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.  
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

1-3-8 Wake-On-LAN  
The remote Wake-On-LAN (WOL) mode of operation is a mechanism that uses  
Advanced Micro Device Magic Packet technology to power on a sleeping workstation  
on the network. This mechanism is accomplished when the LAN card receives a  
specific packet of information, called a Magic Packet, addressed to the node on the  
network. For additional protection, Secure ON is an optional security feature that can  
be added to the Magic Packet that requires a password to power on the sleeping  
workstation. When LAN card is in remote Wake-On-LAN mode, main system power  
can be shut down leaving power only for the LAN card and auxiliary power  
recondition.  
The LAN card performs no network activities while in the remote Wake-On-LAN  
mode of operation. It only monitors the network for receipt of a Magic Packet. If a  
Magic Packet is addressed to the LAN card on the network, the LAN card wake up the  
system. If the Secure ON feature has been enabled, the password added to the Magic  
Packet is also verified prior to waking up the system.  
You should select two kinds of PCI Ethernet cards with WOL function. One is  
Intel and the other is with PME signal supporting. And you can set “PCI PME#

Function” enabled through “ Power Management Setup” from the BIOS setup screen.  
Caution: For Wake-On-LAN, the +5V standby line for the power supply should be  
capable of delivering +5V ± 5% at 720mA. Failure to provide adequate standby current  
when implementing Wake-On-LAN will damage the power supply.

ATC6430M Mainboard  
Chapter 3 Award BIOS Setup  
3-1-2 UPDATE MICROCODE API  
Intel also provides MICROCODE API (Applications Programming Interface) for  
mainboard user to update data block in BIOS quickly and easily. (You can find this  
utility in the All-In-One CD in the mainboard package).  
The BIOS code on the mainboards contains data that is specific to each silicon  
stepping of the processor. Integrators must ensure that this BIOS stepping data  
matches the used processor stepping. When the BIOS does not contain stepping data  
that matches the processor stepping, integrators must update the data in the BIOS  
before shipping the system. Historically, the systems have been updated by replacing  
the entire BIOS with a new revision of BIOS that contains the correct stepping data.  
Intel’s BIOS update API allows just the stepping data within the BIOS to be  
updated as needed. Mainboards that contain a BIOS with the Intel-defined BIOS  
update API can be quickly and easily updated, if required, without obtaining a  
complete BIOS upgrade. Using this utility, integrators can easily verify that the correct  
stepping data is present in all mainboards. However, if the stepping data requires to be  
updated, the mainboard BIOS must contain the Intel-defined BIOS update API,  
otherwise a complete BIOS upgrade is required from the mainboard vendor.  
Since API program can only be executed under DOS Real Mode, you must enter  
Real Mode first and load the API program to Drive C.  
To load the program to C by following steps:  
(1) Type “ md c:\ api ” and press Enter. Directory “api” is made in Drive C now.  
(2) Insert the Driver/Utility CD into CD ROM Drive E.  
(3) Then type “ copy e:\api\*.* c:\api ” and press Enter.  
(API program is loaded to Drive C now.)  
(4) Type “ C:\ api \checkup ” to execute this program.  
The main menu should now be displayed with the following four options :  
1) Check and load update  
2) Specify stepping data file [current : pep.pdb]  
3) Help  
4) Quit without loading update  
Select 1 to know the stepping filename, select 2 to load right patch code, then  
select 1 to update proper patch code. Now, the screen will show the message “please  
remove the CD from CD-ROM drive”. Then cold boot (mechanical power off) system  
to continue. For more information, please refer to “CHECKUP.HLP“ file.

SDRAM CAS Latency Time When synchronous DRAM is installed, the number of  
clock cycles of CAS latency depends on the DRAM timing. The choices: 2,3. “2”  
gives faster performance and “3” gives more stable performance.  
SDRAM Cycle Time Tras/Trc Select the number of SCLKs for an access cycle.  
“5/7” gives faster performance and “6/8” gives more stable performance.  
SDRAM RAS-to-CAS Delay This field lets you insert a timing delay between the  
CAS and RAS strobe signals, used when DRAM is written to, read from, or  
refreshed. “2” gives faster performance and “3” gives more stable performance. This  
field applies only when synchronous DRAM is installed in the system.  
SDRAM RAS Prechage Time If an insufficient number of cycles is allowed for the  
RAS to accumulate its charge before DRAM refresh, the refresh may be incomplete  
and the DRAM may fail to retain data. This field applies only when synchronous  
DRAM is installed in the system.  
System BIOS Cacheable Selecting Enabled allows the caching of the system BIOS  
ROM area, resulting in better system performance. However, if any program writes to  
this memory area, a system error may result.  
Video BIOS Cacheable Selecting Enabled allows the caching of the video BIOS  
ROM area, resulting in better system performance. However, if any program writes to  
this memory area, a system error may result.
