It is Phoenix Award Bios V1.0.7. It does not have any settings that I could find anything about CPUID LIMIT anywhere. Where might it be? I went back and booted "2.6.23.15-137.fc8 #1 SMP Sun Feb 10 17:48:34 EST 2008 i686 athlon i386 GNU/Linux", which I also know was running w/ 2 cores happily for a while, but it too shows just one core. So it is not 2.6.23 versus 2.6.24 issue as far as I can tell. Very puzzling - something else must have changed during the updates(?)
