HYPER-THREADING TECHNOLOGY
Intel's Hyper-Threading technology
makes the Xeon processor appear as two logical processors.
This feature delivers faster program execution by enabling
simultaneous instruction processing using the two logical
processors.
CHIPSET
Intel's E7500 Chipset provides support
for a faster system bus, DDR memory with ECC and high-speed
I/O expansion.
SYSTEM BUS
The Intel E7500 Chipset supports a
system bus speed of 400MHz.

BIOS (FLASH)
AMIBIOS8 with built-in advanced CMOS
setup for system parameters, peripheral management for
configuring
on-board peripherals, PCI-to-PCI bridge support and
PCI interrupt steering. Supports flash devices for BIOS
upgrading via floppy interface. Also provides integrated
support for USB mass storage devices such as USB
CD-ROM, CD-RW, etc. Custom BIOSs are available upon
request.
CACHE MEMORY
The Xeon processor supports a 512K
integrated on-die Advanced Transfer Cache (L2). The
cache is an 8-way set associative cache running at full
processor core frequency. The Execution Trace Cache
(L1) is a 12K data cache that stores thousand of decoded
micro-operations. The purpose of this L1 cache is to
remove decoder latency from the processor's main execution
path. The net result is increased processor performance.
DDR200/266 MEMORY
Double Data Rate (DDR) memory improves
memory data speed performance in data-intensive applications.
The DDR200/266 interface consists of two DDR memory
channels coming from the Memory Controller Hub (MCH)
with each channel connected to a separate memory module
socket. The sockets may contain either PC1600 or PC2100
DIMMs. The DIMM sockets must contain the same size and
type of ECC registered DDR module. The bandwidth of
the DDR200/266 memory interface is 1600MB/s per channel.
ERROR CHECKING AND CORRECTION
The memory interface supports ECC
modes via BIOS setting for multiple-bit error detection
and correction of all errors confined to a single nibble.
PCI BUS INTERFACE
The PCI bus interface supports either
a 32-bit or 64-bit PCI backplane interface running at
either a 33MHz or 66MHz bus speed.
ISA BUS
The XPI provides a 16-bit ISA bus
interface to the backplane for legacy ISA slots.
SYSTEM HARDWARE MONITOR
The Winbond W83783S chip supports
hardware monitoring. The functions monitored are voltage,
fan speed and temperature. The XPI hardware monitor
software allows the user to program the monitor limits
to provide a trigger point for the application software.
This allows the application program to monitor these
trigger points in order to send system alert messages
or perform corrective action.
FLOPPY DRIVE INTERFACE
Supports up to two floppy disk drives
in combinations of 360K to 2.88MB.
SUPER XGA VIDEO INTERFACE
The Intel CHIPS 69030 video interface
has 4MB of on-chip memory and supports pixel resolutions
up to 1280 x 1024. Software drivers are available for
most popular operating systems.
SERIAL INTERFACE
The Super I/O controller supports
two full-function serial ports with independently programmable
baud rates. The controller has two high-speed, NS16C550
compatible, UARTs with Send/Receive 16-Byte FIFOs. The
IRQ for each serial port has BIOS selectable addressing.

DUAL ETHERNET INTERFACES
- 10/100/1000 BASE-T
The XPI's internal PCI-X bus, with
a bus speed of 133HMz, connects to Intel's 82546EB Ethernet
Controller chip. This feature provides high-speed dual
Gigabit Ethernet on LAN ports 1 and 2. The XPI also
supports existing 10Mb or 100Mb per second Ethernet
networks over the same internal PCI-X bus. RJ-45 connectors
located on the I/O bracket provide the mechanical interface
to the Ethernet networks.
EIDE ULTRA ATA/100 INTERFACES
(DUAL)
Dual high-performance PCI Bus Master
EIDE interfaces are capable of supporting up to two
IDE disk drives each in a master/slave configuration.
The interface supports Ultra ATA/100 with synchronous
ATA mode transfers up to 100MB per second.
OPTIONAL I/O EXPANSION
Optional I/O expansion mezzanine cards
connect directly to the XPI's Memory Controller Hub
(MCH) via Intel's Hub Link 2.0 interface. This feature
provides fast (1GB/s) I/O connectivity for mezzanine
expansion cards such as Chassis Plans's H2S2
Dual Ultra160 SCSI interface. Consult Sales for additional
I/O expansion card availability.
WATCHDOG TIMER
The programmable watchdog timer provides
a system reset with a total range of 1ms to 60 seconds.
The programmable increments of the watchdog are 1ms,
10s and 60s.
ENHANCED BI-DIRECTIONAL PARALLEL
INTERFACE
The parallel port interface is compatible
with IBM PC/XT®, PC/AT®,
PS/2™, Enhanced Parallel Port (EPP1.7, EPP1.9)
and Extended Capabilities Port (ECP) modes of operation.
Both the EPP and ECP modes are IEEE 1284 compliant.
The parallel port has BIOS selectable addressing.
KEYBOARD AND PS/2 MOUSE INTERFACES
The mini DIN connector located on
the I/O bracket provides an external interface for a
PS/2 mouse and keyboard. A "Y" adapter plugged into
the mini DIN connector allows the PS/2 mouse and keyboard
to share the same port. Internal PS/2 mouse and keyboard
headers are also available. A self-resetting fuse protects
the +5V line of the keyboard and the mouse.

* From Backplane via PICMG® Connector.
# From ATX12V power supply or equivalent via P4 connector.
The Xeon processor's power requirements created the need
for an additional on-board 4-pin power connector
(P4). This connector requires +12V from an external power
supply that conforms to the ATX12V power specification.
This external power supply should have a minimum wattage
rating of at least 250W. The XPI also requires that 3.3V
be applied to the backplane from the power supply.
POWER FAIL DETECTION
The XPI continuously monitors the incoming +5V and +3.3V
power lines from the system backplane. If the 5V line
drops below 4.75 volt or the 3.3V line drops below 2.97
volt, the XPI issues a hardware-reset command. This
feature helps maintain control and allows the system
to automatically restart. A two-pin header is available
for applications that require an external reset switch.
On-board power lines are also monitored in a similar
fashion.
BATTERY
Built-in lithium battery for data retention of CMOS
memory.
