Some manufacturer motherboards are based on board available retail. I have a Dell e510 and was wondering if anyone knows if the e510 board is based of a retail board as well. Dell calls this board a RD203 KF623 Featuring Intel 945G Chipset LGA775. Reason is I'm looking for a compatible bios. These are two simple questions if you know the answer great and thank you. If you don't do not worry about it.
