1. README CONVENTIONS

=
======== If you have questions about procedures or commands mentioned in this file, you will probably find answers in the Microsoft MS-DOS User's Guide and Reference. The following paragraphs describe frequently mentioned topics that the guide covers in more detail.

Many sections of the readme discuss changing your CONFIG.SYS file. For detailed information about modifying a CONFIG.SYS file, see Chapter 11 of the MS-DOS User's Guide and Reference.

The readme often refers to DEVICE commands in your CONFIG.SYS file. For example, one section recommends &quot;adding a /machine:1 switch to the DEVICE=HIMEM.SYS command in your CONFIG.SYS file.&quot; These DEVICE= statements indicate the type of command in the CONFIG.SYS file. You need to modify these statements to reflect the configuration of your system. For more information, see the DEVICE command in Chapter 14 of the MS-DOS User's Guide and Reference.

The readme sometimes asks you to use the EXPAND command to copy files from the distribution disks to your hard disk. See Chapter 14 of the MS-DOS User's Guide and Reference for more information about using the EXPAND command.

2. NOTES ON SETUP

=
====

2.1 Priam and Everex Disk-Partitioning Software --- For information about Priam and Everex, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of Getting Started.

2.2 SyQuest Removable Hard Disk --- For information about SyQuest, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

2.3 Bernoulli Drive --- If Setup refers you to this section, contact Iomega before you install MS-DOS 5.0 to get information about an updated RCD.SYS device driver.

2.4 Disk Manager

For information about Disk Manager, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

2.5 SpeedStor and Volume Expansion -- If you have a SpeedStor partition on your computer, Setup probably referred you to this section for one of the following reasons:

for the device driver that supports your SpeedStor partition. If this is the case, add the command line to your CONFIG.SYS file, restart your computer, and run Setup. For more information about adding the command line to your CONFIG.SYS file, see your SpeedStor documentation.
 * Setup could not find in your CONFIG.SYS file a command

If this is the case, carry out the following procedure: 1. Use the EXPAND command to expand and copy the SSTOR.SYS file to your hard disk. See the PACKING.LST file on Setup disk 1 for the location of the file and for instructions on how to expand and copy it to your hard drive.
 * Your CONFIG.SYS file has a DEVICE=HARDRIVE.SYS line in it.

2. Replace the DEVICE=HARDRIVE.SYS file with a DEVICE=SSTOR.SYS command.

3. Type the following: setup /u

If you have a Novell or Xenix partition, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

If your system is an IBM PS/2 or has MicroChannel architecture, contact your software vendor for disk- partitioning software that is compatible with MS-DOS 5.0.

2.6 Novell Partitions - For information about Novell Partitions, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

2.8 Columbia Data Products Device Driver

If you use a Columbia Data Products device driver, do the following:

1. Remove the DEVICE=SSTBIOS.SYS and DEVICE=SSTDRIVE.SYS commands from your CONFIG.SYS file before running Setup. 2. Restart your system. 3. Run Setup. 4. Reinstall the device drivers by returning the DEVICE= commands to your CONFIG.SYS file and restarting your system.

2.9 Incompatible Primary DOS Partition -- If Setup referred you to this section, and no other section in part 2 of this README.TXT file is relevant to your system, you have a partition that is incompatible with MS- DOS 5.0. You must delete the partition from your hard disk. See the section &quot;Setup detected a problem with your primary DOS partition&quot; in Chapter 3 of &quot;Getting Started.&quot; Make sure you back up the files on your hard drive before deleting your partition.

2.10 WYSE Partition --- If you have partitions created by WYSE DOS 2.11 or 3.1, you must delete them from your hard disk before running Setup. See the section &quot;Setup detected a problem with your primary DOS partition&quot; in Chapter 3 of &quot;Getting Started.&quot; Make sure you back up the files on your hard drive before deleting your partition.

