Central Processing Unit: CPU

The mainboard supports Single/Dual Intel ® Xeon™ processor(s). The mainboard uses two CPU sockets called Socket 604 for easy CPU installation.

You can install SINGLE or DUAL CPUs on the board to meet your own needs. Keep the following points in mind before installing CPU(s):

1. If SINGLE CPU is intended, always install the CPU on the CPU1 socket.

Recommended inlet air direction

CPU1

2. To install DUAL CPUs on the board, you must use the same type

of CPUs running at the same FSB frequency.

When you are installing the CPU, make sure the CPU has a Heat Sink

and a cooling fan attached on the top to prevent overheating. If you do not find the Heat Sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.


Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect the CPU from overheating.

The system temperature needs to remain under 45°C.

We highly recommend that the direction of inlet air should follow the direction indicated above for better cooling effect.

2-3


CPU Installation Procedures for Socket 604

1. Please turn off the power and unplug the power cord before installing the CPU.

Open Lever

2. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90degree angle.

3. Look for the cut edge. The cut edge should point towards the lever pivot. The CPU can only fit in the correct orientation.

Dot / Cut Edge

Dot / Cut Edge 4. I f t h e C P U i s c o r r e c t l y installed, the pins should be completely embedded into the socket and can not be seen.

Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.

5. Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

Memory

The mainboard provides 6 slots for 184-pin DDR SDRAM DIMM

(Double In-Line Memory Module) modules and supports up to 12GB memory size. You can install PC2100/DDR266 or PC1600/DDR200 modules on the

DDR DIMM slots (DIMM 1~6).

DIMM Module Combination

The mainboard supports dual channel (144-bit wide) DDR266/200 memory interface. Each channel supports 3 DIMM slots.

Each DIMM slot supports up to a maximum size of 2GB. Users can install either single- or double-sided modules depending on their needs, but memory modules must be installed on the board IN PAIRS.

Make sure that you install memory modules of the same type and

density on DDR DIMMs “in pairs” -- {DIMM1 & DIMM2},

{DIMM3 & DIMM4}, {DIMM5 & DIMM6}.

Installing DDR Modules

1.

The DDR DIMM has only one notch on the center of module. The module will only fit in the right orientation.

2.

Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the socket.


You can barely see the golden finger if the module is properly

inserted in the socket.

3. The plastic clip at each side of the DIMM slot will automatically close.

Power Supply

The mainboard supports SSI power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused.

SSI 24-Pin Power Connector: POWERJ1

This connector allows you to connect an SSI power supply. To connect the SSI power supply, make sure the plug of the power supply is inserted in the proper orientation and the pins are aligned. Then push down the power supply firmly into the connector.

Five-Fan Module Power Connector: FAN

A module consisting of five 40mm, multi-speed fans provides the primary airflow for the system. A 12-wire cable/connector provides the fan module with power and tach lines, allowing each fan to be monitored independently by server management software. The power cable is connected to a 12pin header located on the mainboard.

The fan module is a single component. The individual fans that make up the module are not swappable or individually replaceable. Should a fan fail, the entire module will need to be replaced. A tab on the side of the fan module makes replacement of the module tool-less and very simple. As the fan module is not hot swappable, the server must be turned off before the fan module can be replaced.

Slots

The motherboard provides two 64-bit Master PCI-X bus slots and one

Mini PCI slot.

64-bit PCI-X Slot (ZCR)

64-bit PCI-X Slot

Mini PCI Slot

PCI (Peripheral Component Interconnect) Slots

The PCI slots allow you to insert the expansion cards to meet your needs.

When adding or removing expansion cards, make sure that you unplug the power supply first. Meanwhile, read the documentation for the expansion card to make any necessary hardware or software settings for the expansion card, such as jumpers, switches or BIOS configuration. The mainboard provides two Master 64-bit PCI (also called PCI-X) bus slots and one Mini PCI slot.

64-bit PCI-X bus: The bus has 64 data lines and runs at 100MHz.

