Has it lived on planet corporate? Maybe the sysop disabled programming voltage.
It was previously owned by a major pharmaceutical company but I don't know how one would disable that, the extremely limited BIOS doesn't even give you any options beyond a hardware test.
EDIT: Ah, I think I finally figured it out! It seems that, according to this page of the manual anyway, that my system is locked down somehow, which is probably preventing the BIOS update. I don't get prompted for a password but I am unable to choose the "Start-up" or "Initialize" options in the Easy-Setup menu.
