its own set of resources ( IO
  <isapnp.conf.5.html#IO> addresses, INT
  <isapnp.conf.5.html#INT>errupts, DMA <isapnp.conf.5.html#DMA> channels
  etc) to program, and isapnp <isapnp.8.html> uses the LD
  <isapnp.conf.5.html#LD> command to select the logical device to be
  configured.

  If you get messages such as:

       bash: ./sbin/pnpdump: No such file or directory

  or

       bash: ./isapnp: No such file or directory.

  when attempting to run the precompiled binaries, then chances are you
  haven't got the required C libraries.

  To check this, change to the sbin directory and type

       ldd pnpdump
       ldd isapnp

  You should get something like

               libc.so.5 => /lib/libc.so.5

  for each one. If you get "not found" then you will have to recompile.
  Note that the precompiled binaries in my binary distributions are
  compiled for libc5. If you want binaries for glibc systems, Redhat 5.2
  on, Suse 6.0 on etc, you'll have to go elsewhere (probably to your
  distribution's web site).

  The best thing to do is to delete the binaries in the distribution and
  try to compile your own anyway.

  If you get a complaint along the lines of cannot find DPMI, then you
  need to get hold of a DPMI host software. See the FAQ on the DJGPP
  site <http://www.delorie.com/djgpp> for details (follow the path
  through Running --- Distributing).  This is most likely to occur on a
  pure DOS machine. Win95 for example includes a DPMI host.

  The free DPMI server (cwsdpmi) is normally part of the djgpp
  distribution. For example, my ISP mirrors it in the
  <ftp://ftp.demon.co.uk/pub/mirrors/coast/vendors/djgpp/v2misc/> and
  <ftp://ftp.demon.co.uk/pub/mirrors/simtelnet/gnu/djgpp/v2misc/>

  There have been reported some problems getting isapnptools 1.18 to
  compile with kernel 2.2.11. I quote Juergen Rose:

  I still played a little bit with your and with the linux sources. If I
  change in pnpdump.c and isapnp.y the order of

  #  include <linux/sched.h>
  #  include <sys/time.h>

  to

  #  include <sys/time.h>
  #  include <linux/sched.h>

  isapnptools-1.18 compiles, but with warnings. The warnings are due to the
  facts, that:

  - /usr/include/asm/processor.h is included in /usr/include/linux/sched.h
    at line 74 and needs "struct task_struct"
  - "struct task_struct" is defined in /usr/include/linux/sched.h at line
  218

  So I moved the line in /usr/include/linux/sched.h

  #include /usr/include/asm/processor.h

  below the definition of "struct task_struct". And could compile
  isapnptools-1.18 even without warnings.

  I thought this looked like kernel include file failings.

  No, or at least not easily. Issues that require addressing include

  1. Isapnptools needs to be able to get direct IO access privileges.
     (Not a problem with DOS, hence the DOS port). I suspect that this
     will require a device driver of some sort under windows NT.

  2. Some mechanism is needed to start up the device driver after isapnp
     <isapnp.8.html> has run.

  If you compiled the program using gcc2.8.0 this is very likely due to

  Recompile using gcc2.7.2.

  If you really must use gcc.2.8.x (like egcs) then you can try
  recompiling the KERNEL with the ioport.c from one of the later 2.1.xxx

  The output of pnpdump <pnpdump.8.html> should give you the examples
  you need for your hardware. If you run it with the -c (--config) flag,
  it should even show how to configure your hardware in the output. The
  output of pnpdump is supposed to be used as the input to isapnp

  Use the -di options with pnpdump <pnpdump.8.html>.

  The output dumps all the configuration registers for each device, you
  will have to interpret the results against the PnP spec, but it's
  mostly obvious.

  If you do this before running isapnp <isapnp.8.html> you can see the
  BIOS/power up defaults.

  Note that unused registers generally return all zeros. Unused DMA
  slots should return 4, though some devices erroneously return 0 (which
  is a valid used DMA channel).

  This means no boards were found.

  If you have just added a new card into an ISA bus slot, it may be
  conflicting with the readport address in your /etc/isapnp.conf file.
  You will need to check the resource assignments in your configuration
  file to make sure they don't clash with the new card.

  Try re-running pnpdump to see if it comes up with a different readport
  address, then use the new readport address in you configuration file.
  If the new card is also PnP, you may also need to copy the
  configuration instructions across too.

  Similarly, if you have changed your motherboard, it may have something
  clashing with your readport address.

  Are you sure the missing board is configured as PnP ? Many PnP boards

  There was a bug in pnpdump somewhere between isapnptools version 1.9
  and 1.15 which resulted in incorrect handling of multiple boards (the
  logical device count for each board was not reset, so only the first
  board found was correct). I suggest you upgrade to the lastest
  version.