With twice data lines and much faster PCI clock, the 64-bit PCI bus increases the throughput and overall system performance. The 64-bit

PCIX1 Slot in GREEN color is the only PCI slot where the Zero Chan-

nel RAID (ZCR) card can be installed.

2-27


Mini PCI bus

This bus is used to connect the optional MS-9518 SCSI card.

MS-9518 SCSI card

Installing the card:

1. Locate the Mini PCI slot on the mainboard.

Mini PCI slot

2. Place the card over the Mini PCI slot and gently insert both ends of the card slantways (at an angle of 45 degrees) into the slot until the golden finger of the card gets fully inserted into the slot.

2-28


You can barely see the golden finger if the card is properly

inserted in the socket.


3. Locate the supporters on the mainboard (one on the right end and the other on the left end).

4. Align the two fixing holes on the card with the supporters and press the card carefully down until the fixing holes get locked by the supporters.

supporters

Supporters lock into the fixing holes of the card.

5. Push the retaining clips (on two ends of the slot) inwards until they lock onto the notches in the ends of the card. The card should securely fit into the slot.

2-29


Removing the card:

1. Gently push the retaining clips outwards. Hold the card lightly but firmly. Use long nose pliers to clip one of the supporters and press it downwards until it withdraws from the fixing hole.

2. Clip the other supporter and press it downwards until it withdraws from the fixing hole.

3. The card will automatically bound upwards after being released from the supporters.

4. Remove the card from the Mini PCI slot.

Sync Transfer Rate (MB/Sec)

The field allows you to specify the maximum synchronous data transfer rate depending on the type of each SCSI device. Select ASYN to enable asynchronous negotiation for some older SCSI devices.

Packetized

When enabled, this option is supported by the device drivers. However, this option is not supported by the BIOS.

QAS

When enabled, this option is supported by the device drivers. However, this option is not supported by the BIOS.

Initiate Wide Negotiation

When set to Yes, the field allows wide SCSI hard drives to use 16-bit (2 bytes) transfers.

Enable Disconnection

This field tells the SCSI controller whether or not to allow the specified


SCSI device to disconnect during an I/O transfer operation. The disconnection ability frees the SCSI bus to allow other I/O processes and thus optimizes the SCSI bus performance. Setting options: Yes, No.

Send Start Unit Command

When set to Yes, the SCSI controller sends the Start Unit command to the specified SCSI device during bootup. The interface powers up the SCSI device on-at-a-time during bootup, reducing the load on the computer’s power supply. Setting options: Yes, No.

BIOS Multiple LUN Support

Select Yes when any SCSI device has multiple logical units. Setting options: Yes, No.

Include in BIOS Scan

Selecting Yes allows the SCSI controller to control the SCSI device with its SCSI ID. When set to No, the SCSI controller does not control the specified SCSI device by not scanning for the SCSI ID during bootup, but the boot time will be decreased. Setting options: Yes, No.

Extended Int 13 Translation for DOS Drives > 1 GByte

The field allows SCSI hard disk drives greater than 1 GB to use a translation scheme of 255 heads, 63 sectors per track. Setting options: Enabled,

Disabled.

POST Display Mode

The field determines how much information about your SCSI controller and devices appear on the screen during bootup. For the most complete information, choose Diagnostic. For a faster boot, select Silent. Setting options: Verbose, Silent, Diagnostic.

SCSI Controller Int 13 Support

The field allows you to enable or disable the support for Int 13h. The software interrupt “Int 13h” is the interface through which the operating system or application is able to pass commands to hard disk drives, such as reading, writing and formatting. Setting options: Enabled, Disabled:

NOT scan, Disabled: scan bus.

Domain Validation

When enabled, these options are available if they are implemented in the device drivers. However, this option is not supported by the BIOS.

Support Removable Disks Under Int13 as Fixed Disks

When Boot Only is selected, only the removable media drive designated as the boot device will be treated as a hard disk drive. When All Disks is selected, all removable media drives supported by the BIOS are treated as hard disk drives. If selecting Disabled, no removable media drive is treated as a hard disk drive and the removable media drives must be controlled by the OS drivers.