2.11 286 Accelerator Card - If your system includes a 286 accelerator card, Setup may not be able to determine the amount of extended memory you have and may incorrectly install MS-DOS 5.0. If this occurs, disable the card before running Setup. If you can't disable the card, install MS-DOS 5.0 manually. Use the procedure in the &quot;Priam and Everex&quot; section of &quot;Setup display the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Start.&quot;

2.12 Bernoulli Cache

For information about Bernoulli Cache, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

2.13 AT&T 6300 Computer --- If you use an AT&T 6300 computer and your ROM BIOS is version 1.20 or earlier, contact your vendor for a ROM BIOS upgrade. The ROM BIOS version number is displayed when you start your computer.

2.14 Western Digital SCSI Hard-Disk Controller -- If you are using a Western Digital WD 7000 FASST or AT/XT SCSI controller with hard-disk ROM version 3.35 or earlier, contact Columbia Data Products Customer Services for an upgrade before installing Windows and MS-DOS 5.0. The ROM version number is displayed when you start your computer.

2.15 Machine-Specific HIMEM.SYS Switches

For HIMEM.SYS /machine switch values, see &quot;You receive the 'Missing HIMEM.SYS' message&quot; in Chapter 4 of &quot;Getting Started.&quot;

2.16 Toshiba with a Hard RAM Disk - These instructions apply to Toshiba models T1200, T1600, T1200XE and T1000LE.

To use the hard RAM disk, do the following before installing MS-DOS 5.0: 1. Back up your hard RAM disk. 2. Using the Toshiba Setup program, delete the hard RAM disk by allocating zero kilobytes to it. All data on    the hard RAM disk will be lost. 3. Restart your system. 4. Install Windows and MS-DOS. 5. Use the Toshiba Setup program to reinstall the hard RAM disk. 6. Run FDISK, change to drive 2, and create a primary DOS partition. Quit FDISK. 7. Use the FORMAT command to format drive D.

2.17 Unix And Xenix Partitions -- If you have a Novell or Xenix partition, see the section &quot;Setup displays the 'Incompatible hard disk or device driver' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

2.18 Apricot XEN-S Computer --- To install Windows and MS-DOS on an Apricot XEN-S computer: 1. Remove the DEVICE=AEMM386.SYS command from your CONFIG.SYS file. 2. Restart your system. 3. Run Setup. 4. Put the DEVICE=AEMM386.SYS command back in your CONFIG.SYS file and restart your system.

2.19 4DOS - Setup replaces the SHELL command in your CONFIG.SYS file with one that invokes COMMAND.COM. To recover your 4DOS SHELL command, retrieve it from the original CONFIG.SYS file, which is saved as CONFIG.DAT on your Uninstall disk.

If external DOS utilities display messages that refer to error numbers, contact JP Software for an upgrade.

2.20 LapLink - If you use Traveling Software LapLink, disable the LapLink device driver before you install Windows and MS-DOS. The driver conflicts with the Setup program. Once you install Windows and MS-DOS, re-enable the LapLink driver.

2.21 Stacker

If you are using Stacker data-compression software on your computer, begin by determining which drives are compressed and which are uncompressed.

To determine which drives are compressed and which are uncompressed


 * Type the following at the command prompt:

[drive]:\stacker\swapmap

For the [drive] parameter, type the letter of the drive that contains your Stacker directory.

If drive C was drive C at boot time, carry out Procedure 1.

Otherwise, the drive that was C at boot time is the uncompressed drive. The drive that is now C is compressed. Carry out Procedure 2.

Procedure 1

To set up Windows and MS-DOS

1. Type the following at the command prompt:

a:setup

2. When the &quot;A disk-compression program is in use&quot; screen appears, choose Continue Setup.

3. Follow the instructions on your screen.

Procedure 2

You need to determine whether there is enough disk space on your uncompressed drive to set up MS-DOS 5.0

To determine whether there is enough disk space


 * Type the following at the command prompt:

chkdsk [drive]:

For the [drive] parameter, type letter of the uncompressed drive.

