If you are running two or more programs that use expanded memory, call
Microsoft Product Support Services to obtain a new DOSSWAP.EXE file.
The updated file corrects problems associated with switching between
programs that use expanded memory.
If your computer hangs when you try to switch between programs that do
not use expanded memory, do the following:
• Make sure you are not running both MS-DOS Shell and Windows. Use
either MS-DOS Shell or Windows to switch between programs.
• Reinstall the DOSSHELL.GRB file in the directory that contains your
MS-DOS files. To do so, carry out the procedure described in the
Reinstalling the DOSSHELL.GRB File
The MS-DOS 5 Upgrade disks and the MS-DOS 6.0 and 6.2 Supplemental
disks include compressed files that are required for MS-DOS Shell to
work with different kinds of monitors. To reinstall the DOSSHELL.GRB
file, first determine which file is used with your monitor. Then
expand and copy the file to the directory that contains your MS-DOS
The following list shows the compressed file needed for each of the
monitors that MS-DOS Shell supports. Note that the name of the file on
the Upgrade disk is not DOSSHELL.GRB. Setup renames the file when it
copies the file to the directory that contains your MS-DOS files.
If you have this type of monitor Expand this file
EGA MONO EGAMONO.GR_
VGA, Super VGA. XGA, 8514, and other VGA.GR_
MONO (VGA, Super VGA. XGA, 8514, and VGAMONO.GR_
other high-resolution monitors
To reinstall the DOSSHELL.GRB file:
• Using the preceding list, determine which file you need to copy
from the Upgrade disks.
• If you are using MS-DOS 5.0, open the PACKING.LST file. This file
lists the contents of each disk. The file is in the directory that
contains your MS-DOS files. You can find PACKING.LST on Disk 3
(5.25-inch disks) or Disk 2 (3.5-inch disks).
If you are using MS-DOS 6.0 or 6.2, the MS-DOS Shell files are on the
Supplemental Disk. For more information on obtaining the Supplemental
Disk, see the coupon in the back of your printed MS-DOS documentation.
• Find the name of the file you need for your monitor, and write down
the location of the file.
• Use the following syntax to expand and copy the appropriate .GR_
file from the Upgrade disks to the directory that contains your MS-DOS
The <drive1:><path1> parameter specifies the location of the
compressed file you want to expand. The <filename> parameter specifies
the name of the compressed file. The <drive2:><path2> parameter
specifies the location of the expanded file.
expand <drive1:><path1><filename> <drive2:><path2>dosshell.grb
NOTE: Make sure you name the file DOSSHELL.GRB.
For example, if the VGA.GR_ file is on a disk in drive A, and you
want to expand the file to the \DOS directory on drive C, type the
following at the MS-DOS command prompt:
expand a:\vga.gr_ c:\dos\dosshell.grb
