Why not ask the motherboard maker which is it? Or in the case of a brand name system, ask the manufacturer.
I'm trying to determine the manufacturer of my BIOS in order to download the beep codes. I read where you find this information when you enter setup. When I entered setup, it said I had Award Phoenix CMOS setup. It also said my BIOS revision was 5.13 and my Core Version was 6.0, if that helps. But yet, when I went to 2 different Web sites to download the beep codes, it lists separate codes for Award and separate codes for Phoenix. Can anyone enlighten me as to which manufacturer I need to download? Or if there is a Web site that offers beep codes for both Award and Phoenix?
