Introduction 
The Pro266 Master (MS-6366) ATX mainboard is a high-performance
computer mainboard based on Apollo Pro266 chipset and designed for the
ntel® CeleronTM or Pentium !!! (FC-PGA) processor for inexpensive busi-
ness/personal desktop markets.
The Apollo Pro266 chipset consists of the VT8633 V-Link DDR Host
system controller and the VT8233 highly integrated V-Link Client PC /LPC
controller. The VT8633 provides superior performance between the CPU,
DRAM, AGP bus and V-Link interface with pipelined, burst, and concurrent
operation and supports eight banks of SDR/DDR SDRAMs up to 4 GB and
full AGP v2.0 capability including 2x and 4x mode transfers, SBA (SideBand
Addressing), Flush/Fence commands, and pipelined grants.
The V A® VT8233 South Bridge enhances the functionality of the
standard SA peripherals and supports delayed transactions and remote
power management so that slower SA peripherals do not block the traffic of
the PC bus. n addition, the VT8233 includes eight levels (doublewords) of
line buffers from the PC bus to the SA bus to further enhance overall
system performance.

PC Alert III
The PC AlertTM is a utility you can find in the CD-ROM. The utility
is just like your PC doctor that can detect the following PC hardware status
during real time operation:
* monitor CPU & system temperature
* monitor fan speed
* monitor system voltage
* monitor chassis intrusion
f one of the items above is abnormal, the program main screen will be immedi-
ately shown on the screen, with the abnormal item highlighted in red. This will
continue to be shown,until user disables warning.

The D-LED uses graphic signal display to help
users understand their system. Four LEDs embedded in
the mainboard provide up to 16 combinations of signals to
debug the system. The 4 LEDs can debug all problems that
fail the system, such as VGA, RAM or other failures. This
special feature is very useful for the overclocking users.
These users can use the feature to detect if there are any
problems or failures.

Chapter 2. Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the compo-
nents and follow the installation procedures. For some components, if you
install in the wrong orientation, the components will not work properly.
Besides, use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

The mainboard supports Intel® eleronTM and oppermineTM
processor. The mainboard uses a PU socket called Socket 370 for easy
PU installation. Make sure the PU has a Heat Sink and a cooling fan
attached on top to prevent overheating. If you do not find the Heat Sink
and cooling fan, contact your dealer or purchase and install them before
turning on the computer.
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Align the pins on the PU
with the pin positions on the
socket carefully and place
the PU on it. The mark of
the PU will be next to the
lever end.
3. Hold the PU firmly, and
then press the lever down to
complete the installation.
Overheating will seriously damage the CPU
and system, always make sure the cooling fan can work
properly to protect the CPU from overheating.

CPU Core Speed Derivation Procedure
The mainboard can automatically set the PU Host Bus Frequency lock.
If PU lock = 100MHz
ore/Bus ratio = 7
then PU core speed = Host lock x ore/Bus ratio
= 100MHz x 7
= 700MHz

The mainboard provides 3 sockets for 184-pin, 2.5V DDR DIMM with 6
memory banks and 2 sockets for 168-pin, 3.3V SDR DIMM with 4 memory
banks. To operate properly, at least one DIMM module must be installed.

You can install single sided or double sided 168-pin DIMMs into SDR
DIMM slots according to your needs.
SDR Module Installation Procedures
Sing e Sided DIMM
Doub e Sided DIMM
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 SDR DIMM
slot. Then push it in.
3. The plastic clips at sides of the DIMM slot will automatically
close.

DDR Module Installation Procedures
You can also install single sided or double sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breasks are different. The module will only
fit in the right orientation.
1. Insert the DIMM module vertically into the DDR DIMM slot. Make sure the
notch is on the right orientation.
2. The plastic clips at sides of the DIMM slot will automatically close.