Information about your hard disk appears. If the bytes available on disk is more than 3,000,000, carry out Procedure 1. Otherwise, carry out Procedure 3.

Procedure 3

To set up Windows and MS-DOS on a computer that has Stacker installed

1. Quit Setup if you have not already done so.

2. Set up MS-DOS on floppy disks by typing the following at the command prompt:

a:setup /f

Follow the instructions on your screen.

NOTE If you run Setup from drive B and have 1.44 MB Setup disks, see section 2.27 of the README.TXT file to set up MS-DOS on floppy disks.

3. Restart your computer from the hard disk by removing disks from all floppy disk drives, and restarting your computer by   pressing CTRL+ALT+DEL.

4. To determine the path of COMMAND.COM file, type the following at the command prompt:

set

A list of environment variables appears on your screen.

The line that begins with COMPSPEC= indicates the location of the COMMAND.COM file. For example, the following indicates that the COMMAND.COM file is   in the DOS directory:

COMSPEC=C:\DOS\COMMAND.COM

5. Type the following at the command prompt:

c:\stacker\swapmap

The drive that was C at boot time is the uncompressed drive. The drive that is now C is the compressed drive.

6. Create an OLDDOS directory by typing the following at    the command prompt:

md c:\olddos

7. Copy your old DOS files to the OLDDOS directory. For example, if your files are in C:\DOS, type the following at the command prompt:

copy c:\dos\*.* c:\olddos

8. Delete your original DOS files from your DOS directory. For example, if your original files are in the DOS directory on   drive C, type the following at the command prompt:

del c:\dos\*.*

9. Copy all files from the Startup/Support disk to the directory that contained your original DOS files.

For example, if the Startup/Support disk is in drive A, and you want to copy the files to the DOS directory on drive C, type the following:

copy a:*.* c:\dos

10. If the COMSPEC variable indicates that the COMMAND.COM file is in a directory other than the one your original DOS files were in, copy the COMMAND.COM file to the directory the COMSPEC variable specifies.

11. Copy the COMMAND.COM file to the DOS directory on   the uncompressed drive. (Refer to Step 5 to determine   which drive uncompressed.) For example, if the Startup/ Support disk is in drive A and the DOS directory is   on the uncompressed drive E, type the following at    the command prompt:

copy a:command.com e:\dos

12. Insert the Help/BASIC/Edit/Utility disk in drive A,   and copy all the files from it to your DOS directory. Then insert the Supplemental disk in drive A, and copy all the files from it to your DOS directory on drive C.

13. On the uncompressed drive, update any drivers in your CONFIG.SYS file that load before the STACKER.COM file.

Typically, these files are located in the DOS directory on the uncompressed drive. For example, if the DOS directory contains the SETVER.EXE, EMM386.EXE, and HIMEM.SYS files, copy these files from your floppy disks to the DOS directory on the uncompressed drive. To determine the location of   the device driver files on the Startup/Support, Help/BASIC/Edit/Utility, and Supplemental disks, open the PACKING.LST file on Setup Disk 1 by using any text editor.

If a driver you need is not located on one of   these disks, expand and copy the driver from the Setup disks. To determine the location of the driver you need, open the PACKING.LST file on Setup Disk 1 by using any text editor. The PACKING.LST file also contains instructions on how to expand the compressed files on the Setup disks.

Note: Do not update the SMARTDRV.EXE or SMARTDRV.SYS files. Setup will update these file for you.

14. Copy the CHKDSK.EXE file from the DOS directory on   drive C to the DOS directory on your uncompressed drive.

15. Insert the Startup/Support disk in drive A, and restart your computer by pressing CTRL+ALT+DEL. Then type the following at the command prompt:

sys a: c:

16. Remove disks from all floppy disk drives, and restart your computer by pressing CTRL+ALT+DEL. If Stacker prompts you to update the COMMAND.COM file, choose Yes.

