The Baby AT form factor

system board is designed to fit

into an ATX form factor chassis.

It is equipped with ATX and AT

power supply connectors. Set

JP2 according to the type of

power supply installed.

ATX Power Supply

If you are using an ATX power

supply, set pins 1 and 2 to On

then set jumper JPP according

to the method you would like the computer to power-on/off.

Important:

If JPP pins 2 and 3 is set to On, that is using the AC power to

power on/off the computer, make sure JP2 pins 1, 2 and 3 is

set to Off. Refer to the next section (Jumper Settings for ATX

Power-On/Off Select) for more information.

AT Power Supply
