PCM-3350  User's Manual

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. Non-fatal error messages
usually appear on the screen along with the following instructions:

press <F1> to RESUME

Write down the message and press the F1 key to continue the
bootup sequence.

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 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 PCM-3350 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.
