1.5.1 CMOS Memory Clearing Header and Backup
Battery
The time to clear the CMOS memory occurs when (a) the CMOS data
becomes corrupted, (b) you forgot the supervisor or user password
preset in the BIOS menu, (c) you are unable to boot-up the system
because the CPU ratio/clock was incorrectly set in the BIOS menu, or (d)
whenever there is modification on the CPU or memory modules.
This header uses a jumper cap to clear the CMOS memory and have it
reconfigured to the default values stored in BIOS.
