Chapter 1 Motherboard 7KT400A
The 7KT400A motherboard is an integration of AMD
Athlon/Duron CPU in Socket 462 packaging and the North
Bridge VIA KT400A (VT8377A) supporting 100/133/166
MHz Front Side Bus.
North Bridge KT400A on board also supports DDR 200/
266/333/400 SDRAMs, while the South Bridge VT8235 pro-
vides stable supports of ULTRA ATA 133, 6-channel Audio
playback and USB 2.0/1.1 interface.
The resulting architecture will provide an ideal multi-task
environment to support operating systems such as MS-DOS,
Windows, Windows NT , Windows ME, Windows 2000, Novell,
OS/2, Windows 95/98, Windows 98SE, Windows XP, UNIX,
Liunx, SCO UNIX etc. This user-friendly manual is to de-
scribe in detail how to install, configure and use this
motherboard with drivers and BIOS setup illustrations.

BIOS
The motherboard operates with Socket 462 for AMD AthlonTM
and DuronTM processor. The CPU should always have a Heat Sink
and cooling fan attached to prevent overheating.
CPU Installation Procedures for Socket 462
1. Pull the lever sideways away from the socket then raise the
lever to a 90-degree angle.
2. Locate Pin 1 in the socket and look for the white dot or cut edge
in the CPU. Match Pin 1 with the white dot/cut edge then
insert the CPU.
3. Press the lever down to complete the installation.
4. Make sure the spec of the cooling fan is good enough.
5. Please lock the fan on CPU very carefully, or you will damage
the resistor array even circuit line on the mainboard.
