Cyrix 486 substitute chips (the ones that plug into ordinary 386 MBs) handle freebsd correctly with a 1542B? They claim some sort of cache coherency trick; snooping would work if the motherboard is right (mine is a medium old C&T PEAK/DM with AMI bios). Does anyone know if a) snooping is the cache coherency trick? b) if the PEAK/DM relays addresses back to the processor on bus-master cycles? (would be nice to get "decent" performance from my old 386.) Thanks in advance, -- Pete
