CMOS RAM

CLEARING CMOS RAM

Jumper V1 can be moved to position [1-2] for 30 seconds to erase the contents of the CMOS RAM. Be sure to move the jumper back to position [2-3] for normal operation.

Note: Operation of the board with jumper V1 in the erase position [1-2] is not supported or recommended.

DEFAULT CMOS RAM SETUP VALUES

After the CMOS RAM is cleared, the system will load default CMOS RAM parameters the next time the board is powered on. The default CMOS RAM setup values will be used in order to boot the system whenever the main CMOS RAM values are blank, or when the system battery is dead or has been removed from the board.

Real Time Clock

The EPM-4 features a year 2000 compliant, battery-backed 146818 compatible real time clock/calendar chip. Under normal battery conditions, the clock will maintain accurate timekeeping functions during periods when the board is powered off.

SETTING THE CLOCK

The CMOS Setup utility (accessed by pressing the [DEL] key during a system boot) can be used to set the time/date of the real time clock.
