This only works on some of my systems -- a big pile of Intel SuperMicro boxes w/Phoenix BIOS says "None" when I'm sure there's ECC, because I've seen some single-bit errors recovered. A brand new SuperMicro Nehalem box with a Megatrends BIOS does indicate ECC. On desktops, Intel 975 mobo correctly says ECC, while ASUS mobos with Megatrends BIOS say "None" while I think it's on. My bet is that this is part of the BIOS which is customized by the OEM, so we shouldn't blame Phoenix or Megatrends, and instead blame ASUS and SuperMicro. Poor QA at the least. I did discover one of my AMD servers was incorrectly configured, so this exercise was worthwhile. -- greg _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
