No. It's NOT keyed to that BIOS. It's not keyed to ANYTHING. This laptop has a CD burner on it. It's also not running Windows. Want to make any guesses how many bits of the CDROM it burns are keyed to the BIOS? (To be pedantic about it, if the timestamp is keyed to ANYTHING on my laptop, it's keyed to the current system time on the host tick.uh.edu, since that's where my NTP chain goes back to, though of course if I was feeling evil I'd kill NTP and set the system time/date by hand....) Remember - if I'm an attacker, you have to assume that any CD I burn is like an episode of the Outer Limits - I control the horizontal and the vertical. ;) *Every single* bit on the CD is suspect unless you can *prove* otherwise...
