You might want to try this site http://ping4.ping.be/bios/ for finding information, and the c't-BIOS utility could also help you in determining exactly what type of motherboard you have, so that you can have a look at the manufacturer's web site, although there may not be any BIOS updates, manuals etc. available for a motherboard this old.
