ATC6430M Mainboard Chapter 1 System Features

1-3-3 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.

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.
