BIOS Setup
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. This special information is then
stored in battery-backed RAM so that it retains the Setup information when the
power is turned off.
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.
The PhoenixBIOS has been customized by adding important, but
non-standard, features such as password protection as well as special support
for detailed fine-tuning of the chipset controlling the entire system.
The rest of this chapter is intended to guide you through the process of
configuring your system using Setup.
