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®
ES1373PCItechnologyinaudio,andIntel®82558 10/100M Ethernet for
LAN. The Intel®CeleronTM processor supports MMXTM (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 CPUClock =66MHz
Core/Bus ratio = 5.5
then CPU core speed = Host Clock x Core/Bus ratio
=66MHz x5.5
=333MHz

2.1-3 Overclocking Jumper: JP3
This Jumper is only used for overclocking. Changing the CPU system Bus
Speed will alter the AGP clock speed.
AGP clock = CPU clock
AGP clock = CPU clock x 2/3
JP3 Formula
NOTE: This feature only works with 100MHz FSB.
We provide CPU Bus Frequency setting for over
100MHz. But we do not guarantee that the
Motherboard or other components will work properly
after overclocking.
