As another said if you have one of the earlier parallel printers that could work without Windwoes (there are still a few current models that do that), IOW prints straight ASCII, then capturing the BIOS screens is easy. While you are at each different screen just press "PrintScreen" or Shift-PrintScreen or Ctrl-PrintScreen. One of those should do it. Otherwise you will have to shoot with a camera.
. The trouble is, no OS or program has a chance to load before you enter the BIOS setup - so if the BIOS can't do it itself, then you're SOL..
