    It will surely vary from computer to computer (and BIOS to BIOS), but you can try looking at dmidecode.

    Just run the command (as root) in your terminal, and you should get a lot of low-level hardware information. The BIOS portion is usually at the top of the output. E.g., on my machine:

    dmidecode|awk '/^BIOS Info/,/^$/'
    yields this:
