System Test And Initialization - Asus AAEON uCOM-ADN User Manual

System Test and Initialization

The module 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 in the CMOS memory and BIOS NVRAM. If a 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:
You are starting your system for the first time.
⚫
You have changed the hardware attached to your system.
⚫
The system configuration is reset by Clear-CMOS jumper
⚫
The CMOS memory has lost power and the configuration information has been
⚫
erased.
The uCOM-ADN 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.
