CMOS Clear
Refer to Table 2-12 for instructions
on how to clear the CMOS. For an
ATX power supply, you need to
completely shut down the sys-
tem, then use JBT1 to clear the
CMOS. Do not use the PW_ON
connector to clear the CMOS. A
second way of resetting the CMOS
contents is by depressing the <Ins>
key, then turning on the system
power. Release the key when the
power comes on.
ATX Serial Ports
ATX serial port COM1 is located on
J20 and serial port COM2 is located

nitions.
