INTRODUCTION
The MS-5156 mainboard is a high-performance personal computer
mainboard. The mainboard supports the Peripheral Component Interconnect
(PCI) Local Bus standard and provides five 32-bit PCI bus slots.
The mainboard uses the highly integrated Intel® 83430TX chipset to support
the PCI/ISA and Green standards, and to provide the Host/PCI bridge. The
Intel® 82430TX chipset integrates all system control functions.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The MS-5156 mainboard operates with Intel® Pentium® processors/
Pentium® processors with MMX
TM
technology, Cyrix® 6x86/6x86L/
6x86MX and AMD® K5/K6 processors. It could operate with 2.8V to
3.52V processors. The mainboard 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 (JV2 - JV5) for setting the CPU voltage. The CPU
should always have a cooling fan attached to prevent overheating.

Cyrix® 6x86 processor uses PR to rate the speed of their processors based
on Intel® Pentium® processor core speed. For example PR150 (120MHz)
has 150MHz core speed of Intel® Pentium® processor but has 120MHz core
speed in Cyrix®. Cyrix® 6x86 processor should always use a more powerful

JFAN1 connector supports CPU cooling fan with +12V. It supports both two
and three pin head connector. When connecting the wire to the connector,
always take note that the red wire is the positive and should be connected to
the +12V. While JFAN2, JSFAN, and JPFAN system cooling fan with
+12V. It supports three pin head connector. When connecting the wire to
the connector, always take note that the red wire is the positive and should
be connected to the +12V, the black wire is Ground and should be
connected to GND, the yellow is the speed sensor. If your mainboard has
LM78 on board, you need to use a specially designed fan with speed sensor
to take advantage of LM78’s CPU fan control function.
Note: 1. JFAN2/JSFAN/JPFAN is used for CPU Cooling Fan Speed
Connectors.
(Reserved for LM78 System Hardware Monitor Option.)
2. Always consult vendor for proper CPU cooling fan.

2.2 PCI and ISA Slots
There are 5 PCI slots and 3 ISA slots. All PCI slots can be used as master.
But since the 1st and 5th PCI slots share the same bus master signal, only
one of these slots can be used as a master at a time; which means that if a
bus master card is installed in PCI slot 1, PCI Slot 5 can only accomodate a
slave card, and vice versa.
2-10
Note: 1 . You can only use a 3.3 V PCI Card, if the power supply you’re
using is an A TX power supply w/ 3.3V.
2. PCI Slot 1 to PCI Slot 5 IDSEL is AD_24(Device Num = 0DM) to
AD_28(Device Num = 11H) respectively.

2.3-1 Memory Bank Configuration
The mainboard provides four 72-pin SIMMs (Single In-Line Memory Module)
and two 168-pin DIMM(Double In-Line Memory) sockets. It supports six
memory banks for a maximum of 256MB memory . Each bank supports up to
64MB memory. Y ou can use SIMM from 4MB, 8MB, 16MB, 32MB, 64MB to
128MB, and DIMM from 8MB, 16MB, 32MB, 64MB to 128MB.
CHAPTER 2 HARDWARE INSTALLATION
2.3-2 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.

B. How to install DIMM Module
1. The DIMM slot has two keys marked “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.

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 (SIMM1 + SIMM2),(SIMM3 + SIMM4), (DIMM1), or (DIMM 2), in
any order .
4. If you use DIMM with 64Mbit SDRAM, then Bank2.3
(SIMM1+SIMM2) can not be use.
5 . DIMM and SIMM cannot be used at the same time. Only one kind can be
used at a time. If you want to use both of them you must use a 5V
DIMM.
