RUNNING MS-DOS 5 AS PUBLISHED BY COMPAQ.  PLEASE CONTACT YOUR LOCAL DEALER
IF YOU HAVE QUESTIONS OR NEED ASSISTANCE RUNNING YOUR APPLICATION WITH
MS-DOS 5 AS PUBLISHED BY COMPAQ.

Information in this document is subject to change without notice.

Compaq Computer Corporation shall not be liable for technical or editorial
errors or omissions made herein; nor for incidental or consequential
damages resulting from the furnishing, performance, or use of this
material.

companies.

1. Aboveboard 286 and Aboveboard Plus Installation Programs

CAUTION: The Intel Aboveboard installation program tests memory in a way
that corrupts extended memory.

Before using Intel's Aboveboard installation program, make sure you
haven't loaded software such as CEMM, CACHE, VDISK, SMARTDRiVe or
RAMDRIVE that is using extended memory.

2. AUTORUN.EXE

If you can't use Mountain Network Solutions AUTORUN.EXE, a tape-drive
backup program, contact your vendor for an upgrade.

3. CodeView

CAUTION: Using versions 3.0 to 3.13 of the CodeView CV.EXE file may
cause the loss of data if your system has a 80386 memory manager (such
as CEMM.EXE) and device drivers or programs that use extended memory.

To start CodeView versions 3.0 to 3.13 safely, use the CV.COM file
included with MS-DOS 5.0. Copy the CV.COM file from the distribution
disks to the directory that contains your CV.EXE file. Then, type the
following to start CodeView:

	CV
	or
	CV.COM

If you start CodeView by using a batch file or program item in a shell
(such as MS-DOS Shell), change the batch file or program item so that it
specifies the CV.COM instead of the CV.EXE file.

Make sure you use a HIMEM.EXE driver version 2.66 or later (or HIMEM.SYS
driver version 2.77 or later) with CodeView. Otherwise, the CV.COM file
will not prevent data loss. COMPAQ MS-DOS 5.0 includes HIMEM.EXE version
2.66.

This problem has been fixed in CodeView version 3.14. Call Microsoft
Customer Service to get this version.

4. Easel 6.0

Interactive Images Easel 6.0 is incompatible with the DOS=HIGH and the
CEMM driver. Contact your vendor for an update.

5. Fastback

If you run MS-DOS 5.0 in the high memory area, you must use the LOADFIX
command before running Fifth Generation Systems Fastback or the Fastback
installation program. Type the following:

	LOADFIX fb.exe
	or
	LOADFIX fbinstal.exe

For information about the LOADFIX command, see Chapter 5 of the COMPAQ
MS-DOS Version 5 Reference Guide.

6. GeoWorks

If you cannot run GeoWorks (PC/GEOS) after installing MS-DOS 5.0, use the
SETVER command to report version number 4.01 to the GEOS.EXE file.  Do not
run the installation program for GeoWorks Ensemble when MS-DOS Shell Task
Swapper is active. Use the Exclusive Tasking option when running GeoWorks
Ensemble with Windows, and use the Prevent Program Switch option when
running it with MS-DOS Shell Task Swapper.

7. Keyboard Conflicts

Some software packages do not support the extended ROM BIOS for 101/102-
key keyboards.  These include Lotus Metro, Lotus Express, IBM Displaywrite
III, Borland Turbo Lightning, and Micro Logic Tornado 1.8. If you can't
use your keyboard after starting an application, restart your computer,
and add the following line to your CONFIG.SYS file:

	switches=/k

If you are using ANSI.SYS, also add a /k switch to the DEVICE=ANSI.SYS
command in your CONFIG.SYS file.

8. Lotus 1-2-3 (3.0 or Later)

If you run Lotus 1-2-3 3.0 with Task Swapper in MS-DOS Shell, set the
XMS Memory KB Required option in the Advanced dialog box to 384.

For more information about specifying advanced properties, see Chapter 5
of the COMPAQ Using MS-DOS Shell guide.

