Supported Processors
This section describes the processors supported by the DX400-SN motherboard and how to install them.
The DX400-SN Motherboard only supports Intel Pentium Xeon processors with a Front
Side bus speed of 400 MHz . If two processors are installed, both processors must run the
same core frequency speed. Installing processors of different core frequencies speed may
damage the motherboard and processors.
The processor is packaged in a Organic Land Grid Array (OLGA). The Pentium Xeon Processors implement
integrated L2caches. The Pentium Xeon processor increases Performance for server and workstation
applications by adding either 512KB or 1MB of integrated L3 cache, which is also 8-way set associative.
The System Bus uses Source-Synchronous Transfer (SST) of address and data to improve performance and
enables data transfers at a frequency of 400MHz.This allows the processors to have 3.2GB/sec data transfer
rate .The control signals and bus phases are based on 100MHz system clock. This enhanced bus protocol
and internal architecture increases performance beyond previous levels.
The Processor Information ROM is a 128 byte read –only device that incorporates Intel processor specific
data .The OEM EEPROM, also known as the Scratchpad EEPROM, is a 128-byte read/write EEPROM in
which an OEM may program system specific data. The Thermal Sensor monitors the temperature of the
processor die.
Installing the Processors and Retention Mechanism
Single processor:
Install the processor in the socket marked ‘CPU0’
For Dualprocessors
the following values must be identical for both processors:
·Host bus speed
·Processor core frequency
·Cache size
·Cache type (either discrete or advanced transfer)
·Operating voltages

3.System Memory
The Intel 82860 Memory Controller Hub (MCH) integrates dual Rambus* channels, providing a
processor to memory bandwidth up to 3.2 GB/sec.
MEC on motherboard
A Memory Expansion Card may be used to increase memory size configurations, which are required for
most server and workstation designs. The Intel 860 chipsets provide memory repeater hubs that allow for
this memory expandability. IWILL MEC card allowsfor memory support of up to 4GB.
ECC Memory
ECC memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed, the
BIOS support both ECC and non-ECC modes. ECC mode is enabled in the Configuration Manager program.
The BIOS automatically detects if ECC memory is installed.
The Configuration Manager program provides an option for enabling and disabling ECC mode.
Whenever ECC mode is selected in Configuration Manager, a small performance difference may occur.
Memory Installation
The MEC8 containsTWO memory channels, in which a total of eight RIMMs banks. When using only four
RIMMs, you must install a Continuity Rambus Inline Memory Module (CRIMM) in those slots that do not
contain RIMMs.
You must first populate J8 and J4 and J7 and J3.
Below illustration show the correct method for installing RIMMs.
Here are the steps of memory installation.
a. Install the Rambus module on the slot of MEC8, see figure down below.
Notice where the key pin is, or it may not be installed.

-13 -
b. If there is any CRIMM module will be installed, it is recommended that the CRIMM module
should be installed near the terminators, see the figure down below.
c. The minimum memory installation we suggested is four exactly the same modules with
four CRIMM modules.
There are two possible memory installations which we do not recommend using two
rambus modules with two CRIMM modules.
d. Install the MEC8 on the motherboard.

CRIMMs must be installed in unpopulated RIMM connectors for the motherboard to boot. RIMMs
must be installed as described in above table or the motherboard will not boot. The memory
must be the same size, density, type, and speed.
Using the encoded part numbers on the RIMMs is the best way to determine if the parts are
the same.

