3.1 System Test and Initialization

These routines test and initialize board hardware. If the routines

encounter 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

boot up sequence with non-fatal errors.

System configuration verification

These routines check the current system configuration against the

values stored in the CMOS memory. If they do not match, the

program outputs an error message. You will then need to run the

BIOS setup program to set the configuration information in memory.

There are three situations in which you will need to change the

CMOS settings:

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

information has been erased.

The AEC-6612 CMOS memory has an integral lithium battery

backup for data retention. However, you will need to replace the

complete unit when it finally runs down.