17. To make sure you can access your hard disk, type the following at the command prompt:

c:   dir

18. Insert the Startup/Support disk in drive A, and type the following at the command prompt:

a:   sys a: c:

19. Repeat step 16.

Note: After you have set up Windows and know your system is   working correctly, you might want to delete the DOS files in    your OLDDOS directory.

20. Before setting up Windows, read the following information.

If you are using Stacker to compress your hard disk, there are certain steps you need to take before setting up Windows.

set up the swap file on the uncompressed drive. When setting up Stacker, you can leave at least 1 megabyte (MB) of disk space uncompressed for storing system files. To  leave enough space for the swap file, it is recommended that you allocate as uncompressed disk space twice the amount of your system memory. For example, if your system has 4 MB of memory, you should leave at least 8 MB  of disk space uncompressed. For more information about swap files, see &quot;Working with Windows Swap Files&quot; in Chapter 14, &quot;Optimizing Windows,&quot; in the &quot;Microsoft Windows User's Guide.&quot;
 * If you want to use a swap file with Windows, you must

If Stacker is already set up on your computer and there is not enough uncompressed disk space for a swap file, you can run the STAC utility provided with Stacker to increase the amount of uncompressed disk space. For more information, see your Stacker documentation.

Stacker 2.0 or later, choose the Custom Setup option when you run Setup. When Setup prompts you, don't choose to let Setup modify your CONFIG.SYS and AUTOEXEC.BAT files. Modify these files yourself after Setup is complete, by carrying out the following steps:
 * If you upgraded from an earlier version of Stacker to

* In your AUTOEXEC.BAT, add Windows to your path.

* Copy the HIMEM.SYS and EMM386.EXE files to your uncompressed drive, unless you use a different memory manager, such as QEMM-386.

* Add DEVICE commands for HIMEM.SYS and EMM386.EXE to    your CONFIG.SYS, unless you use a different memory manager such as QEMM-386. The command lines that load these drivers should appear before the command that loads STACKER.COM.

* Make sure a copy of SMARTDRV.EXE is on the uncompressed drive. In your CONFIG.SYS file, the SMARTDRV.EXE command line should include the &quot;/double_buffer&quot; switch and should be the path of the file at boot time. For example, if SMARTDRV.EXE is in the root directory at boot time, you would include the following command in your CONFIG.SYS:

DEVICE=C:\SMARTDRV.EXE DOUBLE_BUFFER

SMARTDRV.EXE should be loaded before STACKER.COM in the CONFIG.SYS file.

* In the AUTOEXEC.BAT file, the SMARTDRV.EXE command line should be the path of the file after disk drives are swapped.

upgrade from Stacker version 1.1, choose the Express Setup option when you are prompted. Setup will modify your CONFIG.SYS and AUTOEXEC.BAT files for you. When Setup is finished making the modifications, it displays a message at the end of the Windows portion of Setup that notifies you of the modifications that have been made. If you have used Stacker to  swap your startup drive, when you restart your system Stacker will ask whether you want to update to the new version of the CONFIG.SYS or AUTOEXEC.BAT file. Choose Yes.
 * If you are using Stacker version 2.0 or later, but didn't

need to modify your CONFIG.SYS and AUTOEXEC.BAT files yourself, using the CONFIG.WIN and AUTOEXEC.WIN files that Setup generates. For information about using these files, see &quot;Modifying Your CONFIG.SYS and AUTOEXEC.BAT Files Yourself,&quot; following this topic.
 * If you are using a version of Stacker earlier than 2.0, you

the command prompt to set up Windows:
 * After you have set up MS-DOS manually, type the following at

a:setup /w

Modifying Your CONFIG.SYS and AUTOEXEC.BAT Files Yourself -

If Setup cannot modify your startup files, Setup writes proposed changes to the CONFIG.WIN and AUTOEXEC.WIN. (These files may also be named CONFIG.00x and AUTOEXEC.00x if CONFIG.WIN and AUTOEXEC.WIN already exist). In this case, you must either move the HIMEM.SYS, SMARTDRV.EXE, and EMM386.EXE files to a drive that is available when you start your computer, or use a text editor to modify your CONFIG.SYS or AUTOEXEC.BAT file so that any references to HIMEM.SYS, SMARTDRV.EXE, and EMM386.EXE appear after the DEVICE command that loads the drivers for your disk drives. Refer to the CONFIG.WIN and AUTOEXEC.WIN files for the proposed changes.

