Manual MS-DOS Installation When SETUP.EXE Fails

MORE INFORMATION

1. 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 step 1.
2. Transfer the MS-DOS system files to the hard disk drive with the following command:

         a:sys c:
   						

3. 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.
4. Create the directory C:\DOS.

1. Copy EXPAND.EXE from the MS-DOS Disk 1 (Setup) to the C:\DOS directory.
2. 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):

   COPY CON EXPALL.BAT
   %1
   FOR %%i IN (*.*) DO C:\DOS\EXPAND %%i C:\DOS\%%i
   C:
   CTRL + Z

3. 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 installing.
4. Rename the files expanded to the C:\DOS directory from their compressed names to their decompressed filenames.
   
   
   1. First rename the following files:

      rename dblspace.in_ dblspace.inf
      rename memmaker.in_ memmaker.inf

   2. Perform the following commands to rename the remaining files:

            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
      								

5. 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
