A jumper may be installed into V1[9-10] to erase the contents of the CMOS RAM and the Real-
Time Clock. The jumper should be installed when the EPM-32 is turned off, left installed for a
minimum of three seconds and removed before powering on the EPM-32.
CMOS Setup Defaults
The EPM-32 permits users to modify the CMOS Setup defaults. This allows the system to boot
up with user-defined settings from cleared or corrupted CMOS RAM, battery failure or battery-
less operation. All CMOS setup defaults can be changed, except the time and date. The CMOS
Setup defaults can be updated with the Flash BIOS Update (FBU) Utility, available from the
If the CMOS Setup default settings make the system unbootable and prevent you from entering
CMOS Setup, remove the System BIOS Selector jumper and reboot the system. The master
system BIOS will allow the system to boot using its own DMOS Setup defaults.

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.