  This means that you have no ISA PnP boards in your system. That's easy
  then, you don't need isapnptools...

  If, in fact, you think you should have some ISA PnP boards, there are
  a few possibilities:

  +o  The board is broken --- unlikely.

  +o  There is a conflict in the system resulting in no suitable READPORT
     <isapnp.conf.5.html#READPORT> address being available.

     Although this is unlikely, a faulty PnP device can give a fault
     which causes all READPORT addresses to fail. To see if this is the
     case, use the -i (--ignorecsum) flag to pnpdump <pnpdump.8.html>.
     This flag was added in version 1.18 of isapnptools.

  +o  You specified two arguments to pnpdump <pnpdump.8.html>, and the
     READPORT <isapnp.conf.5.html#READPORT> address didn't match the
     value used by the earlier PnP isolator.

     If you did this, and you used two arguments to prevent pnpdump
     <pnpdump.8.html> from resetting some device's configuration,
     upgrade to Version 1.13 of isapnptools, which will do it's own
     isolation without resetting any device's configuration, even with
     less than two arguments.

     Alternatively, if you are running the DOS version under windows 95,
     see the  <README.DOS> file in the distribution.

     If you don't care if the boards configuration is reset, just run
     pnpdump <pnpdump.8.html> with fewer arguments.
  +o  The board's PnP capability is configurable. This feature is
     provided by some boards to support legacy systems. It allows a
     board to be set to fixed address/interrupt settings, or it can be
     set to PnP mode allowing standard software reconfiguration.

     If the board has been configured to a fixed setting, pnpdump
     <pnpdump.8.html> won't find it. The thing to do is to find the (DOS
     based probably) configuration software and run it to check the
     board settings.

     If the board is this type, there are two courses of action:

     1. Use the configuration software to set the board to a suitable
        set of addresses and interrupts. This will allow the use of
        built-in kernel drivers as the board will be present at power
        up.

     2. Use the configuration software to set the board to PnP mode,
        then use isapnptools to configure the board after the kernel is
        running.

  +o  The board disappears after being configured (by the BIOS). Try the
     --reset option to pnpdump <pnpdump.8.html>.

  +o  You have a new computer, like my recent motherboard upgrade, and
     the BIOS lists the card during bootup, but isapnp <isapnp.8.html>
     can't see it.

     I've got this too, and it appears that some sort of conflict is
     occurring during the isolation sequence for the first (of two)
     boards, causing the checksum to fail for every readport address
     tried. I've added the -i (--ignorecsum) flag to pnpdump
     <pnpdump.8.html> in version 1.18 of isapnptools to allow the
     isolation process to complete in the presence of this fault.

     The fault I've seen looks like there is some sort of bus contention
     going on, with lower priority devices not dropping out like they
     should during the isolation sequence: this results in a checksum
     error on every readport address tried, because the first byte read
     on the isolation sequence looks like the logical OR of each devices
     first byte.

  +o  Another thing to try is to play with the BIOS PnP settings. I've
     had a report that setting the 'PnP aware OS' setting to YES made
     things work (this was for an ASUS TX-97 E motherboard). In my case,
     I've found that I need to set it to NO to make things work. In fact
     it's even worse than that: if I set any interrupt to non PnP,
     except IRQ10 which has my (non PnP) network card on, nothing works
     even then. And when it is working, if I ever try a full reset,
     nothing works from then on until I reboot. (My motherboard chipset
     is ACER LABS ALADDIN IV, reported by cat /proc/pci, with AMI BIOS).

  +o  Try specifying a readport address such as 0x273 manually. It may be
     that there is a PnP device at the auto selected address which is
     causing mysterious problems.

  +o  Version 1.19 and later of isapnptools adds the -D --debug-isolate
     option to pnpdump. This allows you to see the details of the
     isolation process in action. By studying the results, and the ISA
     PnP spec, you may be able to figure out what is going wrong.

  +o  It may be worth checking your hardware by seeing if windows 95/98
     can see it, if you have the option.

  +o  If the card came with DOS drivers etc, it might be worth checking
     they can access the card (running under DOS).  If so, can you run
     the DOS programs in DOSEMU and get them to still work (this will be
     difficult) ?  If so, can you trace the IO accesses to see how the
     DOS program accesses the card (V. difficult) ? If you can do all
     this, send me the patches to fix isapnptools please !

  If the word is a valid one, then it could just be that the braces are
  mismatched in your configuration file. The best solution is to strip
  out all the comments and examine what is left (the problem may then be
  obvious). You can do this easily:

       cat isapnp.conf | grep -v '^#' | sed '/^$/d' | less

  This means that attempting to read back the logical device number
  failed.  The specification is rather unclear on whether this is
  guaranteed to work, and in any event, it doesn't appear to work with
  some devices.

