3.1 System Test and Initialization
The EPIC-KBS9-PUC board uses certain routines to 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 routines check the current system configuration
stored on the CMOS memory and BIOS NVRAM. If the system configuration is not
found or a system configuration data error is detected, the system will load the
optimized default and re-boot with this default system configuration automatically.
There are four situations in which you will need to setup System Configuration:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The system configuration is reset by Clear-CMOS jumper
4. The CMOS memory has lost power and the configuration information has been
erased.
The EPIC-KBS9-PUC CMOS memory has an integral lithium battery backup for data
retention. You will need to replace the complete unit when it runs down.
