CyberResearch®Motherboards MXMA Series

Chapter1 <Introduction>

1.1 <Product Overview>

MXMA is based on a motherboard built with Intel desktop technology and an industrial

form factor. Using the Intel 945G and ICH7R, the board integrates a new Pentium 4
processor 775-pin socket, DDR2 memory slot, Intel Graphic Media Accelerator 950
technology, PCI express interface and Serial ATA II with RAID function for a powerful
desktop system.

Intel LGA775 processor

The Intel Pentium 4 processor now comes with a new form factor: 775-pin PLGA
package, for 533/800/1066MHz front-side-bus, 2MB L2 cache, and for 90nm manufacturing
technology, the PLGA processor without a pin header on the solder side of the board makes for
easier intstallation.

Intel 945G and ICH7R chipset

The Intel 945G integrates DDR2 400/533/667MHz for memory, and Graphic Media
Accelerator (GMA) 950 technology for a new graphic engine. It can provide up to 224MB of
frame buffer when you install it over 256MB of system memory. The ICH7R integrates with up
to 8 USB2.0 interfaces, and serial ATA II interface with RAID functionality.

One Marvell E8053

One Gigabit LAN with Marvell E8053, the MXMA comes with powerful network functionality for
fast and large data transfer; ideal for a NAS system or Server platform.

PCI-Express interface

MXMA integr ates one x16, x4 and x1 PCI-Express interface, it can provide up to 8GB/s of
bandwidth ( AGP 8x can only provide up to 2GB/s).

Multimedia interfaces

MXMA also integrates 7.1 channel HD audio, PCI-Express, PCI and ISA interface, for these

flexible function, system integrator can built more powerful systems for many applications.

3.2 <SATA RAID Configuration>

The board integrates Intel ICH7R with RAID function for Serial ATA II drives, and supports
the configurations below:
RAID 0 (Stripping): Two hard drives operating as one drive for optimized data R/W
performance. Requires two unused drives.
RAID 1 (Mirroring): Copies the data from first drive to second drive for data security, and if
one drive fails, the system can access the applications through the workable drive. This requires
two unused drives, or one used and one un used drive. T he second drive must be the same or
larger size than first one.

RAID 5 (striping with parity)

A RAID 5 array contains three or more hard drives where the data is divided into
manageable blocks called strips. Parity is a mathematical method for recreating data that
was lost from a single drive, which increases fault-tolerance. The data and parity are striped
across all the hard drives in the array. The parity is striped in a rotating sequence to reduce
bottlenecks associated with the parity calculations.

RAID 10 (RAID 0+1)

A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1. The
data is striped across a two-drive array forming the RAID 0 component. Each of the drives
in the RAID 0 array is then mirrored by a RAID 1 component.
Intel Matrix Storage Technology : This technology would allow you to use RAID 0+1 mode
on only two drives (4 drives needed on traditional RAID 0+1). It will create two partitions on
each hard drive to simulate RAID 0 and RAID 1. It also can let you modify the partition size
without re-formatted.

For more information of Intel Matrix Storage Technology, please visit Intel’s website.

If you need to install an operating system on the RAID set, please use the supplied
driver disk when prompted for the RAID drivers during installation.

Chapter 4 <BIOS Setup>

The motherboard uses the Award BIOS for the system configuration. The Award
BIOS in the single board computer is a customized version of the industrial standard
BIOS for IBM PC AT-compatible computers. It supports Intel x86 and compatible CPU
architecture based processors and computers. The BIOS provides critical low-level
support for the system central processing, memory and I/O sub-systems.

The BIOS setup program of the single board computer let the customers modify the
basic configuration setting. The settings are stored in a dedicated battery-backed
memory, NVRAM, retains the information when the power is turned off. If the battery
runs out of the power, then the settings of BIOS will come back to the default setting.

The BIOS section of the manual is subject to change without notice and is provided here
for reference purpose only. The settings and configurations of the BIOS are current at
the time of print, and therefore they may not be exactly the same as that displayed on
your screen.

To activate CMOS Setup program, press ІDELЇ key immediately after you turn on
the system. The following message “Press DEL to enter SETUP” should appear in the
lower left hand corner of your screen. When you enter the CMOS Setup Utility, the Main
Menu will be displayed as Figure 4-1. You can use arrow keys to select your function,
press ІEnterЇ key to accept the selection and enter the sub-menu.

Product Service

Diagnosis and Debug

CyberResearch, Inc. maintains technical support lines staffed by experienced
Applications Engineers and Technicians. There is no charge to call and we will
return your call promptly if it is received while our lines are busy. Most problems
encountered with data acquisition products can be solved over the phone. Signal
connections and programming are the two most common sources of difficulty.
CyberResearch support personnel can help you solve these problems, especially
if you are prepared for the call.

To ensure your call’s overall success and expediency:

1) Have the phone close to the PC so you can conveniently and quickly take
action that the Applications Engineer might suggest.

2) Be prepared to open your PC, remove boards, report back-switch or
jumper settings, and possibly change settings before reinstalling the
modules.

3) Have a volt meter handy to take measurements of the signals you are
trying to measure as well as the signals on the board, module, or power
supply.

4) Isolate problem areas that are not working as you expected.

5) Have the source code to the program you are having trouble with available
so that preceding and prerequisite modes can be referenced and
discussed.

6) Have the manual at hand. Also have the product’s utility disks and any
other relevant disks nearby so programs and version numbers can be
checked.

Preparation will facilitate the diagnosis procedure, save you time, and avoid
repeated calls. Here are a few preliminary actions you can take before you call
which may solve some of the more common problems:

1) Check the PC-bus power and any power supply signals.

2) Check the voltage level of the signal between SIGNAL HIGH and SIGNAL
LOW, or SIGNAL+ and SIGNAL– . It CANNOT exceed the full scale range
of the board.

3) Check the other boards in your PC or modules on the network for address

Returns and RMAs

If a CyberResearch product has been diagnosed as being non-functional, is visibly
damaged, or must be returned for any other reason, please call for an assigned
RMA number. The RMA number is a key piece of information that lets us track and
process returned merchandise with the fastest possible turnaround time.

PLEASE CALL FOR AN RMA NUMBER!

Packages returned without an RMA number will be refused!

In most cases, a returned package will be refused at the receiving dock if its
contents are not known. The RMA number allows us to reference the history of
returned products and determine if they are meeting your application’s requirements.
When you call customer service for your RMA number, you will be asked to provide
information about the product you are returning, your address, and a contact person
at your organization.

Please make sure that the RMA number is prominently

displayed on the outside of the box.
