OVERVIEW

This Mainboard is a high performance Pentium™ II personal computer mainboard with
100MHz ultra high Front Side Bus (FSB) frequency. It is designed for the high
performance Pentium™ II or Celeron™ processor 233 MHz, 266 MHz, 300 MHz,
333MHz, 366MHz, 400MHz, 450MHz and up to 500MHz. This mainboard is the AT
form-factor with A.G.P. (Accelerated Graphics Port) and PCI Local Bus on board,
designed based on the Intel® 82440BX or 82440ZX AGPset™ system chipset.
The system core logic on this mainboard will be either the Intel 440BX or 440ZX
chipset The difference between BX and ZX on this mainboard is shown as following:
DIMM SOCKET
ECC
Two channels "PIO" and "Ultra DMA/33 Bus Master" mode PCI IDE ports, one
Floppy Disk control port, two high speed Serial ports (UARTs) and one multi-mode
Parallel port and supports PS/2™ mouse, IR and USB ports are built on the board..
The Pentium™ II and Celeron™ Processor are the 64-bit processors with RISC
technology, which offer several key features such as built-in 128/256KB/512KB L2
cache (some Celeron does not have L2 cache), 12-stage super-pipeline architecture, out
of order execution .... etc. In order to optimize of its performances, the 32-bit Operating
System (such as Windows® NT and OS/2™) and 32-bit applications are recommended.
The Accelerated Graphics Port (A.G.P.) on the mainboard is designed for AGP 3D
video display card. Unlike PCI-based display cards, the AGP technology provides
lightning data throughput to fully facilitate the 3-Dimensional and multimedia graphics
display. The data transfer rate on AGP can be up to 133Mhz and which is much faster
than the traditional 33MHz PCI VGA card.
