3.1 System Test and Initialization
The ASDM-L-CFS module uses certain routines to perform testing and initialization
during the boot up sequence. If an error, fatal or non-fatal, is encountered, the module
will output a few short beeps or display an error message. The module 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 module 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 is reset by the Clear CMOS Jumper (See Ch. 2)
3. The CMOS memory has lost power and the configuration information has been
erased.
The ASDM-L-CFS CMOS memory has an integral lithium battery backup for data
retention. However, you will need to replace the battery unit when it runs down.
