KM400A Series
Chapter 1. Getting Started
Introduction
Congratulations on choosing the KM400A series mainboard! The series include KM400A PRO-1394,
KM400A PRO, and KM400A. These are based on the VIA®KM400A Northbridge and the VIA®
VT8237 Southbridge chipset. It supports AMD®AthlonTMXP/ AthlonTM/ DuronTM/ BartonTM
Processors with a FSB (Front Side Bus) frequency of 200/ 266/ 333/ 400 MHz.
The KM400A Series provides 2 DIMM sockets using 184 pin DDR SDRAM with a total capacity of
up to 2 GB. You can install unbuffered & non-ECC DDR400/333/266/200(PC3200/2700/ 2100/1600)
SDRAM. They support 64 bit single channel memory bus with a total capacity of up to 2 GB.
The KM400A Series provides one 8X/4X AGP Slot that use 1.5V AGP cards only.
The KM400A Series include built in IDE facilities that support Ultra ATA 33/ 66/ 100/ 133 Ultra
6-0/ DMA 2-0 and PIO 4-0 modes. The KM400A Series also include built in SATA facilities that
support Serial ATA 150 and support SATA RAID 0 or 1.
The KM400A Series also comes with an AC’97 Sound Codec (VT1616) which supports high quality
6 channel audio (super 5.1 Channel Audio Effect). It also supports Sony/ Philips Digital Interface
(S/PDIF).
The KM400A Series also comes with 8 USB 2.0 ports and the KM400A PRO-1394 comes with two
IEEE 1394 ports (optional).
The KM400A Sereis also include CPU Over Temperature Protection (OTP). When CPU temperature
rises above normal values, the system will automatically shut down to protect your system from
overheating. But the OTP is only functional when using an Athlon XPTM or BartonTM CPU.
The KM400A Series include an infrared header. The KM400A PRO-1394/ KM400A PRO also
provides a back panel LAN port. More information in the section of Back Panel Configuration.
The company’s 3 Year Limited Warranty for this product covers both labor costs and replacement
parts during the 1st year. Only labor costs are covered during the 2nd and 3rd years (replacement
parts will be charged during the 2nd and 3rd years).
All of the information in this manual only for reference. This specification is subject to change
without notice.

Hardware Installation
This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.
CPU Processor Installation
This mainboard supports AMD®processors using a Socket A. Before building your system, we
suggest you visit the AMD®website and review the processor installation procedures.
http://www.amd.com
CPU Socket A Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.
2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near to the end of
the lever. Match the corner on the CPU with the pin-1 receptor on the socket and lower the CPU
onto the socket. The bottom of the CPU should be flush with the face of the socket.
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps on
the fan to attach it to the socket. Finally, extend the power cable from the fan and insert it onto the
CPUFAN adapter.
Attention: Before starting the system
Please check the installation completely before starting the
system. Verify that the heatsink is properly installed and make
sure the CPU fan is working. Overheating can damage the CPU
and other sensitive com
p
onents.

FAN Headers
Three power headers are available for cooling fans, which play an important role in maintaining the
ambient temperature in your system.
The mainboard contains 2 sockets, which use 184 pin DDR SDRAM with a total memory capacity of
up to 2 GB. You can install unbuffered & non-ECC DDR400/ 333/ 266/ 200 (PC3200/ 2700/ 2100/
y bus with a total memory capacity of up to 2

GB.
Attention
This system has a BIOS configuration feature that issues a warning
(during POST) when the CPU fan is not plugged in or is not
functioning. In order to make use of this feature. You must make sure
that the CPU power cable is attached specifically to the “CPUFAN”
header. The BIOS configuration option is described in the “Hardware
Monitor” section of the BIOS Setup Utility Chapter.

RAM Module Installation:
1. Pull the white plastic tabs on each side of the slot away from the slot.
2. Match the notch on the button of the RAM module with the corresponding pattern in the DIMM
slot. This ensures that the module is inserted properly.
3. Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the module
snaps into place.
4. Repeat steps 1、2 and 3 for the remaining RAM modules.
