1. SETUP

=
1.1 SpeedStor - 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. Make sure you copy the SSTOR.SYS file to the same path as the HARDRIVE.SYS file.
 * Your CONFIG.SYS file has a DEVICE=HARDRIVE.SYS line in it.

See the PACKING.LST file on Setup Disk 1 for the location of the SSTOR.SYS file on the Setup disks and for instructions on how to expand and copy it to your hard disk.

2. Replace the DEVICE=HARDRIVE.SYS command with a DEVICE=SSTOR.SYS command. For example, if the command that loaded the HARDRIVE.SYS file was DEVICE=C:\SSTOR\HARDRIVE.SYS, you would replace it with DEVICE=C:\SSTOR\SSTOR.SYS.

3. Restart your computer.

4. Make sure you can access your hard disk.

5. Run Setup.

1.2 Incompatible Hard Disk or Device Driver --- If Setup referred you to this section, and no other section in this file is relevant to your system, you have a partition that is incompatible with MS-DOS 6. You must delete the partition from your hard disk. See &quot;Using Fdisk to Configure Your Hard Disk&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

1.3 AT&T 6300 Computer -- If you use an AT&T 6300 computer and your ROM BIOS is version 1.21, contact your vendor for a ROM BIOS upgrade. The ROM BIOS version number is displayed when you start your computer.

1.4 Toshiba with a Hard RAM Disk

These instructions apply to Toshiba models T1200, T1600, T1200XE and T1000LE.

To use the hard RAM disk, carry out the following procedure before you install MS-DOS 6:

1. Back up your hard RAM disk.

2. Using the Toshiba Setup program, delete the hard RAM disk by allocating zero kilobytes (KB) to it. All data on  the hard RAM disk will be lost.

3. Restart your computer

4. Run MS-DOS 6 Setup.

5. After Setup is complete, run 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.

1.5 Tandy with ROM DOS -- Contact your hardware manufacturer for information about upgrading a Tandy computer with ROM DOS to MS-DOS 6. This applies to the following models: 1000EX, 1000HX, 1000SL, 1000SL2, 1000TL, 1000TL2, 1000TL3, 1000RL, 1000RLX, 1000RL-HD, 1000RLX-HD, 1100FD, 2500XL, 2500XL2.

1.6 Setup displays the &quot;Your computer uses a disk-compression program that is incompatible with Setup&quot; message. -- If Setup indicated that your computer has an incompatible disk-compression program, you must remove it manually before you can install MS-DOS 6. Carry out the following procedure.

NOTE This procedure will replace your current disk-compression software with DoubleSpace. As an alternative, contact your disk- compression vendor for an updated version of your software. In most cases, current versions of disk-compression software are compatible with MS-DOS 6.

1. Back up all the files on your compressed drive. In step 3, you will format your uncompressed drive, which destroys all the files on your compressed and uncompressed drives.

2. If your Setup disks are compatible with drive A, insert Setup Disk 1 in drive A, and restart your computer. After Setup displays the first screen, quit Setup by pressing F3 twice.

If your Setup disks are not compatible with drive A,  create a startup floppy disk for drive A. To do this, insert Setup Disk 1 in drive B, and a blank floppy disk in drive A. Then type B:SETUP /F at the command prompt.

When prompted, choose to install MS-DOS on the floppy disk in drive A. After Setup is finished, leave the disk in drive A,  and restart your computer.

3. At the command prompt, type FORMAT C: /S to reformat your startup drive and transfer MS-DOS 6 system files to it.

4. Remove the disk from drive A, and restart your computer.

5. Insert Setup Disk 1 in drive A or B, and type A:SETUP or  B:SETUP at the command prompt.

6. After Setup is complete, type DBLSPACE at the command prompt, and follow the instructions on your screen.

For more information about DoubleSpace, see the chapter &quot;Freeing Disk Space&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

7. After you have installed DoubleSpace, restore the files you backed up. Do not restore older versions of MS-DOS files.

1.7 You deleted files from the directory that Setup needs to install the optional Windows programs. - If you typed BUSETUP /E at the command prompt, the &quot;Setup did not find the files it needs in the directory specified&quot; message appeared, and you think you deleted the files from your hard disk, insert Setup Disk 1 in drive A or B, and start Setup by typing A:SETUP /E or B:SETUP /E at the command prompt.

1.8 Running Setup if Your Computer Uses Windows NT -- If your computer has Windows NT, but not MS-DOS installed on it, carry out Procedure 1. If your computer has Windows NT and MS-DOS installed on it, carry out Procedure 2.

Procedure 1

o Run Setup by inserting Setup Disk 1 in drive A, and restarting your computer.

NOTE Windows NT will be disabled after Setup. If Windows NT  was installed on a FAT partition, and you want to reenable it, install Flexboot so you can access both the Windows NT and MS-DOS operating systems.

If Windows NT was installed on a non-FAT partition, see section 1.9.

