The file DOS4GW.EXE is the DOS extender used to allow WChess to run
in protected mode. This file (and the file _W.W) is necessary in the
WChess directory.

TROUBLE WITH EMM386.

If your config.sys file contains a line similar to:

DEVICE=C:\DOS\EMM386.EXE

you may experience problems running WChess. You should use an editor
to modify the line to be:

DEVICE=C:\DOS\EMM386.EXE NOEMS NOVCPI

and reboot your computer or remove the line completely by putting an
REM in front as follows:

REM DEVICE=C:\DOS\EMM386.EXE

and reboot.
