Embedded Controller AEC-6612 Rev. B
3.1 System Test and Initialization
These routines test and initialize board hard ware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or se e 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-fat al e rrors.
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 info rmation in memory.
There are three situations in which you will nee d to change the
CMOS settings:
1. You are starting your syste m 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 Rev.B CMOS memory has an integral lithium
battery backup for dat a retention. However, you will need to replace
the complete unit when it finally runs down.