BIOS Support for Bootable CD-ROM

When enabled, the SCSI controller BIOS supports bootable CD-ROM under the El Torito specification. If booting from a hard disk or other

SCSI BIOS Setup device, make sure no bootable CD-ROM is inserted or disable this option.

A: Please refer to the following suggestions: 1. Try the BIOS boot recovery feature as described in http://www.msi.com.tw/support/bios/boot.htm 2. Try to clear the CMOS If problem still persists, ask your reseller for new BIOS chip or contact one of MSI office near your place for new BIOS chip http:// www.msi.com.tw/contact/main.htm

Q: Should I update my BIOS, once a new BIOS is released?

A: A new BIOS is usually released due to the following reasons:

1. New function is supported

T-2


2. New BIOS source code

3. Bugs are found

4. Customer-specific request

When we release a new BIOS, there's usually a release note attached which lists the reason for the release. Refer to this release note and decide for yourself if upgrading to the new BIOS will be worth it. A word of advice, though, do not upgrade to the new BIOS, unless you really have to.

Q: How do I update the BIOS?

A: Please refer to http://www.msi.com.tw/support/bios/note.htm for details.

Q: How do I identify the BIOS version?

A: Upon boot-up, the 1st line appearing after the memory count is the BIOS version. It is usually in the format:

1. For older model number:

AG76 091096 where:

1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R) P = PHOENIX

(R).

2nd digit refers to the internal chipset code.

3rd digit refers to the processor class as 5 = 486, 7 = 586, 8 = 686.

4th digit is incremental.

091096 refers to the date this BIOS is released.

2. For newer model number:

W5139MS V1.0 091096 where:

1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R) P = PHOENIX

(R).

2nd - 5th digit refers to the model number.

6th - 7th digit refers to the customer as MS = all standard customers.

V1.0 refers to the BIOS version.

091096 refers to the date this BIOS is released.

T-3


Q: After I flashed the BIOS and rebooted the system, the screen went blank.

A: For AMI BIOS

Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM

Insert this floppy disk in the floppy drive. Turn On the system and press and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file and recover the BIOS from the A drive.

When 4 beeps are heard you may remove the floppy disk and restart the computer.

For Award BIOS

Make a bootable floopy disk

Copy the Award flash utility & BIOS file to the said floppy disk

Create an autoexec.bat with "awdfl535 biosfilename" in the content e.g.

awdfl535 a619mj21.bin

Boot up system with the said floppy (it will take less than 2 minutes before screen comes out)

Re-flash the BIOS & reboot.

ACPI (Advanced Configuration & Power Interface)

This power management specification enables the OS (operating system) to control the amount of power given to each device attached to the computer. Windows 98/98SE,

Windows 2000 and Windows ME can fully support ACPI to allow users managing the system power flexibly.

AGP (Accelerated Graphics Port)

A new, high-speed graphics interface that based on PCI construction and designed especially for the throughput demands of 3-D graphics. AGP provides a direct channel

(32-bit wide bus) between the display controller and main memory for high graphics quality and performance.

Bluetooth

Bluetooth refers to a worldwide standard for the wireless exchange of data between two devices. Bluetooth requires that a low-cost transceiver chip be included in each device.

The tranceiver transmits and receives in a previously unused frequency band of 2.45

GHz that is available globally (with some variation of bandwidth in different countries).

In addition to data, up to three voice channels are available. Each device has a unique 48bit address from the IEEE 802 standard. Connections can be point-to-point or multipoint. The maximum range is 10 meters. Data can be exchanged at a rate of 1 megabit per second (up to 2 Mbps in the second generation of the technology).

BIOS (Basic Input/Output System)

On PCs, an essential software that contains all the control code of input/output interface (such as keyboard, disk drives, etc.). It executes hardware test on booting the system, starts the OS, and provides an interface between the OS and the components.

The BIOS is stored in a ROM chip.

Bus

A set of hardware lines within the computer system, through which the data is transferred among different components. In a PC, the term bus usually refers to a local bus that connects the internal components to the CPU and main memory.

Cache

A special memory subsystem that is used to speed up the data transfer. It stores the

G-1

MS-9125 SSI Mainboard contents of frequently accessed RAM locations and the addresses where these data items are stored.

