Hi folks,
I have a bizarre issue where my system doesn't seem to recognise that it is capable of EGA graphics unless I first load GEM.
It seems that running GEM somehow 'reminds' the system that it has an EGA capable graphics chip. Is it loading some sort of TSR or something?
eg. for King's Quest:
If I cold boot and run "SCIV.EXE" from DOS3.2 I get a black screen.
I can use the -C parameter to force CGA and it works
If I run "SCIV.EXE" from GEM it works as it should in EGA mode
Then if I quit GEM and go back to DOS it works as it should in EGA mode
This is also the case for Duke Nukem 1, Prince of Persia (will run in CGA mode using the -CGA parameter) and Commander Keen. There isn't enough memory to run Commander Keen or Duke Nukem from GEM but they work fine once I quit back to DOS. It's obviously not a huge issue but it is a bit of a pain to go through so many steps just to run a game...
Before running GEM
After running GEM
I can't replicate the issue in 86Box.
