I'd expect MPTable:, Timecounter, and CPU: lines above your quoted material. Definitely have BIOS/OS issues, though. As Chuck suggests, play around with the PnP settings in your BIOS setup, possibly update.... I've got a box similar to yours, I *think*; unfortunately, it's be on a distant job site for over two years (originally running 5.3-RELEASE with SMP on two Pentium-III Lancewood chips), and it's been so long since I was in the BIOS on that box I've no idea what the settings are. > Several possible clues in that snippet, now that I look at it.
