1.2.2 CMOS RAM and CMOS RAM Extension
The CMOS RAM provides 64 bytes of storage. The first 50 bytes are used to
store system-configuration and security information. The real-time clock
uses the remaining 14 bytes to track the date, time, and battery level. A
2KB (KB = 1024 bytes) CMOS RAM extension stores additional configuration
and system-status information.
The data stored in the CMOS RAM and CMOS RAM extension is kept active by
the battery when the system is powered-off. If the stored data is lost
due to a depleted or removed battery, the data can be restored using one
of the following methods:
If the user has a customized configuration that uses settings other
than the default, run the restore configuration program on the user's
backup copy of the Reference Diskette.
If the configuration uses the default settings, run the automatic
configuration program on the Reference Diskette.
