Yeah, the IRQ is 5 under windows and 7 under DOS. But since I like the XG synth, I usually set the midi address to GM 330 so I'm used to this (and I'll probably play under pure DOS only games that have problems under windows)
Also thanks for the VIA advice, but this isn't the real propose of that computer. I'm building it into the best achievable gaming machine of 1998. Some people already projects like these, but I found the sound part a little lacking in comparison to the rest (Sound blaster Live in every computer I saw). I really like the YMF724 and all it's capabilities, and even though that DOS support isn't really the most important thing of that machine, I do like to have my hardware fully functionnal (and for now, to play duke3D with proper sound, this is required). But like I said, I'd like to add a SB AWE 64 because it has some advantages that can stack upon the YMF724, and the ymf can compensate some of the disadvantages of the SB AWE64 (no sb pro compatibility, no real opl3 ...).
But I think I will also add a third sound card 🤣 : the Aureal3D Vortex 1 or 2 (I didn't really looked which one is the most time accurate of the two) for better 3D sound in windows. I don't know if 3 sound cards will cooperate, but I hope it will ! (I already managed to run 2 different sound cards in the same machine, so why not 3 ? Especially if some features of one are better than the other, I'll just need to desactivate it)
So yeah, the goal of that computer is to be able to run late DOS games/Windows 9x games maxed out to their best potential. For older games, I just have older machines ^^
Before I finish, I just have a few more questions : what are CT-VOICE and SBFMDRV.COM for ? Some games do need them ?
In order to initialize the sound card under dos, I need to add into autoexec.bat "setupds /s", right ?
I guess that the answer is yes because games crashed if I don't type this first ^^
Oh and again
Thank you very munch guys ! 😁
