No difference with L2 (external cache) off? With DRAM wait states set to the highest? With L1 (internal cache) off? WAIT... is usually when the BIOS switches from the pessimistic settings burned into the BIOS ROM, to whatever you've configured in the CMOS setup.
If L2 off helps, something is too aggressive for your bus speed or cache chips. Likewise with DRAM wait states and your SIMMs. L1 off helping would indicate a problem with the L1 write-back stuff although usually it would get past that point and hang when booting from a floppy.
I'll try turning on a wait state and see if that makes a difference... This is really kind of a strange thing. It just doesn't like anything more than 100mhz but apparently it hates amd now too.
