Chapter 3. BIOS Setup
The ROM chip of your PL-80470 board is configured with a customized Basic
Input/Output System (BIOS) from AMI BIOS. The BIOS is a set of
permanently recorded program routines that give the system its fundamental
operational characteristics. It also tests the computer and determines how
the computer reacts to instructions that are part of programs.
The BIOS is made up of code and programs that provide the device-level
control for the major I/O devices in the system. It contains a set of routines
(called POST, for Power-On Self Test) that check out the system when you turn
it on. The BIOS also includes BIOS setup program, so no disk-based setup
program is required CMOS RAM stores information for:
Date and time
Memory capacity of the appliance
Type of display adapter installed
Number and type of disk drives
The CMOS memory is maintained by battery installed on the PL-80470 board.
By using the battery, all memory in CMOS can be retained when the system
power switch is turned off. The system BIOS also supports easy way to
reload the CMOS data when you replace the battery of the battery power lose.
3.1 Quick Setup
In most cases, you can quickly configure the system by choosing the following
main menu options:
1. Choose “Exit”
“Load Optimal Defaults” from the main menu. This loads