Procedure 2

1. Make sure you have installed Flexboot on your computer.

2. When you start your computer, choose MS-DOS as your operating system.

3. Run Setup by inserting Setup Disk 1 in drive A or B, and typing A:SETUP or B:SETUP at the command prompt.

1.9 Setup detects that your computer has a non-MS-DOS partition or     non-MS-DOS files, and your computer uses Windows NT --- The procedure you use depends on whether you want to preserve the partition and its files. Find the section below that describes the configuration you want.

You Don't Want to Preserve the Partition or its Files -- If you don't want to preserve the partition or its files, choose to remove the partition or files if Setup prompts you to do so. If Setup doesn't offer you that choice, remove the partition manually after Setup is complete. For instructions on removing a non-MS-DOS partition manually, see &quot;Using Fdisk to Configure Your Hard Disk&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

You Don't Want to Preserve the Partition but Want to Save its Files --- If you want to save the data files, but don't want to preserve the partition, back up the files, run Setup again, and then choose to remove the partition or files if Setup prompts you to do so. If Setup doesn't offer you this choice, remove the partition manually after Setup is complete. For instructions on removing the partition manually, see &quot;Using Fdisk to Configure Your Hard Disk&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

You Want to Preserve the Partition and Its Files

Carry out the following procedure.

NOTE If the non-MS-DOS partition takes up all the space on your hard disk, you must reconfigure your hard disk. You can either let Setup do it for you, as described in the preceding section, or reconfigure it yourself manually. For instructions on reconfiguring your hard disk manually, see your Windows NT documentation.

To install MS-DOS 6 and preserve your partition or files:

1. Run Setup again.

2. When prompted, choose to continue Setup without removing the partition or files.

3. After Setup is complete, install Flexboot.

With Flexboot, you should be able to access both the MS-DOS and Windows NT operating systems.

1.10 Setup detects that your computer uses DR DOS. -- If you have DR DOS installed on your computer, take the following precautions before restarting Setup:

o If your system has any security features, including password protection, disable them. For more information, see &quot;Setup displays the 'Your computer uses password protection' screen&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

If you have protected any files or directories with a password, remove the password protection, particularly if you have protected your CONFIG.SYS or AUTOEXEC.BAT files, or your DR DOS directory.

o If you have DELWATCH installed on your computer, carry out the procedure &quot;Setup displays the 'Your computer is using an incompatible delete-protection program' screen&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

o If your CONFIG.SYS or AUTOEXEC.BAT files use any conditional commands--such as the &quot;?&quot; or GOTO commands--remove them and adjust the order of commands in your startup files accordingly.

o If your CONFIG.SYS file uses the CHAIN command, remove it and adjust the order of commands in the file accordingly.

o If your computer uses disk compression, but drive C is not compressed, run Setup as described in the chapter &quot;Getting Started&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE. When Setup displays the &quot;Your CONFIG.SYS file contains commands that are not valid MS-DOS commands&quot; message, choose the &quot;Modify original files&quot; option.

If drive C is compressed, carry out the following procedure:

1. Determine which drive is your original uncompressed drive. For more information, see your DR DOS documentation.

2. Make backup copies of the CONFIG.SYS and AUTOEXEC.BAT files on    your compressed drive, and the DCONFIG.SYS file on your uncompressed drive.

3. Combine the two configuration files. For example, if drive D is    your uncompressed drive, type the following at the command prompt:

COPY D:\DCONFIG.SYS+C:\CONFIG.SYS D:\CONFIG.SYS

4. Copy the combined CONFIG.SYS file to drive C. For example, if    drive D is your uncompressed drive, type the following at the command prompt:

COPY D:\CONFIG.SYS C:\CONFIG.SYS

5. Copy your AUTOEXEC.BAT to your uncompressed drive. For example, if drive D is your uncompressed drive, type the following at the command prompt:

COPY C:\AUTOEXEC.BAT D:\AUTOEXEC.BAT

6. Run MS-DOS 6 Setup.

7. When Setup displays the &quot;Your CONFIG.SYS file contains commands that are not valid MS-DOS commands&quot; message, choose the &quot;Modify original files&quot; option.

When Setup displays the &quot;Because you are currently using the DR DOS operating system&quot; message, choose Continue.

8. After Setup is complete, MS-DOS displays an &quot;Unrecognized command&quot; message on your screen for each command in your AUTOEXEC.BAT and CONFIG.SYS files that is not a valid MS-DOS command. Remove these commands from your CONFIG.SYS and AUTOEXEC.BAT files.

9. Add the DEVICE=HIMEM.SYS command to the beginning of your CONFIG.SYS file, and the restart your computer.

1.11 Installing MS-DOS on a Drive Other Than C -- As described in the following procedure, you can install MS-DOS on a drive other than C by using the /M switch to copy the system files to your startup drive and then using the /Q switch to copy your MS-DOS files to a different drive.

