This month I built a P233MMX system to act as a 136 in 1 Windows 95 & DOS PC similar to that built on PhilsComputerLab. It works great with newer games, but I'm having trouble with Setmul for older DOS games.

Setmul can enable and disable the L1 cache and BPD, VPD, etc. It shows that it can disable the L2 cache. However, when I try to disable the L2 cache nothing happens. I don't have this problem on my other Socket 7 motherboard with an OptiViper chipset, so this makes we wonder if there is some issue with setmul and the 430TX in my newly built system.

Further, even when I disable L1 cache and all the BPD, VPD, etc. options, the system still seems to run too fast. Falcon 3.0, for instance, exhibits the annoying "sound faster than animation" overspeed bug on this system unless I turn of the L2 cache in BIOS and disable the L1 cache with setmul. I know for a fact that Falcon 3.0 runs just fine on a Pentium 100 with nothing disabled and will run just fine on a Pentium 200 with L1 cache disabled. What makes the 233MMX so different in these cache disabled situations?
