The MSI LPX ZX4 mainboard is a high-performance all-in-one computer mainboard based on the Intel® CeleronTM processor. This mainboard combines leading edge SiS 6326 AGP technology in graphics, Creative

®

ES1373 PCI technology in audio, and Intel® 82558 10/100M Ethernet for LAN. The Intel® CeleronTM processor supports MMX

TM

(Multimedia

Extension) technology .

The mainboard uses the highly integrated Intel® 82443ZX AGPset 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 of 33MB/s.

The mainboard also supports the System Hardware Monitor Controller as an optional function. Its functions include: CPU 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® CeleronTM processor. The mainboard uses Socket 370 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.

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.

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 CPU Clock = 66MHz

Core/Bus ratio = 5.5

then CPU core speed = Host Clock x Core/Bus ratio

= 66MHz x 5.5 = 333 MHz

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.
