2.8.3 Clearing the CMOS
You need to clear the CMOS if you forget
your system password. To do this, shut
off the system power and short pins 2-3
of
JP12
for a few seconds. Reset the
jumper to normal setting by shorting pins
1-2.
Enter Setup to specify a new
password.
2.8.4 Disabling the Onboard Super I/O Controller
The board is preset by the manufacturer
with the onboard I/O controller enabled.
In case you wish to use an external I/O

onboard I/O before the external I/O card
functions. To disable, you need to reset
jumper
JP13
to 2-3.
2.8.5 Setting the ISA System Clock
Set the jumper

according to the
ISA system clock that your board
