Was hoping to bring it down to a P200 era for some speed sensitive games. But I think i overshot a bit with disabling the cache.

100x slower is not exactly great scaling try to fiddle with slowdown programs like SlowDos, they have their issues too, but they mostly work and there is multiple of them, so i one dont, you still have some options..

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.

I have a SL2YM Slot-1 Pentium 2 processor in my M748MR mobo, which I can configure from the BIOS as 4x66MHz=266MHz and 4x100MHz=400MHz. Can I switch between the two modes with SetMul or some alternative tool?

There are some tools like SoftFSB https://www.majorgeeks.com/files/details/softfsb.html
But it needs to support the PLL chip on your motherboard. And I don't see M748MR mentioned in the file SoftFSB.dat. A SiS 620 based PC-Chips motherboard is rather uncommon...

It's sad to hear but thanks for responding.
