    hey all, was just wondering if it's possible for this to happen? can the motherboard BIOS write to the HDD? i'm asking because i'll be buying a 2nd hand mboard.

    never used an old mboard before so i was just wondering.

    thanks

    Yes, it is possible for a bios to have been infected. That is why some boards have a bios protect jumper; to stop a virus from writing to the bios.

    Note is is NOT common but it is possible.

    Read the PDF file I referenced in post #6. If you are that worried about purchasing a used motherboard with a virus in the BIOS the solution is simple, don't purchase the motherboard.

    Anytime you purchase a used motherboard "caveat emptor" applies.

    what does caveat emptor mean?

    is there any way to tell if there was a virus in the BIOS?

    Caveat Emptor. Latin for let the buyer beware. You are buying a used part, of course it is not in the same condition as a new part.

    As I posted, a bios virus is rare however not impossible. If you are really really worried, then order a new bios chip from either the board maker or badflash.net. Install the new chip and you have no worries.
