The BIOS-Related Jumper
Jumper JCMOS1: Clear CMOS Memory
JCMOS1 is a jumper switch, but it does not set a hard-
ware configuration setting. The BIOS CMOS Setup Utility
creates a system configuration record that is stored in
CMOS memory in the real-time clock chip. If the configu-
ration record data becomes corrupted or is destroyed, or
if the CMOS Setup Utility settings are changed to an un-
usable configuration, the motherboard may not run prop-
erly or at all. JCMOS1 provides a means to delete the
configuration data stored in CMOS memory and reset the
configuration to the CMOS Setup Utility’s Optimized De-
faults.
Follow this procedure to clear CMOS memory. If neces-
sary, refer to the motherboard diagram and key in Chap-
ter 2 for the jumper location.
1. Turn off and unplug the system. Remove the system
housing cover (see documentation if necessary).
2. Set JCMOS1 to the Clear CMOS position by placing
the jumper cap over pins 2 and 3 for one minute.
3. Return the jumper cap to the Normal position.
4. Replace the system housing cover, plug in the sys-
tem and turn it on.
5. Run the CMOS Setup utility and load the Optimized
Defaults. You can then enter any custom settings
you require.
6. Save the settings as you exit the program and restart
the computer.
The system should now operate normally.
