PROCESSOR (DUAL)
Intel® Pentium®
III microprocessors (FC-PGA) at 600EBMHz - 1.26GHz.
CHIP SET
ServerWorks ServerSet™ III LE
chip set supports higher Front Side Bus bandwidth at
133MHz, with full support for ECC on the memory bus.
Supports single-bit error correction, with multiple-bit
error detection.
FRONT SIDE BUS
The ServerWorks ServerSet III LE supports
speeds of 133MHz. The Front Side Bus provides a path
for transferring data between main memory/chip set and
the microprocessors.
ISA BUS
Provides ISA Bus interface to backplanes
for legacy ISA slots.

BIOS (FLASH)
AMI 7.0 BIOS 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. Custom
BIOSs available.
SYMMETRIC MULTIPROCESSING (SMP)
The dual Pentium III processor-based
design allows the operating system to assign tasks on
demand to the next available processor. SMP uses applications
which are divided into threads which can run concurrently
on any available processor.
CACHE MEMORY (L2)
The Pentium III processor includes
an integrated on-die, 256K or 512K 8-way set associative
level two (L2) cache with a 256-bit wide bus. The processor
also includes a 16K level one (L1) instruction cache
and 16K L1 data cache. These cache arrays run at the
full speed of the processor core.
SDRAM MEMORY
The SDRAM interface consists of two
dual in-line memory module (DIMM) sockets and supports
auto detection of memory up to 2GB of Synchronous DRAM
(SDRAM) memory. The DIMM memory is PC-133 compliant
for a 133MHz Front Side Bus, which means that it complies
with IBM's PC133 SDRAM Registered DIMM Design specification.
Uses industry standard 72-bit (ECC) wide gold finger
DIMM DRAM in two 168-pin DIMM sockets.
ERROR CHECKING AND CORRECTION
The memory interface supports ECC
modes via BIOS setting for multiple-bit error detection
and single-bit error correction.
PCI LOCAL BUS INTERFACE
The SLE provides on-board Primary
and Secondary PCI Bus interfaces. Both Primary and Secondary
bus interfaces provide a sixteen deep I/O cache and
a four deep request queue for PCI to Memory cycles.
Primary PCI Interface: The Primary PCI interface is
32-bit, which runs at 33MHz and supports on-board SCSI,
video and dual Ethernet interfaces.
Secondary PCI Interface: The Secondary PCI interface
is 32/64-bit, operating at 33/66MHz, and drives PICMG®
compliant PCI/ISA passive backplanes.
UNIVERSAL SERIAL BUS (USB)
Supports two USB 1.0 ports for serial
transfers at 12 or 1.5Mbit/sec. The Universal Serial
Bus is an interface allowing for connectivity to many
standard PC peripherals via an external port.

SYSTEM HARDWARE MONITOR
Provides monitoring of system voltages,
temperature and fan speed.
FLOPPY DRIVE INTERFACE
Supports up to two floppy disk drives
in combinations of 360K to 2.88MB.
SUPER VGA INTERFACE
The Intel 69030 video interface has
4MB of on-chip memory and supports pixel resolutions
up to 1280 x 1024 x True Color non-interlaced. Software
drivers are available for most popular operating systems.
SERIAL INTERFACE
Two high-speed FIFO (16C550) serial
ports with independently programmable baud rates. Each
serial port has BIOS selectable addressing.
PCI 10/100BASE-T ETHERNET INTERFACE
(DUAL)
The dual PCI Ethernet interfaces (Intel
82559) support 10/100Base-T via RJ-45 connectors on
the board's I/O bracket. The interfaces are compliant
with IEEE 802.3 and PCI Local Bus 2.1 Specifications.
Link status and activity LEDs are on the I/O bracket.
Software drivers are available for most popular operating
systems..
PCI ULTRA3 SCSI INTERFACE
The Ultra3 SCSI interface is a PCI
Bus Master device using the QLogic ISP10160A SCSI controller,
which supports Ultra3 SCSI maximum throughput of 160MB
per second. Ultra 160 drives are supported. Enable/disable
active termination is provided with terminator voltage
protected by self-resetting fuses. Software drivers
are available for most popular operating systems.
PCI EIDE ULTRA DMA/33 INTERFACE
(DUAL)
Dual high performance PCI Bus Master
EIDE interfaces are capable of supporting up to four
IDE disk drives in a master/slave configuration. Supports
Ultra DMA/33 with synchronous DMA mode transfers up
to 33MB per second.
WATCHDOG TIMER
The software controlled watchdog timer
monitors system activity and generates a reset pulse
in the event of a time-out.
ENHANCED BI-DIRECTIONAL PARALLEL
INTERFACE
Compatible with PC/AT bi-directional
parallel port and supports EPP and ECP modes. The ECP
mode is IEEE 1284 compliant. Parallel port has BIOS
selectable addressing.
KEYBOARD AND PS/2 MOUSE INTERFACES
The keyboard and PS/2 mouse interfaces
are combined into one connector. These interfaces are
protected by self-resetting fuses and are accessible
via a Y cable or off-board cabling.
POWER FAIL DETECTION
Issues a hardware reset when on-board
voltage drops below 4.75 volts.
BATTERY
Built-in lithium battery for ten years
of data retention for CMOS memory.