NOTE This procedure is designed for advanced users. If your computer uses disk-compression software, modify the procedure as appropriate.

NOTE If your computer uses disk-partitioning software, such as Disk Manager, SpeedStor, Priam, or Everex, do not carry out the procedure until you have carried out steps 1 through 3 of &quot;You need to install MS-DOS manually&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE. If your software uses a driver to enable the drive on which you want to install MS-DOS, make sure you create a startup disk with the driver in a CONFIG.SYS or AUTOEXEC.BAT file. After you have carried out these steps, skip to step 3 of the following procedure.

1. Run Setup by inserting Setup Disk 1 in drive A or B, and typing A:SETUP /M or B:SETUP /M at the command prompt.

NOTE Your CONFIG.SYS and AUTOEXEC.BAT files were saved as   CONFIG.NEW and AUTOEXEC.NEW.

2. Run Setup by inserting Setup Disk 1 in drive A or B, and typing A:SETUP /Q or B:SETUP /Q at the command prompt. Follow the instructions on your screen.

3. When Setup displays the system settings screen, choose the MS-DOS Path option. Type the drive and directory where you want to install MS-DOS, and press ENTER. Continue Setup.

4. After Setup is complete, open your CONFIG.NEW and AUTOEXEC.NEW files and ensure that their commands specify the correct path. Save the files as CONFIG.SYS and AUTOEXEC.BAT. Then restart your computer.

1.12 Bypassing the Uninstall Disk and Using Default Setup Options - To keep Setup from creating an Uninstall Disk, use the /G switch with the Setup command.

To bypass the Uninstall disk and use default Setup options instead of choosing them yourself, use both the /H and /G switches with the Setup command.

WARNING The primary purpose of the Uninstall disk is to safeguard your files during and after Setup. If Setup doesn't create an Uninstall disk, you will not be able to restore your previous version of DOS. If Setup should render your hard disk inaccessible, you will not be able to use the Uninstall disk to make it accessible again.

NOTE If you have a version of MS-DOS earlier than 5.0, and you use the /G switch or the /H and /G switches together, Setup will not prompt you if you need to update your network files.

1.13 Setup displays the &quot;Your computer uses password protection&quot; screen.

See section 1.10.

1.14 Setup displays the &quot;Your computer is using an incompatible delete-protection program&quot; screen. --- See section 1.10.

1.15 Installing MS-DOS 6 on a System with a CorelSCSI UNI_ASP.SYS Driver

If your system uses the CorelSCSI UNI_ASP.SYS device driver for optical drives, and Setup stops running when you try to install MS-DOS 6, delete the DEVICE command in your CONFIG.SYS that loads the Corel UNI_ASP.SYS driver. Then run Setup again. After Setup is complete, reinstall the Corel UNI_ASP.SYS driver as you originally installed it. If you continue to have problems, contact Corel Customer Service.

1.16 Installing MS-DOS 6 on a Computer with Micro House DrivePro

If you use Micro House DrivePro or a similar product that uses a proprietary Master Boot Record (MBR), install MS-DOS 6 by following the procedure in &quot;You need to install MS-DOS manually&quot; in the chapter &quot;Diagnosing and Solving Problems&quot; in the MICROSOFT MS-DOS 6 USER'S GUIDE.

NOTE If you want to install Microsoft Anti-Virus, Backup, or Undelete after Setup is complete, rerun Setup by typing SETUP /U /E.

1.17 How to set up the Icelandic keyboard - To set up the Icelandic keyboard, carry out the following procedure:

1. Expand and copy the KEYBOARD.IC_, COUNTRY.IC_, and EGA.IC_ files from your Setup disks to the directory that contains your MS-DOS files. For the location of the files on the disks and for instructions on how to use the EXPAND command, see the PACKING.LST file on Setup Disk 1. When you use the EXPAND command, name the files KEYBOARD.SYS, COUNTRY.SYS, and EGA.CPI

2. In your CONFIG.SYS file, add the two following lines. For example, if the directory that contains your MS-DOS files is DOS, add the following lines:

COUNTRY=354,861,C:\DOS\COUNTRY.SYS DEVICEHIGH=C:\DOS\DISPLAY.SYS CON=(EGA,,1)

3. In your AUTOEXEC.BAT file, add the following line:

MODE CON CP PREPARE=((861) C:\DOS\EGA.CPI) MODE CON CP SELECT=861 KEYB IS,,C:\DOS\KEYBOARD.SYS

4. If you also need support for codepage 850, then add the following to your CONFIG.SYS file:

COUNTRY=354,861,C:\DOS\COUNTRY.SYS DEVICE=C:\DOS\DISPLAY.SYS CON=(EGA,,2)

Add the following to your AUTOEXEC.BAT file:

NLSFUNC MODE CON CP PREPARE=((861,850) C:\DOS\EGA.CPI) MODE CON CP SELECT=861 KEYB IS,,C:\DOS\KEYBOARD.SYS

5. Restart your computer.
