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.
