CMOS Clear
Refer to Table 2-14 for instructions
on how to clear CMOS. For an ATX
power supply, you need to com-
pletely shut down the system,
and then use JBT1 to clear CMOS.
Do not use the PW_ON connector
to clear CMOS. A second way of
resetting the CMOS contents is by
pressing the <Ins> key and then
turning on the system power. Re-
lease the key when the power comes
on.
ATX Serial Ports
ATX serial port COM1 is located
on J20 and serial port COM2 is
located on J21. See Table 2-13
for pin definitions.
Wake-On-LAN
The Wake-On-LAN connector is lo-
cated on WOL. Refer to Table 2-16
