The CMOS RAM is powered by an onboard button cell battery.

Note:	If you intend to update CMOS RAM data, you have
	to click on “DEL” within two seconds of the “CMOS
	checksum error....” display screen message appear-
	ing. Then enter the “Setup” screen to modify the
	data.
	If the “CMOS checksum error....” message appears
	again and again, please check to see if you need to
	replace the battery in your system.
