AMR and AC’97 CODEC Controller
AMR slot and AC’97 CODEC are integrated into the Mainboard to enable audio and
modem playback.
AMR (Audio/Modem Riser) slot is mounted on board to connect riser board with
Audio and/or Modem CODEC (AMC/AC/MC Adapters). The AMR specification
developed by Intel provides a mechanism for AC’97 codes to be on a riser card.
To enable the onboard AC’97 CODEC, set JP9 pin 2-3 closed. And in such way,
you can further plug a riser board with Modem CODEC to the AMR slot. Otherwise,
disabling onboard AC’97 CODEC by setting JP9 1-2 closed, you can plug a riser
board with Audio/Modem CODEC to the AMR slot.
See Page A for AMR location on 6430M Mainboard.
1-3-4 Software Power Off Control
This mainboard supports Software Power Off Control feature through the SMM code
in the BIOS under Windows 95/98, and MS-DOS operation system environment.
First, you should connect the power switch cable to the connector “PS-ON” on the
mainboard. In the BIOS screen of POWER MANAGEMENT SETUP’, choose “User
Define” (or “Min. Power Saving” or “Max. Power Saving”) in ‘Power Management’.
In Windows 95/98, if you want to power off the system, you just need to choose
“shutdown the computer?” in the “Shut Down Windows” of Windows 95/98. Then the
system power will be off directly, and stay at the stand-by status. If you want to restart
the system, just press the power switch button..
Note : If you are going to leave your system idle for several days, we suggest you
use hardware power off to shut down your system.
