By "early" I meant the cpu and mainboard were bought as soon as K7's
showed up in the OEM channel.
I'm beginning to suspect it my be a mainboard problem, though I'm not sure
how that would tie in with mtrr. Have to see if I can scrounge up a
different motherboard, or see if there is a bios upgrade I can flash...
Thanks,
