Chapter 2. BIOS Setup
Introduction
This section describes PHOENIX-AWARD™ BIOS Setup program which resides in the BIOS firmware. The
Setup program allows users to modify the basic system configuration. The configuration information is
then saved to CMOS RAM where the data is sustained by battery after power-down.
The BIOS provides critical low-level support for standard devices such as disk drives, serial ports and
parallel ports. As well, the BIOS controls the first stage of the boot process, loading and executing the
operating system.
The PHOENIX-AWARD TM BIOS installed in your computer system’s ROM is a custom version of an industry
standard BIOS. This means that it supports the BIOS of Intel ® based processors.
This version of the PHOENIX-AWARD TM BIOS includes additional features such as virus and password
protection as well as special configurations for fine-tuning the system chipset. The defaults for the BIOS
values contained in this document may vary slightly with the version installed in your system.
