Note
Before you clear the CMOS, you have to first turn the power off (including the +5V
standby power). Otherwise, your system may work abnormally or malfunction.
(11) J1 & J2 Headers:
There are two headers to use for selecting
the functions for the audio CODEC and/or
the AMR card. Please refer to the table
below for the proper settings.
For example, if you want to use the onboard
audio CODEC, choose the “AC97” settings.
If you want to use the modem CODEC card
insertion on the AMR slot, then choose the “MC 97” setting. If you want both to work,
choose the “AC 97 & MC 97” setting.
(12) JP1 Header: AMR Function Selection
This header can select whether the AMR
card insertion on the AMR slot is primary or
secondary. When you don’t want to use the
onboard audio CODEC, you have to set JP1
at open. The default setting is short.
Remember that only when using an MC 97
card should you select the JP1 as open.
Otherwise, leave it selected as short.
