3.1 System Test and Initialization
The PICO-EHL4 uses certain routines to perform testing and initialization during the
boot up sequence. If an error, fatal or non-fatal, is encountered, the system will output
a few short beeps or display an error message. The board can usually continue the
boot up sequence with non-fatal errors.
The system configuration verification routines check the current system configuration
against the values stored in the CMOS memory and BIOS NVRAM. If a system
configuration is not found or an error is detected, the system will load the default
configuration and reboot 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 was reset by the Clear CMOS jumper
4. The CMOS memory has lost power and the configuration information has been
erased
The PICO-EHL4 CMOS memory has an integrated lithium battery backup for data
retention. The battery must be replaced when it runs down.
