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
