All recent BIOS releases have been fine. There was a bug in early BIOS releases for several A, X, and T ThinkPads that would cause a system lock-up when any partition with the final nibble of 0x5 was detected. FreeBSD uses 0xA5, and was caught by this. IBM put out a fixed BIOS that worked, but the next update, just a few days later, re-introduced the bug. It was removed again, as I recall, about 2 weeks later and has not re-appeared. If you have a remotely current version of BIOS on an A, R, T, or X series ThinkPad, you should be fine. (I am sending this from my T30 with bios updated about a month ago from the delivered BIOS which also worked fine.) R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
