Introduction
The MS-6198 Micro ATX VA3 mainboard is a high-performance
computer mainboard based on VIA® VT8 C694X chipset. The MS-6198 is
designed for the Intel® CeleronTM or Coppermine (FC-PGA) processor for
inexpensive business/personal desktop markets.
The Apollo Pro133A (VT8 C694X) is a Socket-370 system logic north
bridge with the addition of 133 MHz capability for both the CPU and
SDRAM interfaces. Apollo Pro133A may be used to implement both desktop
and notebook personal computer systems from 66MHz to 133MHz based on
Socket-370 (Intel Celeron processors). The primary features of the Apollo
Pro133A-North Bridge are: Slot-1 or Socket-370 CPU (Front Side Bus)
Interface (66 / 100 / 133MHz), SDRAM Memory Interface (66 / 100 /133MHz),
AGP Bus Interface (66MHz), PCI Bus Interface (33MHz), Mobile Power
Management.
The VT8 C686A PSIPC (PCI Super-I/O Integrated Peripheral
Controller) is a high integration, high performance, power-efficient, and high
compatibility device that supports Intel and non-Intel based processor to
PCI bus bridge functionality to make a complete Microsoft PC99-compliant

Hardware Installation
This chapter provides you with the information about hardware setup
procedures. During installation, be careful when handling the components
and follow the installation procedures properly. For some components,
installing it in a wrong orientation will cause it to become unstable.
Remember to use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CP . Match
Pin 1 with the white dot/cut
edge. Then, insert the CP .
It should insert easily.
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree

Central Processing Unit: CPU
The mainboard operates with Intel® CeleronTM/Coppermine
processor. The mainboard uses a CP socket called Socket 370 for easy
CP installation. The CP should always have a Heat Sink and a cooling
fan attached to prevent overheating.

• CPU Core Speed Derivation Procedure
If the CP Core/Bus ratio is already fixed, adjusting the SW1 will not
change the CP Core/Bus ratio. If the Core/Bus ratio is not fixed by
the CP , then you can adjust the SWI to change the Core/Bus ratio.
If CP Clock = 66MHz
Core/Bus ratio = 3.5
then CP core speed = Host Clock x Core/Bus ratio
= 66MHz x 3.5
= 233MHz

• Memory Population ules
1. Supports only SDRAM DIMM.
2. To operate properly, at least one 168-pin DIMM module must be
installed.
3. This mainboard supports Table Free memory, so memory can be
installed on DIMM1 or DIMM 2 in any order.
4. Supports 3.3 volt DIMM.

How to install a IMM Module
1. The DIMM slot has 2 Notch Keys VOLT and DRAM, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.