Chipset

A collection of integrated chips designed to perform one or more related functions. For example, a modem chipset contains all the primary circuits for transmitting and receiving data; a PC chipset provides the electronic interfaces between all subsystems.

Clock Cycle

Clock cycle (or tick) is the smallest unit of time recognized by a device. For personal computers, clock cycles generally refer to the main system clock, which runs at 66

MHz. This means that there are 66 million clock cycles per second. Since modern

CPUs run much faster (up to 533 MHz), the CPU can execute several instructions in a single clock tick.

CMOS (Complementary Metal-Oxide Semiconductor)

CMOS is a widely used type of semiconductor, which features high speed and low power consumption. PCs usually contain a small amount of battery-powered CMOS memory to retain the date, time, and system setup parameters.

DRAM (Dynamic RAM)

A most common type of computer memory. It usually uses one transistor and a capacitor to represent a bit. As the development of technology, the memory type and specification used in computer becomes variety, such as SDRAM, DDR SDRAM, and

RDRAM. For further instruction, please see the table below:

ECC Memory (Error Correcting Code Memory)

A type of memory that contains special circuitry for testing the accuracy of data and correcting the errors on the fly.

EEPROM

Acronym for Electrically Erasable Programmable Read-Only Memory. An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off. Also like other types of ROM, EEPROM is not as fast as RAM. EEPROM is similar to flash memory (sometimes called flash EEPROM). The principal difference is that EEPROM requires data to be written or erased one byte at a time whereas flash memory allows data to be written or erased in blocks. This makes flash memory faster.

EIDE

Short for Enhanced IDE, a newer version of the IDE mass storage device interface standard developed by Western Digital Corporation. It supports data rates of between

4 and 16.6 MBps, about three to four times faster than the old IDE standard. In addition, it can support mass storage devices of up to 8.4 gigabytes, whereas the old standard was limited to 528 MB. Because of its lower cost, enhanced EIDE has replaced SCSI in many areas. There are four EIDE modes defined. The most common is Mode 4, which supports transfer rates of 16.6 MBps. There is also a new mode, called ATA-3 or Ultra ATA, that supports transfer rates of 33 MBps.

EISA (Extended Industry Standard Architecture)

EISA is a standard bus (computer interconnection) architecture that extends the ISA standard to a 32-bit interface. It was developed in part as an open alternative to the proprietary Micro Channel Architecture (MCA) that IBM introduced in its PS/2 computers. EISA data transfer can reach a peak of 33 megabytes per second.

ESCD (Extended System Configuration Data)

It is a format for storing information about Plug-and-Play (PnP) devices in the BIOS.

Windows and the BIOS access the ESCD area each time you re-boot your computer

External Cache

Short for Level 2 cache, cache memory that is external to the microprocessor. In general, L2 cache memory, also called the secondary cache, resides on a separate chip from the microprocessor chip. Although, more and more microprocessors are including

L2 caches into their architectures.

G-3


IDE (Integrated Drive Electronics)

A type of disk-drive interface widely used to connect hard disks, CD-ROMs and tape drives to a PC, in which the controller electronics is integrated into the drive itself, eliminating the need for a separate adapter card. The IDE interface is known as the

ATA (AT Attachment) specification.

IEEE 1394

A new, high speed external bus standard, also known as FireWire or iLink, which supports data transfer rates of up to 400 Mbps for connecting up to 63 external devices.

Internal Cache

Short for Level 1 cache, a memory cache built into the microprocessor. The L1 cache is also called the primary cache.

IrDA (Infrared Data Association)

A group of device vendors, including computer, component and telecommunications, who have developed a standard for transmitting data via infrared light waves. This enables you to transfer data from one device to another without any cables.

IRQ (Interrupt Request Line)

IRQs are hardware lines over which devices can send interrupt signals to the microprocessor. When you add a new device to a PC, you sometimes need to set its

IRQ number by setting a DIP switch. This specifies which interrupt line the device may use. IRQ conflicts used to be a common problem when adding expansion boards, but the Plug-and-Play specification has removed this headache in most cases.

