I did some memory area research with Nvidia card (to make both GPU working), with too block and bigger and one small one - one area B100-B1FF etc.. and discovered that those are free (Good), BAD not free, B is B000-B0FF,B100-B1FF etc.. :
GOOD: B:0,1,2,3,4,5,6,7 BAD:8,9,A,B,C,D,E,F
GOOD: C:E,F BAD:0,1,2,3,4,5,6,7,8,9,A,B,C,D
GOOD: D:0,1,2,3,4,5,6,7 BAD:8,9,A,B,C,D,E,F
GOOD: E:4,5,6,7,8,9,A,F BAD:0,1,2,3,B,C,D,E
With all of these ranges is Nvidia card booting too.
I dicovered that most free conv memory i have with these 2 ranges:
I=B000-B5FF NV-594/2 KB free conv/ largest free block, ATI-610/10
I=B000-B4FF (I=E800-E8FF or E900-E9F or EA00-EAFF or EF00-EFFF) NV-594/3 - best, ATI 610/10
Is some of these location better, safer etc?
Could you please also check if JEMM386 is compatible with DSDMA?
I did some more testing and you probably had sixth sense.. Without DSDMA.EXE all games under JEMM are running, without that strange error.
I also tried JEMMEX instead of HIMEM and JEMM, its even crashing on DSDMA.EXE
I using Yamaha drivers with patched DSDMA.exe otherwise on FX sounds on my board.
Im old goal oriented goatman, i care about facts and freedom, not about egos+prejudices. Hoarding=sickness. If you want respect, gain it by your behavior. I hate stupid SW limits, SW=virtual world, everything should be possible if you have enough raw HW.
