Motherboard Reference Table

The purpose of this reference table is to give you the ability to easily locate information on your motherboard, such as the part number, the most current BIOS updates, settings for adding a processor, or even information on what has to be done in order to use a larger hard drive or more RAM. If you're unsure of what part number your motherboard is, first try to find your invoice. The part number will be there. If you don't have it or can't find it, reboot the system. When the system first boots, the BIOS revision will appear at the top of the screen. Note it and come back to this page. Click on the appropriate BIOS revision. The same BIOS may be used on several different part numbers in some cases, but the motherboards are almost identical, including the pertinent information.

Note: There will be more systems added to this as we go along, but we wanted to get some of them up in the meantime. Look for this section to greatly expand in the near future.

If you know your BIOS, use this chart:
