This chapter discusses the PhoenixBIOS Setup program built into the ROM BIOS. The
Setup program allows users modifying the basic system configurations according to their
requirements.
The BIOS is the Basic Input / Output System used in all IBM® PC, XT™, AT®, and PS/2®
compatible computers. The PhoenixBIOS flash chip stores the system parameters, such
as type of disk drives, video displays, etc. in the CMOS. When the computer is turned
off, a back-up battery provides power to the BIOS flash chip, enabling it to retain system
parameters. Each time the computer is powered-on the computer is configured with the
values stored in the BIOS ROM by the system BIOS, which gains control at boot-up.
The PhoenixBIOS installed in your computer system’s ROM (Read Only Memory) is a
custom version of an industry standard BIOS. The BIOS provides critical low-level support
for standard devices such as disk drives and serial and parallel ports.
