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
controller, you need to disable the
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 JP14 according to the
ISA system clock that your board
supports. Refer to the figure on the right
for the correct jumper setting.
