1.1 B

EFORE YOU START

Thank you for choosing our product. Before you start installing the
mainboard, please make sure you follow the instructions below:

 Prepare a dry and stable working environment with

sufficient lighting.

 Always disconnect the system from power outlet

before operation.

 Before you take the mainboard out from anti-static

bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static charge.

 Avoid touching the components on mainboard or the

rear side of the board unless necessary. Hold the board
on the edge, do not try to bend or flex the board.

 Do not leave any unfastened small parts inside the

case after installation. Loose parts will cause short
circuits which may damage the equipment.

 Keep the system from dangerous area, such as heat

source, humid air, and water.

ATA Device Connector

The mainboard has a 32-bit Enhanced PCI IDE Controller that provides PIO
Mode 0~4, Bus Master, and Ultra DMA 33/66/100/133 functionality. It has one
IDE connector.

The IDE connector can connect a master and a slave drive, so you can connect
up to two ATA devices.

Be aware of that the CF socket on the back panel uses IDE Master as
default channel. If the CF socket is inserted with CF card, the ATA
connector would allow only one device and the device should be set to
IDE Slave.

Mini PCI Slot

Mini-PCI socket for TYPE III B (32-bit, 33MHz), Power supply: +3.3V, +12V.

Mini PCI is a standard for a computer bus for attaching peripheral devices to a
computer mainboard and is an adaptation of the Peripheral Component
Interconnect (PCI) bus.

Many Mini PCI devices are available today: WiFi, modems, sound cards,
cryptographic accelerators, SCSI, IDE/ATA and SATA controllers.

CX70M-PE

Reset Configuration Data

The system BIOS supports the PnP feature which requires the system to
record which resources are assigned and protects resources from
conflict.

Every peripheral device has a node, which is called ESCD. This node
records which resources are assigned to it. The system needs to record
and update ESCD to the memory locations. These locations are
reserved in the system BIOS. If the Disabled (default) option is chosen,
the system‘s ESCD will update only when the new configuration varies
from the last one. If the Enabled option is chosen, the system is forced
to update ESCDs and then is automatically set to the “Disabled” mode.

The above settings will be shown on the screen only if “Manual” is
chosen for the resources controlled by function.

Legacy is the term, which signifies that a resource is assigned to the ISA
Bus and provides non-PnP ISA add-on cards. PCI / ISA PnP signify that
a resource is assigned to the PCI Bus or provides for ISA PnP add-on
cards and peripherals.

The Choices: Disabled (Default) / Enabled

Resources Controlled By

By Choosing “Auto(ESCD)” (default), the system BIOS will detect the
system resources and automatically assign the relative IRQ and DMA
channel for each peripheral. By Choosing “Manual”, the user will need to
assign IRQ & DMA for add-on cards. Be sure that there are no IRQ/DMA
and I/O port conflicts.

CHAPTER 4: RAID FUNCTIONS

4.1 O

Supports Windows XP Home/Professional Edition, and Windows 2000 Professional.

PERATING SYSTEM

4.2 RAID ARRAYS

RAID supports the following types of RAID arrays:

RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for

many applications.

RAID 1: RAID 1 defines techniques for mirroring data.

4.3 HOW RAID WORKS

RAID 0:

The controller “stripes” data across multiple drives in a RAID 0 array system. It breaks
up a large f i le int o sm alle r blo cks and per for ms d isk r ead s and w rite s across multip le
drives in parallel. The size of each block is determined by the stripe size parameter,
which you set during the creation of the RAID set based on the system environment. This
technique reduces overall disk access time and offers high bandwidth.

Features and Benefits

 Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the

platform.

 Uses: Intended for non-critical data requiring high data throughput, or any

environment that does not require fault tolerance.

 Benefits: provides increased data throughput, especially for large files. No

capacity loss penalty for parity.

 Drawbacks: Does not deliver any fault tolerance. If any drive in the array

fails, all data is lost.

 Fault Tolerance: No.

56

Block 1
Block 3
Block 5

Block 2
Blo ck 4
Blo ck 6

CX70M-PE

RAID 1:

Every read and write is actually carried out in parallel across 2 disk drives in a RAID 1
array system. The mirrored (backup) copy of the data can reside on the same disk or on a
second redundant drive in the array. RAID 1 provides a hot-standby copy of data if the
active volume or drive is corrupted or becomes unavailable because of a hardware failure.

RAID techniques can be applied for high-availability solutions, or as a form of automatic
backup that eliminates tedious manual backups to more expensive and less reliable
media.

Features and Benefits

 Drives: Minimum 2, and maximum is 2.
 Uses: RAID 1 is ideal for small databases or any other application that

requires fault tolerance and minimal capacity.

 Benefits: Provides 100% data redundancy. Should one drive fail, the

controller switches to the other drive.

 Drawbacks: Requires 2 drives for the storage space of one drive.

Performance is impaired during drive rebuilds.

 Fault Tolerance: Yes .

5.3 EXTRA INFORMATION

CPU Overheated

If the system shutdown automatically after power on system for
seconds, that means the CPU protection function has been activated.

When the CPU is over heated, the mainboard will shutdown
automatically to avoid a damage of the CPU, and the system may not
power on again.

In this case, please double check:

1. The CPU cooler surface is placed evenly with the CPU surface.

2. The CPU fan is rotated normally.

3. The CPU fan speed is fulfilling with the CPU speed.

After confirmed, please follow steps below to relief the CPU protection
function.

1. Remove the power cord from power supply for seconds.

2. Wait for seconds.

3. Plug in the power cord and boot up the system.

Or you can:

1. Clear the CMOS data.
(See “Close CMOS Header: JBAT1” section)

2. Wait for seconds.

3. Power on the system again.
