Hallo Alexandre,
I didn't get the NT version of Galep to install under wine. There is some
deadlock with the Win16Mutex. It would be nice if someone could have a look
at that problem. The installation file is found at
http://conitec.net/hardware/down/119NTUK.EXE
Copying the galep directory from a NT machine, I can successfully run the
executable with winver "win31/win95/win95", without hitting the SetSelectorBase
problem.
Running with --winver nt40 however gives:
hertz:> wine --winver nt40 galep3.exe
fixme:event:EnableHardwareInput16 (0) - stub
fixme:event:EnableHardwareInput16 (1) - stub
fixme:win32:DEVICE_Open Unknown VxD glpntdrv. Try --winver nt40 or win31 !
and the device is not accesible.
PS: Sould I submitt a patch to emitting a warning when SetSelectorBase wants
an illegal region? I think all memory about 0x80000000 is not allowed on
normal ix86 linux, while with the bigmen option it is 0xc0000000? Can I
determine this number during runtime?
Bye
