make sure you have athlon support ... or you're dead,
some p3/p4 instructions will crash on athlons

make sure you have smp turned on in the kernel
	( top -i should list both cpu .. easy/simple test )

make sure you have ecc or no ecc set properly for your bios for the memory

make sure you have the cpu and memory fsb setings correctly set for
pc-2100 or pc-2700 memory

c ya
alvin
- ever wonder why cpu's have a 400Mhz or 533Mhz fsb but the memory is only
  a 266Mhz fsb ( pc-2100 )  or 333Mhz fsb ( pc-2700 ) ??
	http://www.linux-1u.net/Memory/#DDR
	-- 533Mhz fsb cpu just sitting and waiting on memory ??
