and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.
Notice 2

Introduction
The MS-5149 is a high-performance personal computer mainboard. This
mainboard supports Intel® Pentium® processors/Pentium® processor with
MMX™ technology , Cyrix® 6x86/6x86L/6x86MX processors and AMD® K5/
K6 processors.The system board supports the Peripheral Component
Interconnect (PCI) Local Bus standard and provides four 32-bit PCI bus
master slots.
It has a cache subsytem that can be configured for 256K or 512 K cache
memory to improve overall throughput.
The system board uses the highly integrated Intel® 83430VX Chipset to
support the PCI/ISA and Green standards, and to provide the Host/PCI
bridge. The Intel® 82430VX chipset integrates all system control functions.

Hardware Installation
2.1 Central Processing Unit: CPU
The MS-5149 motherboard operates with Intel® Pentium® processors/
Pentium® processor with MMX technology, Cyrix® 6x86/6x86L/6x86MX,
and AMD® 5K86/K6 processors. It could operate with 2.8V to 3.52V
processors. The motherboard provides a 321-pin ZIF Socket 7 for easy CPU
installation, a DIP switch (SW1) to set the proper speed for the CPU and a
Jumper block (JV1 - JV4, JV5) for setting the CPU voltage. The CPU should
always have a cooling fan attached to prevent overheating.
2.1-1 CPU Installation Procedure
1 . Pull the lever sideways away
from the socket. Then raise
the lever up to a 90-degree
angle.
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 CPU. Match
Pin 1 with the white dot/cut
edge. Then insert the CPU.
It should insert easily.

CHAPTER 2 HARDWARE INSTALLATION
1. The 4 CPU clock frequencies that the system supports are 50 MHz,
55MHz, 60MHz and 66.6MHz (To adjust SW1 pin 1, 2 , and 3). See the
following chart to set the different Host Clock Frequencies.
1 2 3 CLOCK
ON ON OFF 50MHz
OFF O N OFF 55MHz
ON OFF OFF 60MHz
OFF OFF OFF 66.6MHz
SW1 CPU
2 . The DIP Switch SW1 (4, 5 and 6) is used to set the Core/Bus (Fraction)
ratio of the CPU. The actual core speed of the CPU is the Host Clock
Frequency multiplied by the Core/Bus ratio. For example:
If CPU Clock = 66.6MHz
Core/Bus ratio = 3/ 2
then CPU core speed = Host Clock x Core/Bus ratio
= 66.6MHz x 3/2
= 100MHz
3. The PCI Bus Clock is the CPU Clock Frequency divided by 2.

2.2 Memory Installation
2.2-1 Memory Bank Configuration
The system board supports a maximum of 128M of memory . It provides four
72-pin SIMMs (Single In-Line Memory Module) and two 168-pin DIMM
sockets. This board supports 4 banks wherein each bank supports memory
ranging from 4MB to 32MB. A Bank always has a pair of SIMM or a single
DIMM. Each bank supports 4M, 8M, 16M and 32M. The 2MB is the
minimum and the 16MB is the maximum for one 72-pin single sided memory
module.
W arning! SIMM Socket 1-4 power level is 5 volts. DIMM Socket 1 & 2
power level is 3.3 V/5V. W e suggest not to install both the SIMM
& DIMM at the same time. But if you want to install both SIMM
& DIMM slot, you must use a 3.3 volt DIMM with 5 volt I/O
signal tolerance or use a full 5 volt DIMM module. Otherwise it
may cause damage to the DIMM.

CHAPTER 2 HARDWARE INSTALLATION
2.2-2 Memory Installation Procedures:
1. The SIMM slot has a “Plastic Safety
Tab” and the SIMM memory module
has a “Notched End”, so the SIMM
memory module can only fit in one
direction.
2. Insert the SIMM memory modules into
the socket at 45-degree angle. Then
push into a vertical position so that it
will snap into place.
3. The Mounting Holes and Metal Clips
should fit over the edge and hold the
SIMM memory modules in place.
A. How to install a SIMM Module

Note: Always use a 5 volts SIMM with 70 ns
or above(Fast Page or EDO)

CHAPTER 2 HARDWARE INSTALLATION
B. How to install a DIMM Module
1. The DIMM slot has a two key mark “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. Close the plastic clip at the side of the DIMM slot.
Single Sided DIMM
Double Sided DIMM
2-12
Note: If you have installed SIMM and DIMM at the same time, you must
use a 3.3 volt DIMM with 5 volt I/O signal tolerance or a full 5 volt
DIMM module (EDO, FP or SDRAM). Look for J2 to select the
DIMM voltage.