  There are two solutions:

  1. Get isapnp <isapnp.8.html> version 1.10 or later which supports
     VERIFYLD <isapnp.conf.5.html#VERIFYLD>.

  2. Use direct register access to select the logical device. So instead
     of configuring each logical device as normal:

       (CONFIGURE CTL009c/481377 (LD 0
       ... LD 0 settings
       (ACT Y))
       (LD 1
       ... LD 1 settings
       (ACT Y))
       (LD 2
       ... LD 2 settings
       (ACT Y))
       (LD 3
       ... LD 3 settings
       (ACT Y))
       )

  pretend they are all logical device 0, and then change the logical
  device by directly POKEing <isapnp.conf.5.html#POKE> the logical
  device register (REGister 7).

       (CONFIGURE CTL009c/481377 (LD 0
       ... LD 0 settings
       (ACT Y)
       (REG 7 (POKE 1) (PEEK)) # Set logical device 1, but no check

  It means that the resource data read from the board was corrupt, which
  in turn means that the resource data dump may be wrong. If you know
  what the card resources really are, you can still configure it with
  isapnp.

  The resource data is often stored in EEPROM, and can be written to via
  the appropriate accesses. It can be corrupted by a faulty windows 95

  This means you have attempted to CHECK <isapnp.conf.5.html#CHECK> the
  device resource allocation for conflicts using the IO range feature,
  but the device has already been activated. Either remove the check, or
  put (ACT N) before the IO allocation.

  If you rerun isapnp, this is very likely to occur. You must first
  deactivate any drivers using the board. Then, when you rerun isapnp,
  make sure there is an (ACT N) at the beginning of the device
  configuration, configure and check the settings, then (ACT Y) and the
  end to reactivate it. You can then restart the drivers for the board.

  In versions of isapnp in isapnptools-1.18 and earlier, there was a bug
  which caused this to occur anyway. A patch to fix it was produced in

  This message occurs if running kernels before the later 2.1.xxx
  series.  /proc/bus/pci/devices appears in later kernels to allow the
  PCI device information to be read. If you have disabled the proc
  filesystem, or are running an older kernel, then the isapnptools
  programs cannot check resource allocations against those assigned to
  PCI devices.

  This is unlikely to be a problem, because the resources are likely to
  be shown used in /proc/interrupts and /proc/ioports etc if a driver is
  using them. If this isn't good enough, and you still get a problem
  with resource clashes, just add the PCI resources used to the
  /etc/isapnp.gone file.

  No. You won't normally need to reboot. Only if you do something silly
  like reset the PnP hardware while a driver is trying to use it.

  The thing to do is to do all your experimenting with the programs and
  configuration files first. Only when you have the right settings, load
  the kernel drivers etc. If you want to experiment some more, unload
  the drivers first.

  This applies to 2.1.xxx and later kernels. They now include a
  configuration option CONFIG_PNP. This is intended to enable the kernel
  to configure some PnP devices, but there is little or no support in
  the kernel (2.1.131).

  If you're using isapnptools, it would probably be better to set this
  value to N, to prevent bad interactions when it does do something.

  There are lots of possibilities for this, just remember:

  1. isapnp <isapnp.8.html> must be run before the driver initialises,
     unless a separate program is available to initialise drivers later
     (eg. _s_e_t_s_e_r_i_a_l).  (See the  <README.modules> file provided with the
     distribution).

  2. The settings for the board specified to isapnp <isapnp.8.html> must
     match those of the driver for the board.

  3. You must load a driver for the card. It is not sufficient to have
     an entry in dev/.

  This means that the driver module has already been loaded or is built
  into the kernel. Try typing "cat proc/devices/" to see what devices
  are already loaded before insmodding the driver.

  This could also be due to not rebooting after rebuilding the kernel
  with module support for the required driver.

  A bug has been discovered in isapnp for Version 1.11 of isapnptools,
  relating to the setting of interrupt edges. This is unlikely to be a
  problem for most hardware because the hardware doesn't allow anything
  other that +ve edge interrupts, however, as Kevin Bowman has pointed
  out, some hardware, such as that using the Fujitsu MB86701 does allow
  the interrupt line to be programmed. In this case, try upgrading to
  Version 1.13 or later.

  /proc/interupts still lists the IRQ I am choosing as unused and the
  same for the IO ports. Does this mean the installation has failed ?

  Not necessarily. Until you load a device driver that uses them, the
  resources remain unused. You can use pnpdump -d to check the
  programming if you have a version that supports the --dumpregs option.

  If the driver you want to use can only be built into the kernel, then

  You have SCSI disks on a PnP adapter card - right ? In this case you
  must be doing a full reset of the ISA PnP hardware, which is making
  the disks disappear. Alternatively, you may have a PnP network card
  and a built-in kernel driver.

