PROCESSOR
Intel Pentium III microprocessor at
600EMHz - 1.0GHz
Intel Celeron microprocessor at 433MHz - 850MHz
PROCESSOR PACKAGE
Pentium III or Celeron processor in
a low-profile Socket 370 compatible package
CHIP SET
Intel 440BX AGPset with the Accelerated
Graphics Port (AGP) interface
SYSTEM/MEMORY BUS
Intel 440BX AGPset supports the system/memory
buses at both 66MHz and 100MHz speeds. The 100MHz system/memory
buses provide a higher bandwidth path for transferring
data between main memory/chip set and the processor.
CONCURRENT PCI
Maximizes system performance with
simultaneous processor, PCI and AGP Bus activities.
It includes multi-transaction timing, enhanced write
performance, a passive release mechanism and support
for PCI 2.1 compliant delayed transactions.

BIOS (FLASH)
AMI Hi-Flex 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.
CACHE MEMORY (L2)
Pentium III - A 256K integrated on-die
Advanced Transfer Cache. The cache is 256-bit wide,
8-way set associative cache running at full processor
core frequency.
Celeron - A 128K integrated on-die 64-bit wide, non-blocking
cache.
DRAM MEMORY
The SDRAM interface consists of two
dual in-line memory module (DIMM) sockets and supports
auto detection of memory up to 512MB of Synchronous
DRAM (SDRAM) memory. Minimum memory size is 8MB. The
DIMM memory is PC-100 compliant for all speeds, which
means that they comply with Intel's PC SDRAM specifications.
Uses industry standard 64-bit (non-ECC) or 72-bit (ECC)
wide gold finger DIMM DRAM in two 168-pin DIMM sockets.
MEMORY HOLE
Supports a 1MB memory hole option
at 15-16MB.
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
Fully compliant with the PCI Local
Bus 2.1 Specification. This board has optimized the
PCI interface to allow the processor to sustain the
highest possible bandwidth (greater than 100MB/sec sustained)
and supports PCI-to-PCI bridge technology.
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.
AGP SUPER VGA INTERFACE
The 69000 video interface is an Accelerated
Graphics Port (AGP) device with 2MB of on-chip memory.
AGP is designed to off-load the PCI Bus by allowing
graphics data to move directly from system memory. The
interface supports pixel resolutions up to 1280 x 1024
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
The PCI Ethernet interface (Intel
82559) supports 10/100Base-T via an RJ-45 connector
on the board's I/O bracket. The interface is 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 ULTRA WIDE SCSI INTERFACE
The SCSI interface is a PCI Bus Master
device using the Adaptec AIC-7880 chip. Supports Ultra
Wide SCSI operation up to 40MB per second and bursts
data to the host at full PCI speeds. 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 Type 4 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.
PS/2 MOUSE INTERFACES
Compatible with a PS/2-type mouse.
Accessible via the I/O bracket or off-board cabling.
Mouse voltage is protected by a self-resetting fuse.
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.