4 Intel 860Chipset
The components of the Intel 860 Chipset on DX400-SNconsists of the following devices:
·82860 Memory Controller Hub (MCH)
·82801BA I/O Controller Hub (ICH2)
·82802 AB Firmware Hub (FWH).
The chipset provides the host bus, memory, AGP, and I/O interfaces.
Intel 860 Chipset Block Diagram
AGP
AGP is a high-performance interconnect for graphic-intensive applications, such as 3D
applications. AGP is independent of the PCI bus and is intended for exclusive use with graphical display
devices. AGP provides these performance features:
* Pipelined-memory read and writes operations that hide memory access latency
* Demultiplexing of address and data on the bus for near-100 percent bus efficiency
* AC timing for 133 MHz data transfer rates (AGP 2X), allowing data throughput of 533 MB/sec
* AC timing for 266 MHz data transfer rates (AGP 4X), allowing data throughput of 1064 MB/sec
AGP Pro50
AGP Pro50 universal add-in card connector is provided on the motherboard. It will accommodate both AGP
and AGP Pro50 cards with a maximum power requirement of 50 Watts.
It is an extension to the AGP interface specification and is designed to meet the needs of advanced
workstation graphics. The new specification is primarily designed to deliver additional electrical power to the
graphics add-in cards.
The AGP Pro universal connector on the DX400-SN motherboard is designed to deliver up to 50 Watts of
electrical power.
The DX400-SN isdesigned to support AGP 1.5V add-on cards only!
Do Not Use 3.3V add-on cards.

-18 -
Universal Serial Bus
The motherboard has four Universal Serial Bus (USB) ports and two USB headers; one USB peripheral can
be connected to each port. For more than two USB devices, an external hub can be connected to either port.
The four USB ports are implemented with stacked back panel connectors. An additional USB riser is required
to co-work with the two USB headers.
The motherboard fully supports the universal host controller interface (UHCI) and uses UHCI-compatible
software drivers.
USB features include:
* Self-identifying peripherals that can be plugged in while the computer is running
* Automatic mapping of function to driver and configuration

-19 -
* Support for isochroous and asynchronous transfer types over the same set of wires
* Support for up to 127 physical devices
* Guaranteed bandwidth and low latencies appropriate for telephony, audio and other applications
* Error-handling and fault-recovery mechanisms built into the protocol
The USB controller provides enhanced support for the Universal Host Controller Interface (UHCI). This includes support that allows
legacy software to use a USB-based keyboard and mouse. The ICH2 is USB Revision 1.1 compliant. The ICH2 contains two USB Host
Controllers. Each HostController includes a root hub with two separate USB ports each, for a total of 4 USB ports.
IDE Support
The motherboard has two independent bus-mastering IDE interfaces. These interfaces support:
* ATAPI devices (such as CD-ROM drives)
*ATA devices using the single-word DMA 0, 1, and 2 and multiword DMA 1 and 2, PIO 0-4

-20 -
The BIOS supports logical block addressing (LBA) and extended cylinder head sector (ECHS)
translation modes. The drive reports the transfer rate and translation mode to the BIOS.
The motherboard supports laser servo (LS-120) diskette technology through its IDE interfaces.
The LS-120 drive can be configured as a boot drive.
The motherboard allows connection of an LS-120 compatible drive and a standard 3.5-inch diskette drive..
The ICH2 supports the IDE controller with two sets of interface signals (Primary and Secondary). It supports
the Ultra ATA/33, Ultra ATA/66 and Ultra ATA/100 protocols. Ultra ATA66 and Ultra ATA/100 are similar to the
Ultra ATA/33 scheme and are intended to be device driver compatible. The Ultra ATA/66 logic clocks at 66
MHz and can move 16bit of data every two clocks, and the Ultra ATA/100 logic clocks at 100MHz can move
16-bit of data every two clock (for a maximum of 100 MB/s)
Real-Time Clock, CMOS SRAM, and Battery
The real-time clock is compatible with DS1287 and MC146818 components. This device provides a
time-of-day clock and a multi-century calendar with alarm features and century rollover. The real-time clock
supports 256 bytes of battery-backed CMOS RAM in two banks that are reserved for BIOS use.
The time, date, and CMOS values can be specified in the Bios Setup. The CMOS values can be returned to
their defaults by using the Bios Setup. An external coin-cell battery powers the real-time clock and CMOS
memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three
years. When the computer is plugged in, the standby current from the power supply extends the life of the
battery.
The clock is accurate to +/-13 minutes/year at 25ºC with 3 VSB applied.
