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.

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.

Note: Always use a 5 volts SIMM with 70 ns

or above(Fast Page or EDO)

2-11

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.

CHAPTER 2 HARDWARE INSTALLATION

1. Make sure that the SIMM banks are using the same type and equal size
density memory.

2 . T o operate properly , at least two 72-pin SIMM module must be installed in

the same bank or one 168-pin DIMM module must be installed. The
system cannot operate with only one 72-pin SIMM module.

3. This mainboard supports Table Free memory so memory can be installed
on Bank 0 (SIMM1 + SIMM2), Bank 1 (SIMM3 + SIMM4), Bank 2
(DIMM1) or Bank3 (DIMM 2) in any order.

2.3-1 Turbo LED

The T urbo LED is used to monitor if the turbo switch is ON/OFF. You can
connect the Turbo LED from the system case to this pin. (See Figure 2.1)

2.3-2 Hardware Reset

Reset switch is used to reboot the system rather than turning the power ON/
OFF . A void rebooting while the HDD LED is lit. You can connect the Reset
switch from the system case to this pin. (See Figure 2.1)

2.3-3 Keylock

Keylock allows you to disable the keyboard for security purposes. You can
connect the keylock to this pin. (See Figure 2.1)

2.3-4 Power LED

The Power LED is always lit while the system power is on. You can connect
the Power LED from the system case to this pin. (See Figure 2.1)

2.3-5 Suspend Switch

The Turbo switch or Suspend switch allows the user to suspend the system
while not in use. It can be controlled by BIOS power management setup
switch function. You can connect the Turbo Switch from the system case to
this pin. (See Figure 2.1)

2.3-6 Speaker

Speaker from the system case is connected to this pin. (See Figure 2.1)

2.3-7 HDD LED

HDD LED shows the activity of a hard disk drive. Avoid turning the power
off while the HDD led is lit. You can connect the HDD LED from the system
case to this pin. (See Figure 2.1).

The BIOS first attempts to boot from
drive A: and then, if unsuccessful,
from hard disk C: and then from the

existence of the PS/2® mouse. If the

PS/2® mouse is installed, then IRQ12

table inside the VGA controller. In

order for the graphic controller to
generate the proper colors, the
graphic controller needs to know
what is in the palette of the VGA
controller. To do this , the non-VGA
graphic controller watches for write
access to the VGA palette registers
and snoops the data. In the PCI based
systems where the VGA controller is
on the PCI bus and a non-VGA
graphic controller is on the ISA bus,
the write access to the palette will
not show up on the ISA bus if the
PCI VGA controller responds to the
Writes. In this case, the PCI VGA
controller should not respond to the
write; it should only snoop the data
and permit the access to be
forwarded to the ISA bus. The non­VGA ISA graphic controller can
then snoop the data on the ISA bus.
Unless you have the above
situations, you should disable this
option.

A short description of this screen's items follows:

OnBoard FDC

Choose Enabled or Disabled. The default
setting enables the on-board FDC. If you
want to use off board FDC (i.e. ISA card),
then choose disabled.

IR Duplex Mode

If serial port2 mode is normal, then this

option is not available. If serial port2

mode is Ir function, then set as full or half

duplex mode.

OnBoard
Parallel Port

Choose LPT1 (378), LPT2 (278), LPT3

(3BC) or disabled for onboard parallel

port.

Parallel Port
Mode

Choose Extend or Normal. You can

set the Parallel Extend Mode only

when this item is set to Extended.

Parallel Port
DMA Channel

This option can be configured at

either the ECP mode or the ECP &

EPP mode. These two modes may

need to use one DMA channel.

Below is the procedure for using the

DMA channel when it is needed.

1.

Choose Extended for the Parallel Port

mode.

2. Choose ECP or ECP & EPP for the
Parallel Extended mode.

3. Choose DMA1 or DMA3 for the
Parallel Port DMA.

Parallel Port
IRQ

Choose IRQ 5 or 7. The interrupt of the
on-board parallel port is connected to the
chip set and is routed to the IRQ line by
the BIOS's program.

OnBoard IDE

Choose Both, Primary, Secondary, or

Disabled to enable or disable onboard

IDE channel ( primary and secondary)

function. Both: onboard IDE’s primary

Primary: only primary channel is enabled
and secondary channel is disabled.
Secondary: only secondary channel is
enabled and primary channel will be

secondary channels will be disabled.

Hard Disk Delay
