Overview

The main board utilizes Intel's latest i815EP chipset integrated with new
architects such as high-speed 2X/4X mode AGP interface multiplexed
UDMA66/100, CNR (communication Networking Riser) SDRAM, USB port are
designed to fit INTEL
TM
Coppermine /CyrixIII CPUs.
®
The Intel 815EP Chipset is a high-flexibility chipset designed to extend from the
basic graphics/multimedia PC platform up to the mainstream performance desktop
platform. The chipset consists of a Memory Controller Hub(Intel
I/O Controller Hub(ICH) for the I/O subsystem, and a Firmware Hub(FWH). The
®
Intel 815EP MCH integrates a system memory SDRAM controller that supports a
64-bit 100/133 MHz SDRAM array.
The main board also employs I/O LPC controller utilizing with fully Plug and
Play device and keyboard password setup. It supports 2.88 MB Floppy, Dual
16550 compatible (with 16 bytes FIFO, up to 460K baud rate) serial Port, ECP
(Enhanced Capabilities Port), EPP(Enhanced Parallel Port) parallel port,
SPP(Standard Parallel Port), Infrared IrDA (HPSIR), and Amplitude Shift Keyed
IR. (ASKIR) port and hardware monitor functions too.
The main board contains 5*PCI for highest performance I/O add-on adapter cards.
The system board supports three Bus Mastering Slots for high-performance I/O
add-on cards. It supports Matrix Independent PCI routing for optimal multiple PCI
adapter operations and is PCI 2.2 specification compliant. It supports back to back
sequential CPU to PCI Memory writes to PCI Burst Write for full PCI throughput.
The new CNR Slot is designed to fit C(Communication) N(Networking) R(Riser)
or MR card.