  Make sure your configuration file doesn't contain (ISOLATE
  <isapnp.conf.5.html#ISOLATE> PRESERVE).

  For the network card case, you can still do a full ISA PnP reset if
  you remove the network card driver from the kernel and use a module
  instead (and load it after running isapnp).

  This has been reported as a side effect of upgrading Slackware 3.4 to
  3.5. I'm sorry, but it must be a bug in the distribution, as upgrading
  from the isapnptools source will not do this. Please notify your
  distribution supplier as they should not stomp on user generated files
  during a package update.

  If you get the latest isapnptools, it should be possible to generate a
  good isapnp.conf file without editting, though you may need cleverer
  boot up scripts to discover the resource allocations.

  If you are updating using a non source version of isapnptools, I
  suggest you make a copy of the /etc/isapnp.conf and /etc/isapnp.gone
  files if present, just in case they get overwritten.

  You may want to regenerate the /etc/isapnp.conf file to take advantage
  of new keywords which may have been introduced. In this case run
  pnpdump -c and capture the output, then edit it in comparison to the
  previous /etc/isapnp.conf file to make the hardware configuration the
  same.

  Since version 1.16 of isapnptools, resource checking has been added.
  If your isapnp.conf file contained resource errors, these would have
  been invisible until you upgraded isapnptools. Note that due to bugs
  in the resource checking in versions prior to 1.19, resource conflicts
  may be indicated erroneously.

  Adding the line

       (CONFLICT (IO WARNING)(IRQ WARNING)(DMA WARNING)(MEM WARNING))

  near the beginning of the isapnp.conf file would allow you to restore
  the previous behaviour.

  It is very important that the resource settings you specify in the
  isapnp.conf file avoid conflict with any other devices, Plug and Play
  or otherwise. If you fail to do this, the system may fail to work
  properly, crash, or lock up.

  The easiest way to avoid conflict is to make a list of all the devices
  in your system and the resources they use.

  To help in this task, try booting the system with no PnP devices
  configured, then examine the resources the kernel is using via the
  proc filesystem (which must be mounted, obviously).

  You can also follow these instructions after configuring the PnP
  hardware and loading the appropriate driver modules to check that the
  drivers have been configured properly.

  To check the proc file system is mounted, type mount at the shell
  prompt, and somewhere in the response should be a line similar to the
  one in the example below:

       $ mount
       ...
       /proc on /proc type proc (rw)
       ...
       $

  From now on, I shall assume you have the proc filesystem is mounted on
  proc/. In addition, if you use driver modules you should ensure that
  they are all loaded so that they grab the resources they require. You
  may want to print the results obtained below:

  To see what IIOO aaddddrreesssseess are used, type "catproc/ioports/". This will
  provide a list of IO ports and the drivers that use them.

  To see what iinntteerrrruuppttss are used, type "catproc/interrupts/". This must
  be done with all your devices in use, (for example, mount a floppy
  disk so that the floppy disk interrupt is in use, and open all the
  serial ports, for example using the command "(cat < dev/ttyS1) &/").

  To see what DDMMAA cchhaannnneellss are used, type "catproc/dma/".

  Note also that some device drivers do not allocate resources unless a
  process has ooppeenneedd tthhee ddeevviiccee. This is normally the case for the
  floppy driver and serial drivers for example. This means that the
  above commands will probably not locate all the resources used by all
  the hardware, so you may still have to change some resource
  allocations to get things to work.

  Another useful command to try is

       dmesg | grep -i irq

  which will trawl through the kernel bootup messages for lines
  containing irq.  This finds resources used by kernel drivers.

  These commands will give a good idea of which resources are in use,
  but they may miss something if the device doesn't have a driver for
  example, or the BIOS has allocated the resources for some other
  purpose. So it is a good idea to check the BIOS settings when
  rebooting - particularly look for interrupt lines allocated to PCI
  devices, you may want to deallocate some of these if your PnP card
  needs a interrupt.

  Another possibility is to use the --dumpregs command to pnpdump
  <pnpdump.8.html> to see what the BIOS has allocated.
  For further information on standard motherboard resource settings and
  interrupt assignments, see the pc-hardware-faq (posted regularly to
  the comp.sys.ibm.pc.hardware.* news groups).

  The /proc filesystem only reports resources actually in use by a
  driver.

  So for example, if you configure a modem, nothing will change. If you
  then run setserial, to tell the kernel driver about the new port, you
  will see the IO ports in use in /proc/ioports, but there will still be
  no change in /proc/interrupts. It's only after you OPEN the serial
  port for the modem that the modem IRQ will be registered as in use.

  Similarly, if you configure a device which uses a kernel module
  driver, nothing will change until you load the driver module, and even
  then, not all the resources the device uses may be shown as used. Some
  resources (particularly IRQ and DMA channels) will only be shown in
  use after a program opens the device and starts using it.

