Decided to ratchet down my P3 rig to play DOS games from 94 on up. Planning to use a 233mmx Pentium on a SE440BX board with a Starfighter 3D 8MB AGP, 64MB ram, 40GB hard drive, SB 32pnp. Still will run win98SE for early 98 games and such. My question is will I still have speed problems with the DOS games and if so can messing with the Bios help?
As mmx_91 said, you can't use a 233mmx on an SE440BX.
Given that you are starting with a P3, I'm guessing your speed problems are related to old games playing too fast?
I will tell you that on my Pentium 133, there are some DOS games that need more CPU to run smoothly. For example, Descent2, System Shock, US Navy Fighters, Duke Nukem 3D, and Cybermage all suffer from varying degrees of lag or low FPS. I have a faster DOS machine (Celeron 333) that runs all of these games smoothly. The reason I am sticking with the Pentium 133 for now is because using SETMUL to disable cache, I am able to drop the speed to just about perfect for running Wing Commander. The Celeron 333, when run with SETMUL, actually becomes too slow for Wing Commander. So my plan is to finish WC1, then swap systems. 😀
That said, I'm not sure how the 233mmx will fare with SETMUL. That's what you should try first (assuming you have a motherboard that cpu will run in). I imagine the 233mmx will be enough for the more demanding DOS games, just not sure how it will work with slowdown methods. Let us know!
