CHAPTER 1 INTRODUCTION
1-1
The MICRO ATX ZX mainboard is a high-performance personal computer
mainboard based on the Intel®Pentium®II/Pentium®III/CeleronTM processor.
This mainboard combines leading edge nVIDIA Riva TNT2 M64 technology
in graphics and Creative®ES1373 PCI technology in audio. The Intel®
Pentium®II/III/CeleronTMprocessor supports MMXTM (Multimedia Exten-
sion) technology.
The mainboard uses the highly integrated Intel®82443ZX AGP chipset to
support the PCI/ISA and Green standards, and to provide the Host/AGP
bridge. The Intel®82371EB chipset integrates all system control functions
such as ACPI (Advanced Configuration and Power Interface). The ACPI
provides more Energy Saving Features for the OSPM(OS Direct Power
Management) function. The Intel®82371EB chipset also improves the IDE
transfer rate by supporting Ultra DMA/33 IDE that transfers data at the rate
of33MB/s.
The mainboard also supports the System Hardware Monitor Controller as an
optional function. Its functions include: CPU /power supply/chassis fan
revolution detect, CPU/system voltage monitor, system temperature monitor,
and chassis intrusion detect(optional).

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
Step 1: Install the Retention Mechanism.
Attach the Retention Mechanism to the Mainboard. Push the Plastic
lock to secure the Retention Mechanism into the mainboard.
Secure the processor by
pulling up the Retention
Mechanism Processor
Lock
Insert the processor
like inserting a PCI or
an ISA card
To release the
processor, push the
Retention Mechanism
Processor lock down
Step 2: Install the Processor.
Insert the Processor like inserting a PCI or an ISA card.
Step 3: Lock the Processor.
Lock the processor by pulling up the Retention Mechanism proces-
sor lock shown above.
Note: The Retention Mechanism processor lock can only lock S.E.C.C. 2

1. The DIP Switch SW1 (1, 2, 3, and 4) 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 CPUClock = 66MHz/100MHz
Core/Bus ratio = 4
then CPU core speed = Host Clock x Core/Busratio
= 66MHzx 4/100MHzx4
= 266MHz/400MHz
SW1 CPU
Note: The CPU Bus Frequency is set at 66MHz or 100MHz by CPU
default.

2.1-3 CPU Speed Setting: SW1
To adjust the speed of the CPU, you must know the specification of your
CPU (always ask the vendor for CPU specification). The mainboard can
auto-detect between 66 or 100MHz CPU Bus Frequency.

2.1-4 Fan Power Connectors: CPUFAN/PSFAN/SYSFAN
These connectors support 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. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.

For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: 1. Always consult vendor for proper CPU cooling fan.
2. CPU FAN supports the FAN control. You can install PC Alert
utility. This will automatically control the CPU FAN Speed according
to the actual CPU temperature.
