Right now I have something like this going on.
A: is the floppy bootup image.
B: could be a floppy so I don't want that to be probed
Y: is the drive letter assigned to the CD that I booted from.
Z: is a ramdrive.
for %%d in (c d e f g h i j k l m n o p q r s t u v w x) do (
if exist %%d:\mygame\ (
cls
echo.
echo.
echo.
echo A previous installation of MYGAME was found on drive %%d:
choice /B /N /C:YN /T:Y,10 Should I run the game from this location
[recommended]
if not errorlevel 2 (
swsubst %progdisk% %%d:\mygame\
goto finish
)
)
)
REM either didn't find an installation, or didn't want to use it
set progdisk = z:
copy Y:\mygame\*.* %progdisk% > nul
:finish
%progdisk%
rungame
FreeDOS doesn't seem to like the compound IF very much. Thoughts
appreciated.
