1.1 SpeedStor
If Setup referred you to this section and your computer has an OS/2 partition created by using the FDISKPM utility in OS/2 2.1, run MS-DOS Setup by typing SETUP /U at the command prompt.

If Setup referred you to this section and you have neither OS/2 nor a SpeedStor partition on your computer, see the section &quot;Setup displays the Incompatible Hard Disk or Device Driver screen&quot; in the &quot;Diagnosing and Solving Problems&quot; chapter of the MS-DOS 6 User's Guide.

If you do have a SpeedStor partition on your computer, Setup probably referred you to this section for one of the following reasons:


 * Setup could not find in your CONFIG.SYS file a command 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.
 * Your CONFIG.SYS file has a DEVICE=HARDRIVE.SYS line in it. If this is the case, carry out the following procedure:


 * 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.

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.
 * 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.
 * Restart your computer.
 * Make sure you can access your hard disk.
 * 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 6.2. 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 6.2:


 * 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 6.2 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 6.2. 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 6.2. 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 6.2.


 * 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.
 * 1) At the command prompt, type FORMAT C: /S to reformat your startup drive and transfer MS-DOS 6.2 system files to it.
 * 2) Remove the disk from drive A, and restart your computer.
 * 3) Insert Setup Disk 1 in drive A or B, and type A:SETUP or B:SETUP at the command prompt.
 * 4) 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.
 * 1) 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 installed, but does not have 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


 * 1) Run Setup by inserting Setup Disk 1 in drive A and restarting your computer. Complete Setup by following the instructions on the screen. When Setup is complete, Windows NT will be disabled.

If Windows NT was installed on a FAT partition, complete steps 2 and 3 of this procedure to reenable Windows NT so that you can use both the Windows NT and MS-DOS operating systems.

If Windows NT was installed on a non-FAT partition, see section 1.9.
 * 1) Insert your Windows NT Setup disk in drive A or drive B, and then restart your computer.
 * 2) When the Windows NT Setup screen appears, choose Repair, and then insert your Windows NT Emergency Repair Disk (which you created when you installed Windows NT) to repair the Windows NT system files.

Procedure 2


 * 1) When you start your computer, choose MS-DOS as your operating system.
 * 2) 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 6.2 and preserve your partition or files:


 * 1) Run MS-DOS Setup.
 * 2) When prompted, choose to continue Setup without removing the partition or files.
 * 3) After Setup is complete, insert your Windows NT Setup disk in drive A or drive B, and then restart your computer.
 * 4) When the Windows NT Setup screen appears, choose Repair, and then insert your Windows NT Emergency Repair Disk (which you created when you installed Windows NT) to repair the Windows NT system files.
