SUMMARY
When using the Windows 3.0 or 3.1 Setup program to change from another
video type to EGA, you may encounter problems when trying to run
non-Windows-based applications in real (version 3.0 only) or standard
mode (versions 3.0 and 3.1).
If this change is made through the Windows Setup program, the device
line for EGA.SYS is not added to the CONFIG.SYS file. The loading of
this device file is essential to non-Windows-based applications
running within Windows 3.0.
MORE INFORMATION
The correct way to install both the video driver and the EGA.SYS file
is to run the Setup program from the Windows MS-DOS Prompt and allow
the Setup program to modify the CONFIG.SYS file.
If the EGA video driver is already installed from the Windows Setup
program inside Windows, either of the following processes may correct
the problem:
- Run Setup from the Windows MS-DOS Prompt and select a previously
unselected video driver. (If the display type that was installed
before EGA is chosen, Setup will not ask for any disks and the
SYSTEM.INI file will not be updated.)
- Once Setup is finished, run Setup again from the Windows MS-DOS
Prompt and change the video driver back to EGA. Allow Setup to
modify the CONFIG.SYS file when prompted.
-or-
- Because the EGA.SYS is the only utility missing, the Windows
EXPAND.EXE utility can be used to expand EGA.SYS from the Windows
installation disks. Manually insert the device line for EGA.SYS
into the CONFIG.SYS file.
- The EXPAND utility is located on Disk 2 of the 5.25-inch (1.2 MB)
and 3.5-inch (1.44 MB) disks, and Disk 5 of the 3.5-inch (720K)
disks. Copy the EXPAND.EXE file to the Windows directory. The
EGA.SY$ file (note the $ as the last letter in the compressed
EGA.SYS file) is located on Disk 3 of the 5.25-inch disks and on
Disk 5 of the 3.5-inch disks.
- From the WINDOWS directory, type the following to expand the
compressed EGA.SY$ file
c:\windows>expand a:ega.sy$ c:\windows\ega.sys
where c: is the drive and \windows is the installed location of
Windows 3.0.
- Use a text editor such as the Windows Notepad to add the following
line to the CONFIG.SYS file:
device=c:\windows\ega.sys