If you run Lotus 1-2-3 3.0 or later and load device drivers or memory-
resident programs into the upper memory area, use the RAM switch with
the DEVICE=CEMM.EXE statement in your CONFIG.SYS file.

9. Manifest

Version 1.0 of Quarterdeck Manifest is incompatible with MS-DOS 5.0.
Contact your vendor for an upgrade.

10. Paintbrush 2.0

If you have an EGA monitor and want to run Microsoft or ZSoft Paintbrush
2.0, you must remove the DEVICE=EGA.SYS command from your CONFIG.SYS file.
After removing the command, you may have difficulty with screen swapping
when using Task Swapper in MS-DOS Shell.

11. PC-Kwik Disk Accelerator

Do not load versions of Multisoft PC-Kwik Disk Accelerator earlier than
2.0 into the upper memory area.

12. Pklite

Do not use Pklite to pack device drivers.

If you have a PC-Kwik cache on your system, and you can't run a packed
program, do one of the following:
	* Use the LOADFIX command to start the program.
	* Run MS-DOS 5.0 in conventional memory.
	* Run a version of the program that was not packed with Pklite.
	* Disable asynchronous reads on the PC-Kwik cache.

For information about the LOADFIX command, see Chapter 5 of the COMPAQ
MS-DOS Version 5 Reference Guide.

13. ProKey and MS-DOS Editor/QBasic

Some versions of RoseSoft ProKey are incompatible with MS-DOS Editor and
QBasic.

14. Sidekick 2.0

If you are running MS-DOS 5.0 in the high memory area, use the following
LOADFIX command to start Borland Sidekick 2.0:

	LOADFIX sk2.exe

For information about the LOADFIX command, see Chapter 5 of the COMPAQ
MS-DOS Version 5 Reference Guide.

15. Soft-ICE

When using Nu-Mega Soft-ICE, load it before loading other drivers.
Otherwise, you may lose data stored in extended memory by drivers such
as CACHE or VDISK.

16. Software Carousel

Software Carousel 5.0 is incompatible with MS-DOS 5.0.

If you installed HIMEMSLS.SYS, remove the DEVICE=HIMEMSLS.SYS command
from your CONFIG.SYS after running Setup.

To use DOSKEY, load it after loading Software Carousel into memory.

17. Task Swapper and Asynchronous I/O

Some programs that perform asynchronous communications are incompatible
with MS-DOS Shell Task Swapper. Terminal-emulation software (such as
SmartCom and Procomm Plus) and server/client software (such as Laplink and
Blast) are asynchronous communications programs. If you can't use an
asynchronous program, contact your vendor for more information.

18. Turbo Debugger 386

The Borland Turbo Debugger 386 is configuration dependent and must be
reinstalled after you upgrade to MS-DOS 5.0.

19. Ventura Publisher

If you can't start Ventura Publisher, make sure your Ventura Publisher
directory is within the first 70 characters of the PATH command in your
AUTOEXEC.BAT file.

20. WordPerfect WPINFO.EXE 5.1

Some versions of WordPerfect WPINFO.EXE are incompatible with MS-DOS
5.0. Contact your vendor for more information.

21. WordPerfect Office 3.0

Some versions of WordPerfect Office 3.0 are incompatible with MS-DOS
5.0. Contact your vendor for more information.

22. XTreeNet

To use XTreeNet with MS-DOS Shell Task Swapper, select the Prevent
Program Switch option in the MS-DOS Shell Advanced dialog box. For more
information about specifying advanced properties, see Chapter 5 of the
COMPAQ Using MS-DOS Shell guide.

23. 386MAX Version 5.11 or Earlier

If you have software the requires the SETVER facility and you are using
386LOAD.COM or MAXHI.COM from Qualitas to load  this software, then you
must set the same version for the 386LOAD or MAXHI program. This version
number will be reported to all programs loaded by 386LOAD or MAXHI.

MAXHI from 386MAX versions before 5.0 are incompatible with MS-DOS 5.0.
