The DOSSHELL.INI file in MS-DOS 6.0 does not contain references to the
MS-DOS 5.0 BACKUP and RESTORE commands.
Since Setup doesn't update a existing DOSSHELL.INI file, the existing
references to Backup Fixed Disk and Restore Fixed Disk are not
updated. BACKUP.EXE is copied to the OLD_DOS directory so that the
Backup Fixed Disk option no longer works. You can either copy the
MS-DOS 5.0 BACKUP command (BACKUP.COM) to the DOS directory or modify
the Backup Fixed Disk properties to reference the new backup program,
Microsoft Backup (MSBACKUP.EXE).
If you don't have an existing DOSSHELL.INI file, Setup creates a new
one with the following default items:
Disk Utilities Menu
Setup leaves the RESTORE command (RESTORE.EXE) from MS-DOS 5.0 in the
DOS directory even though it does not appear as an item in MS-DOS 6
Shell. The BACKUP command (BACKUP.EXE) from MS-DOS 5.0 is available on
the supplemental disk or in the OLD_DOS directory as described above.
To replace your existing DOSSHELL.INI file, you can expand the
appropriate .IN_ file from the original MS-DOS 6 Upgrade disks. For
example, if you have an EGA or VGA video display card, expand EGA.IN_
from the MS-DOS 6 Upgrade disks (Disk 2 of the 1.2-megabyte (MB) set
or Disk 1 of the 1.44-MB set). For example, if you insert the Setup
disk in drive A, you would type the following command:
expand a:ega.in_ c:\dos\dosshell.ini
If the new utilities made available by the MS-DOS 6.0 DOSSHELL.INI
file are not installed, you must install them using the SETUP command
with the /E parameter.