  Using the PEEK <isapnp.conf.5.html#PEEK> command in an isapnp
  <isapnp.8.html> script allows the existing configuration register
  settings to be examined. Assuming that the settings don't change
  between booting Win95 and booting Linux, this script can be used to
  find the settings.

  To find out the card settings, and then to generate a script to
  reproduce them, follow these instructions:

  1. To find out what configuration registers the card has, you must
     first run pnpdump <pnpdump.8.html> with the two optional arguments.
     With pnpdump <pnpdump.8.html> from release 1.12 or later you don't
     need the additional two arguments, though a single argument may be
     useful to set the READPORT <isapnp.conf.5.html#READPORT> address.
     See  <README.DOS> for instructions on how to obtain the READPORT
     address that Win95 uses.

  2. Then examine the output to identify the number of logical devices,
     and the resources used by each one. For this it is best to pipe the
     pnpdump <pnpdump.8.html> output through grep to remove most of the
     comments thus:

       pnpdump 2 0x3bb | grep -v '# [ A-Z]' | grep -v '^#$' | grep -v '^$' > pnpdump.res

  On my system I have two cards, and pnpdump.res looks like this:

  3. Edit this to remove the duplicates, remove the (ACT

     change the resource assignment commands to (PEEK

  This shows the ethernet card (EDI0119/236861364) has a single logical
  device which uses one each IO <isapnp.conf.5.html#IO>, INT
  <isapnp.conf.5.html#INT>, and MEM <isapnp.conf.5.html#MEM> resource,
  while the PnP modem (DFX0000/1493) has two logical devices:

     a. (LD <isapnp.conf.5.html#LD> 0), which uses an IO
        <isapnp.conf.5.html#IO> resource, and an INT
        <isapnp.conf.5.html#INT> resource,

     b. (LD <isapnp.conf.5.html#LD> 1), which uses a single 8 bit DMA
        <isapnp.conf.5.html#DMA> channel.

  4. Run isapnp <isapnp.8.html> on this script, and the following output
     is obtained:

       Board 1 has Identity 13 0e 1e 37 b4 19 01 89 14:  EDI0119 Serial No 236861364 [checksum 13]
       Board 2 has Identity 6e 00 00 05 d5 00 00 d8 10:  DFX0000 Serial No 1493 [checksum 6e]
       Peek(EDI0119/236861364)[0][0x60](IO  0) is 0x0340, (3,64)
       Peek(EDI0119/236861364)[0][0x70](INT 0) is 0x0A02, (10,2)
       Peek(EDI0119/236861364)[0][0x40](MEM 0) is 0x0000000000000000, (0,0,0,0,0,0,0,0)
       Peek(DFX0000/1493)[0][0x60](IO  0) is 0x03E8, (3,232)
       Peek(DFX0000/1493)[0][0x70](INT 0) is 0x0C02, (12,2)
       Peek(DFX0000/1493)[1][0x74](DMA 0) is 0x04, (4)

  From this you can see that the modem card is configured at IO
  <isapnp.conf.5.html#IO> address 0x3E8, and uses interrupt 12.  The 2
  in the bottom half of the INT <isapnp.conf.5.html#INT> register means
  +ve edge trigger and is unlikely to ever be different. The DMA
  <isapnp.conf.5.html#DMA> channel is set to 4, which means DMA not
  used.

  Also you can see that the ethernet card is configured at IO
  <isapnp.conf.5.html#IO> address 0x340, and uses interrupt 10. The MEM
  <isapnp.conf.5.html#MEM> resource is all 0, which means it is not
  used.

  5. So to program these cards like this, use the script:

       (READPORT 0x3bb)
       (CSN 2)
       (IDENTIFY *)
       (CONFIGURE EDI0119/236861364

                       (INT 0 (IRQ 10 (MODE +E)))
                       (ACT Y)))
       (CONFIGURE DFX0000/1493
               (LD 0
                       (IO 0 (BASE 0x3e8))
                       (INT 0 (IRQ 12 (MODE +E)))
                       (ACT Y)))
       (WAITFORKEY)

  The usual source of conflicts in the sound card with something else,
  tyically the network card. This is because network cards like to be at
  addresses 0x300,0x320,0x340,etc, and sound cards use IO addresses all
  over the place, including (in my system) 0x0220-022f, 0x0330-0333,
  0x0388-038b.

  If you have a system with a network card, and then add a sound card
  later, it is quite likely that the network card is using addresses
  0x0320-033f which will be clobbered by the sound card. The solution is
  to move the network card, and in my system I have it at 0x0340-035f.

  Another common problem is to forget to configure one or more of the
  cards resources. This is particularly likely with sound cards which
  require so many. See ``How can I find out how the card is configured
  ?'' to see how you can check these.

