1.2.2 CMOS RAM and CMOS RAM Extension
CMOS RAM provides 64 bytes of storage. Fifty 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. An 8KB
(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 restore configuration from the system programs
stored on the hard disk drive.
If the configuration uses the default settings, run automatic
configuration from the system programs stored on the hard disk drive.
