with the addition of 133 MHz capability for both the CPU and SDRAM
interfaces. Apollo Pro133A may be used to implement both desktop and
notebook personal computer systems from 66MHz to 133MHz based on
Socket-370 (Intel Celeron processors). The primary features of the Apollo
Pro133A-NorthBridgeare:Slot-1orSocket-370CPU(FrontSideBus)
Interface(66/100/133MHz),DRAM Memory Interface (66/100 / 133MHz),
AGP Bus Interface (66MHz), PCIBusInterface (33MHz), Mobile Power
Management.
TheVT82C686A PSIPC (PCI Super-I/O Integrated PeripheralController)is a
high integration, high performance, power-efficient, and high compatibility
device that supports Intel and non-Intel based processor to PCI bus bridge
functionality to make a complete Microsoft PC99-compliant PCI/ISA system.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel®CeleronTM/Coppermine processor. The
mainboard uses a CPU socket called Socket 370 for easy CPU installation.
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. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.

The BIOS can be used to set the CPU Host Bus Frequency Clock.
If CPUClock = 66MHz
Core/Bus ratio = 3.5
then CPU core speed = Host Clockx Core/Bus ratio
= 66MHzx3.5
= 233MHz

2.1-3 Fan Power Connectors: CPUFAN/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.

2.2 Clear CMOS Jumper: JBAT1
A battery must be used to retain the mainboard configuration in CMOS
RAM. Short 1-2 pins of JBAT1 to store the CMOS data.

Note: You can clear CMOS by shorting 2-3 pin, while the system is off.
Then, return to 1-2 pin position. Avoid clearing the CMOS while
the system is on, it will damage the mainboard. Always unplug
the power cord from the wall socket.

Themainboard supports a maximum memory sizeof1.5GB (256-bit technol-
ogy) SDRAM: It provides three 168-pin unbufferedDIMMs (Double In-
Line Memory Module) sockets. It supports 8 MB to 512 Mbytes DIMM
memorymodule.

A. HowtoinstallaDIMMModule
1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.
