Hia,
I have a Dell Optiplex GN+ motherboard that I'm trying to setup as a nice Pentium MMX 166MHz DOS gaming setup with a wide range of speed options for older time sensitive games. My plan is once I've got it working (still trying to get power to it as not standard power connector) to use SetMul options but it would be nice to also be able to disable Level 2 motherboard cache, however Dells proprietary BIOS isn't supposed to have that ability.
Looking at the Intel 430TX there seems to be a Cache Control register (CC) that you can set cache to Zero which disables it - does anyone know of a utility that can do this or have tips for setting these registers maybe using Debug or in Assembly?
Cheers!
