If a regular or manual installation of MS-DOS fails because SETUP.EXE does
not run correctly, you may be able to use a batch file called EXPALL.BAT to
perform a successful manual installation. EXPALL.BAT is discussed on pages
553-554 of the Microsoft Windows 3.0 "User's Guide." This file was
originally designed to perform a network installation of Windows 3.0. In
the steps below, it has been adapted to perform an installation of MS-DOS
to the C:\DOS subdirectory.
• Boot your machine with Disk 1 (Setup) of the MS-DOS disk set you are
upgrading to by inserting the disk in drive A and pressing CTRL+ALT+DEL.
When the message "Starting MS-DOS ..." appears on the screen, press the
F5 key to bypass MS-DOS Setup.
IMPORTANT: If your Disk 1 fits in drive B only, you must first install
MS-DOS to a floppy disk in drive A (use the command B:\SETUP /F). Then
boot with the floppy disk created in drive A and follow the above
instructions. If SETUP /F does not run, you must obtain a copy of MS-DOS
that is the same media type as your boot disk drive and then perform
• Transfer the MS-DOS system files to the hard disk drive with the
• Make sure Disk 1 is no longer in drive A. Reboot your machine from the
hard disk drive, and press F5 when the message "Starting MS-DOS ..."
appears on the screen to ensure no unnecessary drivers are loaded.
• Create the directory C:\DOS.
NOTE: We do not recommended that you copy files from the disk created with
the SETUP /F command to C:\DOS because all MS-DOS files are not present on
• Copy EXPAND.EXE from the MS-DOS Disk 1 (Setup) to the C:\DOS directory.
• Change to the C:\DOS directory on the hard disk, and create EXPALL.BAT
with COMMAND.COM by typing the following lines (be sure to press ENTER
after each line):
• Run EXPALL.BAT with the source disk drive indicated (such as EXPALL A:
or EXPALL B:). The command must be repeated for each disk you are
COPY CON EXPALL.BAT
FOR %%i IN (*.*) DO C:\DOS\EXPAND %%i C:\DOS\%%i
CTRL + Z
• Rename the files expanded to the C:\DOS directory from their compressed
names to their decompressed filenames.
• First rename the following files:
• Perform the following commands to rename the remaining files:
rename dblspace.in_ dblspace.inf
rename memmaker.in_ memmaker.inf
rename *.38_ *.386
rename *.bi_ *.bin
rename *.co_ *.com
rename *.cp_ *.cpi
rename *.dl_ *.dll
rename *.ex_ *.exe
rename *.ov_ *.ovl
rename *.sy_ *.sys
rename *.tx_ *.txt
rename *.gr_ *.grp
rename *.hl_ *.hlp
rename *.ls_ *.lst
rename *.pr_ *.pro
• Copy the files WINA20.386 and DBLSPACE.BIN (or DRVSPACE.BIN in MS-DOS
6.22) to the root directory, and set the attributes of DBLSPACE.BIN or
DRVSPACE.BIN to Hidden, System, and Read-Only by using the ATTRIB
command as follows:
c:\dos\attrib c:\???space.bin +r +s +h