  This means you are trying to allocate DMA1 to a PnP device, but the
  DMA resource has already been allocated to another device.

  Similar messages can occur for IO ports or interrupts.

  You need to find out what other device is using the resource, in case
  it turns out that the device you are trying to configure has already
  been configured by the BIOS, and a kernel driver has found it and is
  using it.

  To find out what is using it, look in /proc/dma, /proc/ioports,
  /proc/interrupts as appropriate, or /etc/isapnp.gone.

  If it is in use by another (different) device, then you must change
  your resource allocation.

  If is in use by the device you are trying to configure, then you
  probably don't need to configure the device using isapnptools. Simply
  make sure the kernel driver settings match those allocated by the
  BIOS.

  No. More modern BIOSes seem to configure almost all devices, so you
  don't need to run isapnptools at all. If a device is not configured
  how you want, you can just reconfigure that one. Note that if you do
  reconfigure a device, it must not have a driver running on it.  This
  means the driver must not be built into the kernel, and any driver
  modules for the device must be unloaded.

  See also ``Do I have to configure all the devices.''

  Reconfiguring a device is almost the same as configuring one.  Points
  to watch out for are:

  1. A device driver must not be using the device. This means you must
     unload the driver module. If the device driver is built into the
     kernel, and it has detected the hardware, you must not reconfigure
     the device.

  2. If you want to IO range CHECK <isapnp.conf.5.html#CHECK> the
     device, you must remember to deactivate it first. See ``What does
     "IO range check attempted while device activated" mean (from
     isapnp) ?''.

  It is not possible to use the same configuration file on multiple
  machines with these earlier versions of isapnptools.

  However, it is possible to concoct something with a few scripts etc.
  The key is to split off each board's configuration into it's own file,
  then use an empty run of isapnp with just an IDENTIFY
  <isapnp.conf.5.html#IDENTIFY> to discover which board configurations
  need to be used. Here is what I said to someone with this problem:

  I suggest you run isapnp twice (or more!):

  1. The first time, do a probe to find out which cards are present, ie,
     remove all the (CONFIGURE <isapnp.conf.5.html#CONFIGURE>...)
     sections. Use the output of the (IDENTIFY
     <isapnp.conf.5.html#IDENTIFY>) command in the isapnp script to
     choose the next script.

  2. Run the script selected by the above. Note that the second isapnp
     scripts don't need to run (ISOLATE <isapnp.conf.5.html#ISOLATE>),
     just do a (CSN <isapnp.conf.5.html#CSN> x)(IDENTIFY
     <isapnp.conf.5.html#IDENTIFY>) instead.

  If you do this, it may be advisable to fix the READPORT
  <isapnp.conf.5.html#READPORT> in all four scripts.

  Using this method, you could have an individual script for each board,
  and if you named them by the compacted ident, you could get a list of
  files to configure thus:

       BOARDS=`isapnp probe.conf | grep '^Board' | cut -c22,23,25,26,28,29,31,32,34,35,37,38,40,41,43,44,46,47`
       for board in $BOARDS
       do
               isapnp $board.conf
       done

  where probe.conf is little more than

       (READPORT 0x3bb) # or whatever
       (ISOLATE)
       (IDENTIFY *)
       (WAITFORKEY)

  Note that if you were to use this method with isapnptools version 1.12
  or later, you could skip the grep and cut by using an appropriate
  IDENTIFYFORMAT <isapnp.conf.5.html#IDENTIFYFORMAT> command.

  And each of the board scripts fit the following skeleton:

       (READPORT 0x3bb) # or whatever
       (CSN 10)         # or whatever
       (IDENTIFY *)
       (CONFIGURE ....)
       (WAITFORKEY)

  llaatteerr..

  With version 1.12 and later, CONFIGURE <isapnp.conf.5.html#CONFIGURE>
  blocks for boards not present will be skipped, so you can just have a
  single file containing the configurations for all boards in all
  systems.

  If you have machines with the same or similar setup of PnP cards, then
  this can be further optimised by having a single configuration for
  each type of card, using #1,#2,etc instead of the real serial numbers.
  Any systems with a non-standard setup could be overridden by a later
  CONFIGURE <isapnp.conf.5.html#CONFIGURE> specifying the card's full
  serial number.

       Is there a way to issue a "Reset CSN Command", as described
       in Section 4.3 (p15) of the "Plug and Play ISA Specification
       1.0a" using isapnptools?

  Sure, just poke the register using the REG <isapnp.conf.5.html#REG>
  command: after selecting a device and logical device (it doesn't
  matter which !) do

       (REG 2 (POKE 4))

  See section A.1 on page 51 also.