NOTE Setup may also create AUTOEXEC.OLD and CONFIG.OLD files if it cannot modify your startup files. (These files may also be named AUTOEXEC.00x and CONFIG.00x if AUTOEXEC.OLD and CONFIG.OLD already exist.) If Setup creates AUTOEXEC.OLD or CONFIG.OLD files, note the reason that it does so. Then merge the CONFIG.OLD and CONFIG.WIN files with the CONFIG.SYS file, and the AUTOEXEC.OLD and AUTOEXEC.WIN files with the AUTOEXEC.BAT file.

NOTE If you use another memory manager such as QEMM-386, do not copy HIMEM.SYS or EMM386.EXE to a drive that is available when you start your computer, and do not add commands for these files to your AUTOEXEC.BAT or CONFIG.SYS file. These files should already include the correct command lines for your memory manager.

2.22 Dell DOS 3.30 -- Some Dell DOS 3.30 installations were done with a utility called AFORMAT, which creates and formats multiple 32 MB partitions. These extended partitions become invisible with Windows an dMS-DOS unless you run a utility called FIXPART before or after installing Windows and MS-DOS. Contact Dell to obtain the FIXPART utility.

2.23 Tandy with ROM DOS --- Contact your hardware manufacturer for information about upgrading a Tandy computer with ROM DOS to MS-DOS 5.0. This applies to the following models: 1000HX, 1000SL, 1000SL2, 1000TL, 1000TL2, 1000TL3, 2500XL, 2500XL2.

2.25 SpeedStor BootAll option - If you have SpeedStor BootAll, see the section &quot;Setup displays the 'Incompatible Partition' screen&quot; in Chapter 3 of &quot;Getting Started.&quot;

2.26 Setup switches for corporate administrators

The following Setup switches can be used when installing Windows and MS-DOS:

/G             Does not create the Uninstall Disk, does not ask if the user is on a network, and does not offer the hard disk backup option. /G /H:filespec Runs the MS-DOS portion of Setup in Batch-mode and uses the default Setup options unless. Also runs the Windows portion of Setup according to               FILESPEC file. /J             Does not ask if the user is on a network and does not offer the hard disk backup option. /W             Installs Windows only. /A             Expands and copies files on Setup disks to                a network server. To run Windows and MS-DOS Setup, type &quot;dwsetup&quot; at the command prompt. Note: Typing &quot;setup&quot; at the command prompt will run Windows-only Setup.

2.27 Setting up MS-DOS on floppy disks if your Setup disks are 1.44 MB but your drive A is 1.2 MB -- To make a setup of floppy disk, carry out the following procedure:

1   Insert Setup disk 1 in drive B and a formatted floppy disk in     A. 2    Type the following at the command prompt: b:setup /f /m Specify drive A for the Startup/Support disk. 3   Insert Setup disk 1 in drive B, and type the following at the command prompt: b:setup /f Follow the instructions on your screen. Use the disk you created in step 2 as your boot disk. Use the disks you created in step 3 when you want to use an MS-DOS command.

