BSD Still Won't Run on IBM ThinkPads?

omega_cubed asks: "'You've successfully installed FreeBSD, now your computer is going to hang at boot up!' -- That was what I just recently suffered. I've been running Mandrake on my ThinkPad X20 for almost a year. But the lack of high speed internet connection over the summer prevented me from keeping up with the various patches/updates. Many services--sendmail, apache, etc.--were shutdown one by one because of security vulnerabilities. Recently I decided that instead of trying to catch all those patches I missed in the last few months, I might just as well do a clean install of FreeBSD. I've done what I think was all the preparations necessary: I backed-up all my files, checked all the hardwares for possible conflicts (on FreeBSD.org) and supports, downloaded the ISO image. And I decided the computer should be able to take it. Unfortunately, I didn't come across the old slashdot article reporting a possible conflict between IBM ThinkPad's BIOS and FreeBSD's filesystem. So last night, after much struggling, I installed FreeBSD. It finished, rebooted, and the computer now just hangs at bootup (here's a more detailed report on what happened). It doesn't even go into BIOS. Does anyone have experience dealing with this? Is there anyway I can update the BIOS? The diskettes provided IBM were not able to boot the computer, and I am at a loss here. Thanks."
