Preface
About This Manual
This manual is written for system houses, PC technicians and
knowledgeable PC end users. It provides information for the instal-
lation and use of the SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2
motherboard, which supports the 75/90/100/120/133/150/166/180/
200/233 MHz Intel®Pentium®processor, Cyrix/IBM 5x86, 6x86,
AMD-K5, AMD-K6, MMXTM and future Pentium processors.
The Intel Pentium processor will take personal computer systems
to a new level of performance. The emergence of the PCI local bus
will also have a significant impact on PCs. Memory and I/O compo-
nents have also made significant strides in both performance and
integration, enhancing the CPU’s ability to move data quickly. Put-
ting these all together creates the next generation of PC systems.
Manual Organization
Chapter 1, Introduction, describes the features, specifications and
performance of the SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2
system board, provides detailed information about the chipset,
cache memory, main memory system, PC health monitoring, ACPI,
PC 98 and offers warranty information.
Refer to Chapter 2, Installation, for instructions on handling static-
sensitive devices, checking and/or configuring the jumpers for
manufacturing. Read this chapter when you want to configure CPU
and voltage settings, install or remove SIMM/DIMM memory mod-
ules, and to mount the system board in the chassis. Also refer to
this chapter to connect the floppy and hard disk drives, enhanced
IDE configurations, Infrared, USB, parallel port, serial ports, as well
as the cables for the power supply, reset cable, Keylock/Power LED,
speaker, overheat fan and keyboard.

If you encounter any problem, please see Chapter 3, Troubleshoot-
ing, which describes troubleshooting procedures for video, memo-
ry, and the setup configuration stored in memory. Instructions are
also included on contacting a technical assistance support repre-
sentative and returning merchandise for service and the BBS# for
BIOS upgrading.

Introduction
1-1 Overview
SUPER P5MMA98, P5MMS98, P5MMA2, P5MMS2 are PC 98-ready
motherboards designed to maximize user satisfaction and simplic-
ity in managing the personal computer. The four motherboards
support Intel®Pentium® 233/200/180/166/150/133/120/100/90/75
MHz, Cyrix/IBM 5x86, 6x86, AMD-K5, AMD-K6 and MMXTM processors.
They are based on Intel's advanced 430TX chipset to provide the
best possible platform for multimedia applications. They support
Synchronous DRAM (SDRAM), Concurrent PCI, and 33 MB/s Ultra
DMA for fast disk reads and writes.
All motheboards support PC Health Monitoring features including
CPU fan auto-off in sleep mode, CPU overheat alarm and LED,
hardware BIOS virus protection, and a switching voltage regulator
for the CPU core. SUPER P5MMA98 and P5MMS98 have an LM78
chip on-board which support additional PC Health Monitoring fea-
tures, including seven voltage monitors, fan status monitors with
firmware/software control on/off, CPU/chassis temperature moni-
tors, Intel LANDesk®Client Manager support, and system resource
alert. A chassis intrusion detection prevents system tampering.
ACPI/PC 98 features include Microsoft®OnNow power manage-
ment, with a slow blinking LED to indicate the system is in the
sleep state, BIOS support for the USB (Universal Serial Bus) key-
board, and real time clock wake-up alarm. The motherboards pro-
vide a main switch override mechanism, and external modem ring-
on if the system is in a SoftOff state.
SUPER P5MMA98 and P5MMA2 are ATX size (12" x 8.3"). SUPER
P5MMS98 and P5MMS2 are baby AT size (11" x 8.3"). All support up
to 256 MB of FPM, EDO, or SDRAM, with 512 KB pipelined burst
SRAM or L2 cache, using two 168-pin unbuffered 3.3 V DIMM sock-

ets and four 72-pin 5 V SIMM sockets. They include four PCI and
four ISA slots with two EIDE, one floppy, ECP/EPP parallel port, PS/
2 mouse and keyboard connectors, two 16550-based serial ports,
two USBs, and a fast IR port. SUPER P5MMS98 and P5MMS2 sup-
port 2 Mb/s back-up tapes.

For maximum flexibility, all four motherboards support AT or ATX-
type power supply. The AMI WinBIOS has a 1 Mb flash memory for
convenient BIOS upgrade. The BIOS supports Advanced Power
Management (APM), Plug and Play, and PC health management.
