CMOS Setup Utility

You never deal directly with the many BIOS routines, but instead interact

with themonly peripherally through theCMOSsetup utility.Motherboard

manufacturers don’t actually write their own BIOS routines. Instead, they buy

BIOS from third-party BIOS makers; among the largest makers are American

Megatrends (AMI) and Phoenix Technologies. The latter produces BIOS under

both the Phoenix and Award brands. A great deal of uniformity exists among

brands of BIOS software, however, so from a technician’s point of view, there’s

not all that much of a difference between them.