  This might be a good use for CSN <isapnp.conf.5.html#CSN>, as in

       (CSN 1 (LD 0 (REG 2 (POKE 4))))

  You may have to reconfigure the cards again afterwards if you want to
  fiddle with the PnP registers.

  For isapnptools up to 1.15 you can modify the Makefile to uncomment
  the line

       PNPDUMPFLAGS += -DDUMPREGS

  this will cause pnpdump will dump all the standard configuration
  registers for each board.

  For isapnptools 1.16 and later, just give the option --dumpregs to
  pnpdump to get this dump.

  Note that this dump is dumping the physical registers, and will thus
  show the settings that have been put in there by the BIOS, or some
  cards will put a default setting in. Unused registers read back as 0.

  But for example, the missing two IO resources on an AWE32 have been
  reported to show up this way.

  It is also handy to check that isapnp <isapnp.8.html> has done the
  right thing.

  The following shell script will display a list of ISA PnP boards in
  your system:

       #!/bin/bash
       cat << _EOT | isapnp -
       #(DEBUG)
       (IGNORECRC)
       (IDENTIFY-FORMAT "\"%v/%s\"\n" )
       (ISOLATE PRESERVE)
       (IDENTIFY *)
       (WAITFORKEY)
       _EOT

  on my system this gives:

       "DFX0000/1493"
       "CMI0001/16777472"

  These seem to be the cause of most problems. Just remember that for a
  card to work, the card must be accessible to the kernel (that's what
  isapnp <isapnp.8.html> is for) aanndd it must have the correct driver aanndd
  it mustn't conflict with any other devices.

  If you suspect driver problems etc, you may wish to join the sound
  mailing list at linux-sound@vger.rutgers.edu.

  The later 2.1 kernels have a new sound driver, see the documentation
  in the /usr/src/linux/Documentation/sound directory.

  Sound drivers have greatly improved with the v2.2 kernels, so you may
  find it worthwhile investigating these. Look in the kernel sources at
  Documentation/sound/Introduction, and any other documentation in there
  relevant to your card.

  See also the http://www.linux.org.uk/OSS/

  [According to Stefan Markgraf, the AWE64 suffers the same problem
  described below, where the two ports at 0xA20 and 0xE20 are not
  mentioned in the resource dump.]

  I've had some great feedback from agriffin@cpcug.org on this: (and a
  couple of corrections from Takashi Iwai <http://bahamut.mm.t.u-
  tokyo.ac.jp/~iwai/>)

  I have been able to get my SoundBlaster AWE 32 pnp configured and with
  drivers from Takashi Iwai, I now get some of the best sounds ever.
  (At least on any of the machines here.)

  I have included both the original output from pnpdump <pnpdump.8.html>
  and the conf that I use to get things working.  NNoottee that the dump
  does not detect the I/O ports at 0xA20 and 0xE20.  The manual that
  came with the card lists these ports and a note in one of the
  newsgroups show that all three of the AWE I/O ports need to be
  configured.

  Before adding the two I/O ports, the isapnp <isapnp.8.html>
  /etc/<pnpdump created file editted to activate the card> does not
  report anything unusual, but when I modprobe -a sound, syslog contains
  two lines:

               AWE32 not found
               AWE32: not detected

  and the output from  cat /dev/sndstst in this case is:

  Stefan Markgraf has reported being unable to get the 16 bit MSS
  compatibility working with this card (Jul 97), and ended up changing
  it for a AWE64.  The 8-bit Sound Blaster pro compatibility, MPU-401
  and OPL-3 functions work fine.

  There are two orientations for the CD player sound-card signals, try
  reversing the connector on the sound card if the CD player sound
  doesn't work. (From an email from kjcox@students.wisc.edu).

       After much fiddling, I finally got it to work but in the
       strangest manner.  I reversed the cable from the CD-ROM to
       the sound card 180 degrees while the computer was up and
       running.  I had to first remove the white box on the sound
       card into which the cable fits.  I tried it both ways and
       then when I put it back while the computer was running (hey,
       I got desperate) it suddenly decided to work.  It took
       awhile though to get there.

       Anyway, something to add to your FAQ.  Try removing the
       white box and reversing the cord.  You can either turn the
       box around or switch it altogether.

  This kernel message means that the sound driver couldn't get an
  interrupt from the sound card on the channel you told it to use. This
  could be due to the soundcard using a different interrupt, or more
  than one device trying to use the same interrupt.

  I get this one too. I managed to get rid of it by changing the
  preallocated ISA interrupts in the BIOS but, unfortunately, when I got
  the sound working, all the other PnP stuff stopped working. In my
  case, the sound is built into the motherboard, and there seems to be
  no way to configure it directly in the BIOS, so it's guesswork to try
  to find the interrupt allocation. If I had Win95, it might be possible
  to find it by looking at the Win95 allocation. This is where an ESCD
  BIOS interface would be useful - any takers ?

