MSI MICRO ATX ZX14 User manual

CHAPTER 1 INTRODUCTION
1-1
The MICRO ATX ZX14 mainboard is a high-performance personal computer
mainboard based on the Intel®Pentium®II/Pentium®III/CeleronTM processor.
This mainboard combines leading edge 3Dfx Voodoo 3 technology in
graphics and Creative®ES1373 PCI technology in audio. The Intel®Pentium®
II/III/CeleronTM processor supports MMXTM (Multimedia Extension)
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
The mainboard operates with Intel®Pentium®II/III/CeleronTM processor.
The mainboard uses a CPU Slot called Slot 1 for easy CPU installation and a
jumper switch (SW1) to set the proper speed for the CPU. The CPU should
always have a Heat Sink and a cooling fan attached to prevent overheating.

2.1-1 CPU Installation Procedures
A. OEM Pentium®II/III Processor Installation Procedures
Different kinds of Pentium®II/III processor that is currently used: the OEM
version, the Boxed version, and CeleronTM. OEM Pentium®II/III Processor
has no Heat Sink, Fan and Heat Sink Support, the Boxed Pentium®II/III
Processor is provided with Heat Sink w/ fan and Heat Sink Support, while
the CeleronTM processor is a plain processor card without cover or heatsink.
Required Things:
Pentium®II/III processor- Processor.
*RetentionMechanism(RM)- Plastic Guide that holds the S.E.C.Catridge
in the Slot 1 connector.
*RetentionMechanism AttachMount(RMAM)-Bolt/Bridge assemblies
inserted up through the bottom of the
motherboard. RM secures to RMAM ( 2
RMAM required per RM ).

Step 4: Install the Heat Sink with Fan to the Processor.
Push down the metal clips, so that they are in line with the back of
the Heat Sink. Be careful, so as not detach the metal clips from the
HeatSink.
In case the metal clips are detached from the Heat Sink, re-attach
them. Look for the arrow on the metal clip. This arrow should be
pointing down and aligned with the Heat Sink Support Base Holder.
Attach the Heat Sink to the processor.
- Look at the back of the Heat Sink and take note of the 2 secure
posts. Insert these 2 Secure posts to the 2 secure holes on the
back of the processor.
- Align the ears of the metal clips with the clip holders on the back of
the processor. Use a screw driver to push the metal clips onto the
clip holders. Check for a perfect fit.

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/Bus ratio
= 66MHzx 4/100MHzx4
= 266MHz/400MHz

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
This connector 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.