2.28 Your non-Windows application runs out of memory after Setup

If you are running a non-Windows application that uses a lot of memory, and it runs out of memory from the command line, try the following:

information, see &quot;Using the SMARTDrive Command Line&quot; in Chapter 14, Optimizing Windows, in the &quot;Microsoft Windows User's Guide.&quot;
 * Lower the amount of memory that SMARTDrive uses. For more

see Chapter 7, &quot;Non-Windows Applications,&quot; in the &quot;Microsoft Windows User's Guide.
 * Run the non-Windows application from Windows. For more information,

2.29 MS-DOS Shell doesn't work correctly on a computer with an 8514 display or ATI Ultra card --- If the MS-DOS Shell doesn't work correctly after installing Windows and MS-DOS and your system has an 8514 display or ATI Ultra card, carry out the following procedure:

1   Run Setup again. 2   Choose the Install MS-DOS only option. 3   Change the Video Type to 8514. 4   Complete Setup.

2.30 SuperStor with DR-DOS -- If you use SuperStor on a computer with DR-DOS, do not use the SSTORDRV.SYS driver with MS-DOS 5.0. This driver has not been tested with MS-DOS 5.0. Instead, carry out the following procedure:

1   Back up all of your data files onto floppy disks. 2   Install MS-DOS onto floppy disks by typing the following at the command prompt:

a:setup /f

If you have 1.44 MB Setup disks for drive B, see section of 2.27.

3   Reformat your hard drive and transfer your system files by     inserting the Startup/Support disk in drive A, and typing the following at the command prompt:

format c: /s

4   Run Setup to install Windows and MS-DOS. 5   Restore your data files to the hard drive.

2.31 You receive the &quot;Unable to control the A20 line&quot; message - If you receive this message during Setup, carry out Procedure 1. If you receive this message after Setup, your computer is an 80386 or 80486, and you are running QEMM-388, carry out Procedure 2. If you receive this message after Setup, your computer is an 80386 or 80486, and you are trying to run Windows 3.0, carry out Procedure 3.

Procedure 1

1   Quit Setup if you have not already done so. 2   Run Setup again. 3   Choose the Install MS-DOS only option. 4   When you restart your computer, observe whether this message appears on your screen.

If you receive this message again, you need to add a /MACHINE switch to the command that loads the HIMEM.SYS file in your CONFIG.SYS file. See the table in &quot;You receive the 'Missing HIMEM.SYS' message&quot; in Chapter 4, &quot;Troubleshooting During System Startup,&quot; in &quot;Getting Started to determine what switch to use. After you have added the switch to your CONFIG.SYS file, restart your computer by pressing CTRL+ALT+DEL.

5   Run Setup again. 6   Choose the Install Windows only option.

Procedure 2

1   Open your CONFIG.SYS file with any text editor. 2   Add the following line to the end of the file:

switches=/w 3   Save the file, and restart your computer by pressing CTRL+ALT+DEL. 4   Run Windows.

Procedure 3

the root directory of drive C. See the PACKING.LST file on Setup disk 1 for the location of the WINA20.386 and for instructions on how to expand and copy the file.
 * Expand the WINA20.386 file from the Setup disks and copy it to

2.32 Bootsafe - If you are running Bootsafe, you may experience problems while running Setup. Carry out the following procedure:

1   Open your AUTOEXEC.BAT with any text editor. 2   Type &quot;REM&quot; and a space in front of the line that loads Bootsafe. For example, the line might look something like this:

rem c:\cpav\bootsafe

3   Save the file, and restart your computer by pressing CTRL+ALT+DEL. 4   Run Setup again.

3. NOTES ON MEMORY MANAGEMENT

=
================

3.1 386MAX (5.11 or Earlier)

If you have used the SETVER command to report a different version number to a program you are loading into the upper memory area with 386LOAD.COM or MAXHI.COM, also use the SETVER command to report that number to 386LOAD.COM or MAXHI.COM. For information about the SETVER command, see Chapter 14 of the MS-DOS User's Guide and Reference.

The new version number is reported to all programs loaded by 386LOAD.COM and MAXHI.COM.

MAXHI.COM programs supplied with versions of 386MAX earlier than 5.0 are incompatible with MS-DOS 5.0.

3.2 All Computers Inc. Expanded-Memory Driver (ALLEMM4.SYS) --- Version 2.5 or later of the All Computers expanded-memory driver (ALLEMM4.SYS) is compatible with MS-DOS 5.0 HIMEM.SYS. Contact All Computers to get an updated driver.

