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:
* 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:
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.
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 "Using Fdisk to Configure Your Hard Disk"
in the chapter "Diagnosing and Solving Problems" 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 "Your computer uses a disk-compression
program that is incompatible with Setup" 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
"Freeing Disk Space" 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 "Setup did
not find the files it needs in the directory specified" 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 "Using Fdisk to Configure Your Hard
Disk" in the chapter "Diagnosing and Solving Problems" 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 "Using Fdisk to Configure Your
Hard Disk" in the chapter "Diagnosing and Solving Problems" 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 "Setup displays
the 'Your computer uses password protection' screen" in the chapter
"Diagnosing and Solving Problems" 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 "Setup displays the 'Your computer is using an
incompatible delete-protection program' screen" in the chapter
"Diagnosing and Solving Problems" 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 "?" 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 "Getting Started"
in the MICROSOFT MS-DOS 6 USER'S GUIDE. When Setup displays the
"Your CONFIG.SYS file contains commands that are not valid MS-DOS
commands" message, choose the "Modify original files" 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 "Your CONFIG.SYS file contains commands
that are not valid MS-DOS commands" message, choose the "Modify
original files" option.
When Setup displays the "Because you are currently using the
DR DOS operating system" message, choose Continue.
8. After Setup is complete, MS-DOS displays an "Unrecognized
command" 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 "You need to install
MS-DOS manually" in the chapter "Diagnosing and Solving Problems" 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 "Your computer uses password protection"
screen.
----------------------------------------------------------------
See section 1.10.
1.14 Setup displays the "Your computer is using an incompatible
delete-protection program" 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 "You need to install MS-DOS manually"
in the chapter "Diagnosing and Solving Problems" 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.