ISA (Industry Standard Architecture)

ISA is a standard bus (computer interconnection) architecture that is associated with the IBM AT motherboard. It allows 16 bits at a time to flow between the motherboard circuitry and an expansion slot card and its associated device(s). Also see EISA and

MCA.

LAN (Local Area Network)

A computer network that covers a relatively smaller area, such as in a building or an enterprise. It is made up of servers, workstations, shared resources, a network operating system and a communications link. These individual PCs and devices on a LAN are known as “nodes”, and are connected by cables to access data and devices anywhere on the LAN, so that many users can share expensive devices and data.

Glossary

LBA (Logical Block Addressing)

Logical block addressing is a technique that allows a computer to address a hard disk larger than 528 megabytes. A logical block address is a 28-bit value that maps to a specific cylinder-head-sector address on the disk. 28 bits allows sufficient variation to specify addresses on a hard disk up to 8.4 gigabytes in data storage capacity. Logical block addressing is one of the defining features of Enhanced IDE (EIDE), a hard disk interface to the computer bus or data paths.

LED (Light Emitting Diode)

A semiconductor device that converts electrical energy into light. Since it lights up

(usually red) when electricity is passed through it, it is usually used for the activity lights on computer’s component, such as disk drivers.

LPT (Line Printer Terminal)

Logical device name for a line printer; a name reserved by the MS-DOS for up to three parallel printer ports: LPT1, LPT2, and LPT3. It is frequently used by the OS to identify a printer.

Overclocking

Overclocking is resetting your computer so that the microprocessor runs faster than the manufacturer-specified speed (for example, setting an Intel 166 MHz (megahertz) microprocessor to run at 200 Mhz).

PCI (Peripheral Component Interconnect)

A local bus standard developed by Intel that first appeared on PCs in late 1993. PCI provides “plug and play” capability and allows IRQs to be shared. The PCI controller can exchange data with the system's CPU either 32 bits or 64 bits at a time.

PnP (Plug and Play)

A set of specifications that allows a PC to configure itself automatically to work with peripherals. The user can "plug" in a peripheral device and "play" it without configuring the system manually. To implement this useful feature, both the BIOS that supports PnP and a PnP expansion card are required.

POST (Power On Self Test)

During booting up your system, the BIOS executes a series of diagnostic tests, include checking the RAM, the keyboard, the disk drives, etc., to see if they are properly connected and operating.

G-5


PS/2 Port

A type of port developed by IBM for connecting a mouse or keyboard to a PC. The

PS/2 port supports a mini DIN plug containing just 6 pins. Most modern PCs equipped with PS/2 ports so that the special port can be used by another device, such as a modem.

RAID

RAID (Redundant Array of Independent Disks; originally Redundant Array of Inexpensive Disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. By placing data on multiple disks, I/O operations can overlap in a balanced way, improving performance. Since multiple disks increases the mean time between failure (MTBF), storing data redundantly also increases fault-tolerance.

SCSI

Acronym for Small Computer System Interface. Pronounced "scuzzy," SCSI is a parallel interface standard used by Apple Macintosh computers, PCs, and many UNIX systems for attaching peripheral devices to computers. SCSI interfaces provide for faster data transmission rates (up to 80 megabytes per second) than standard serial and parallel ports. In addition, you can attach many devices to a single SCSI port, so that

SCSI is really an I/O bus rather than simply an interface.

USB (Universal Serial Bus)

A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick, etc. USB provides a maximum bandwidth of 12 Mbit/sec (Mbps) for connecting up to

127 peripheral devices to PC. USB features hot swap capability and multiple data streams, allows external devices to be plugged in and unplugged without turning the system off.

Virus

A program or a piece of code that infects computer files by inserting in those files copies of itself. The virus code is buried within an existing program, and is activated when that program is executed. All the viruses are man-made, and often have damaging side effects.

WLAN

Acronym for wireless local-area network. Also referred to as LAWN. A type of localarea network that uses high-frequency radio waves rather than wires to communicate between nodes.