3.3 Problems Loading into the Upper Memory Area --- Some computers with bus master DMA controllers may not be able to load device drivers or programs into the upper memory area. Try adding a DEVICE=SMARTDRV.SYS command before any DEVICEHIGH commands in your CONFIG.SYS file.

3.4 Intel Expanded-Memory Driver (EMM.SYS) -- If you use Intel's EMM.SYS driver with Aboveboard, use EMM.SYS version 4.0 revision D or later. If you have an earlier version, contact Intel for a free upgrade.

3.5 XMAEM.SYS and XMA2EMS.SYS - Setup disables the CONFIG.SYS commands that load XMAEM.SYS and XMA2EMS.SYS. If your system uses both drivers, replace the commands with a DEVICE=EMM386.EXE command in your CONFIG.SYS file.

If your system includes an XMA card, remove the REM command that precedes the DEVICE=XMA2EMS.SYS command in your CONFIG.SYS file.

3.6 Your third-party memory manager doesn't work after Setup - If you load high your third-party memory manager, such as QEMM- 386, Setup might not update the memory manager's device driver. If you load your memory manager high, carry out the following procedure:

1    Open your CONFIG.SYS or AUTOEXEC.BAT file with any text editor, and remove the command or switch that loads the memory manager high.

2    Run Setup again, and choose the Install MS-DOS Only option.

3    When Setup is complete, open your CONFIG.SYS or AUTOEXEC.BAT file with any text editor, and insert the command or switch that loads your memory manager high.

4    Save the file, and restart your computer by pressing CTRL+ALT+DEL.

4.8 Hardcard

a) Hardcard II

If you can't use Plus Development Hardcard II or Hardcard II XL when running EMM386.EXE, specify the exclude (x=) switch to prevent EMM386 from conflicting with the card's  BIOS address.

See your Hardcard II manual to determine which address space to exclude. See the MS-DOS User's Guide and Reference for more information about the exclude switch.

b) Hardcard 40 or Passport

If you are using Hardcard 40 or a Passport removable disk, and you have a DEVICE command for PLUSDRV.SYS in  your CONFIG.SYS file before installing Windows and  MS-DOS:

1. Disable or remove the DEVICE command for PLUSDRV.SYS command line in your CONFIG.SYS file. 2. Run Setup. 3. Re-enable or return the DEVICE command for PLUSDRV.SYS in your CONFIG.SYS file. Make it the last line in the file.

4.9 IBM PS/1, installing MS-DOS 5.0 --- If your IBM PS/1 stops running after installing Windows and MS-DOS, see &quot;MS-DOS or Windows won't start after running Setup&quot; in Chapter 4 of &quot;Getting Started.&quot;

4.13 Western Digital VGA Card - If you have a Western Digital VGA card and are using RAMBIOS.EXE and RAMBIOS.SYS, load RAMBIOS.SYS before ANSI.SYS and DISPLAY.SYS in your CONFIG.SYS file, and RAMBIOS.EXE before GRAPHICS.COM in your AUTOEXEC.BAT file.

4.14 ATI WonderCard 3.x --- If you have an ATI WonderCard, see &quot;Setup screens are unreadable&quot; in Chapter 3 of &quot;Getting Started.&quot;

4.15 XGA and EMM386.EXE --- If you use an XGA display with EMM386.EXE, you may need to exclude certain memory ranges with the EMM386 EXCLUDE option (x=). To determine which memory ranges to exclude, use the reference disk that came with your computer to view the memory map.

4.16 Zenith Computer

To use the GRAPHICS command with a Zenith computer, set the STACKS command in your CONFIG.SYS file to at least STACKS=9,256. For information about the STACKS command, see Chapter 14 of the MS-DOS User's Guide and Reference.

4.17 Zeos 486 and Task Swapper -- If you have a Zeos 486 computer with a Mylex BIOS, you may not be able to use Task Swapper in MS-DOS Shell. Contact Zeos for a ROM BIOS upgrade.
