I take it you're talking about the CPU cache?  I can only find
references to Cyrix cache stuff in the kernel, so by the BIOS seems the
only way to do it.  I guess I could expect some performance impact by
doing this, but I really don't know how big the cache is.  Maybe it is
time to updrade to a Pentium-type thingy...

I wasn't planning on rebooting that machine any time soon (it's my main
home box), but I'll try this (assuming that's what you mean) when I get
a chance.
