Chapter 9 Award BIOS Setup

The PPC-L126 comes with an Award BIOS chip that contains the ROM

setup for your system. This chip serves as an interface between the pro-

cessor and the rest of the mainboard's components. This chapter explains

the information shown in the setup program and tells you how to modify

the settings according to your system configuration. Some items are not

explained, because it is recommended that users don’t change them.

9.1 System test and initialization

These routines test and initialize board hardware. If the routines encoun-

ter an error during the tests, you will either hear a few short beeps or see

an error message on the screen. There are two kinds of errors: fatal and

non-fatal. The system can usually continue the booting with non-fatal

errors. Non-fatal errors are usually shown with the following instructions:

press <F1> to RESUME

Write down the message and press the F1 key to continue booting.

9.1.1 System configuration verification

These routines check the current system configuration against the values

stored in the board’s CMOS memory. If they do not match, the program

outputs an error message. You will then need to run the BIOS setup pro-

gram to set the configuration information in memory.

The CMOS settings need changing in the following situations:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The CMOS memory has lost power and the configuration informa-

tion has been erased.

The PPC-L126 CMOS memory has an integral lithium battery backup.

The battery backup should last ten years in normal service, but when it

finally runs down, you will need to replace the complete unit.

Note: Values for the various setup items that appear on

your screen (including default values) may not be the

same as those shown in this chapter. This is because

the BIOS is revised and updated from time to time. If

in doubt, check Advantech's website for the latest

BIOS versions and related information.