  These are the easiest PnP devices to get installed, due to the ability
  to configure devices (using _s_e_t_s_e_r_i_a_l) after the kernel has booted.
  This allows experiments to be made with the settings without having to
  reboot.

  There are a few gotchas though:

  Beware of products using phrases such as "Winmodem" or "Specially
  designed to work with Windows or Windows 95". These may well not work
  as standalone products, and require the driver provided with Windows
  to work. See also the Modem-HOWTO
  <http://www.silug.org/LDP/HOWTO/Modem-HOWTO-4.html>, some other
  Winmodem information <http://www.o2.net/~gromitkc/winmodem.html>, more
  on Winmodems
  <http://searchlinux.com/CATEGORY/HARDWARE/MODEMS/WINMODEMS/> and the
  up and coming Linux winmodem support <http://www.linmodems.org/>.  For
  a good rant, look at  <http://linuxmafia.com/~rick/faq/>.

  In a similar way some newer modems may not have the DSP code builtin,
  but rely on a program during boot to download the code into them.
  These will work in Linux if it is booted after running DOS/Windows,
  but they won't work directly after a power up into Linux.

  Watch out for PCI modems. These often don't have UARTs, and so will
  require a special driver to work with Linux. (They cannot be
  configured using isapnptools anyway, the BIOS will have done it).

  Unfortunately, a "WinModem" is only half a modem. A significant
  proportion of the modem functionality is in the Windows driver, which
  is not present when trying to use it with Linux.

  The easiest solution at present is to take it back and get a
  traditional type of modem which can be used on Unix systems. (Of
  course, if you have the ability, inclination, and required technical
  information, I'm sure there are many who would like to see a Linux
  driver for these beasts).

  PCI modems are generally winmodems. So see above.

  In any event isapnptools won't do anything for you.

  It may be that the card needs DSP code downloading onto it before
  it'll work. This can sometimes be done by booting via DOS and loadlin.

  Very slow activity can be due to interrupt clashes. When the program
  that uses the port is running, what does proc/interrupts/ say ? If the
  interrupt count is always 0 for the serial port, you probably have a
  hardware clash with two devices using the same interrupt line. Check
  your BIOS PCI settings for preallocated interrupt lines too.

  If this is the case, reassign the interrupts so that they no longer
  clash.

  Check that the modem has been configured to the correct IRQ using
  setserial. Even if you think it has. You must check that the IRQ
  reported by setserial is the same as the one you configured the modem
  to use.  Use setserial to fix the IRQ if it is wrong.

  See also ``I've configured the device, but it is really SLOW''.

  It's just something I've read in the mgetty+sendfax documentation. The
  two devices behave differently on file open, and were intended for
  dealing with modems set to auto answer. If you want to send faxes
  and/or allow dialing in, I suggest you get and install mgetty+sendfax,
  it includes an email from the writer of the serial device driver on
  why only ttySx should be used. I've seen hints that the cuax devices
  may be going in future kernels.

  The mgetty program listens to the modem and answers it manually, thus
  preventing a wasted call which would have occurred with an auto-answer
  modem and crashed computer.

  I use cu to talk to the modem. It replies with OK when I type <cr>.
  After a few transfers like this, check /proc/interrupts has increased
  by the number of characters transferred. If it hasn't, there is a
  resource clash, so try another interrupt. Note that IRQ3 and IRQ4 are
  almost guaranteed to be used by the motherboard, so don't use these
  for PnP modems.

  I've also written a program called serialmon
  <http://www.roestock.demon.co.uk/serialmon/> which allows you to
  observe the modem control lines etc.

  If the network card supports jumperless mode (fix the card's
  configuration using a DOS program that comes with it), or has jumpers
  to disable PnP mode and configure the device; if PnP settings don't
  work, the simplest thing to do is to configure the card in jumperless
  (non PnP) mode, or using the jumpers, to a fixed address and interrupt
  (I use 0x340 and IRQ10).

  In the BIOS, assign IRQ10 to legacy ISA. If you have other PnP devices
  which require configuring, remember to add the network card resources
  used to the /etc/isapnp.gone file.

  Build the network driver as a module, then load it during bootup with
  commands such as (for my NE2000 clone for example):

  # # And the network card # MODULESDIR="/usr/src/linux.`uname
  -r`.pf/modules" rm /modules ln -s $MODULESDIR /modules insmod
  $MODULESDIR/8390.o insmod $MODULESDIR/ne.o io=0x340

  This method won't require isapnp to configure the network card (in
  fact, isapnp won't be able to see it).

  If you are running a 2.1.x kernel, it is apparently possible to rescan
  the IDE interface after boot up, but only if no devices are in use on
  that controller.
