LILO INSTALLATION

LILO (the Linux Loader) is the program that allows booting Linux directly from
the hard drive. To install, you make a new LILO configuration file by creating
a new header and then adding at least one bootable partition to the file. Once
you've done this, you can select the install option. Alternately, if you 
already have an /etc/lilo.conf, you may reinstall using that. If you make a
mistake, just select (1) to start over.

1 -- Start LILO configuration with a new LILO header
2 -- Add a Linux partition to the LILO config file
3 -- Add an OS/2 partition to the LILO config file
4 -- Add a DOS partition to the LILO config file
5 -- Install LILO
6 -- Reinstall LILO using the existing lilo.conf
7 -- Skip LILO installation and exit this menu
8 -- View your current /etc/lilo.conf
9 -- Read the Linux Loader HELP file

OPTIONAL append="" LINE

Some systems might require extra parameters to be passed to the kernel in order
to boot. An example would be the hd=cyl,hds,secs needed with some SCSI systems
and some machines with IBM motherboards. If you needed to pass parameters to the
kernel when you booted the Slackware bootkernel disk, you'll probably want to
enter the same ones here. 

Most systems won't require any extra parameters. If you don't need any, just
hit ENTER to continue.

SELECT LILO TARGET LOCATION

LILO can be installed to a variety of places: 
 1. The Master Boot Record of your first hard drive
 2. The superblock of your root Linux partition (which could then
    be made the bootable partition with fdisk)
 3. A formatted floppy disk

If you're using a boot system such as OS/2's Boot Manager, you should install
LILO on the superblock of your root Linux partition.

CHOOSE LILO DELAY

How long would you like LILO to wait for you to hit left-shift to 
get a prompt after rebooting? If you let LILO time out, it will boot
the first OS in the configuration file by default.

1 -- None, don't wait at all - boot straight into the first OS
2 -- 5 seconds
3 -- 30 seconds
4 -- Present a prompt and wait until a choice is made without timing out
