OVERVIEW
The
PT-6IL
is a high performance personal computer mainboard designed for the
Pentium™ II processor.
PT-6IL
is an ATX form-factor mainboard with A.G.P.
(Accelerated Graphics Port) and PCI Local Bus on board. It is designed based on the
Intel® 82440LX AGPset™ system chipset and Winbond® I/O chipset, built-in two
channel “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. It is designed to fit a high performance
Pentium™ II (S.E.C. Cartridge) processor 233 MHz, 266 MHz , 300 MHz and 333MHz
based solution for high-end and true GREEN-PC computer systems.
The Pentium™ II Processor is a 64-bit processor with RISC technology, which offers
several key features such as built-in 256KB/512KB L2 cache, 12-stage superpipeline
architecture, out of order execution .... etc. In order to optimize of its capabilities and
performances, the 32-bit Operating System (such as Windows® NT and OS/2™) and
32-bit application are recommended.
The Accelerated Graphics Port (A.G.P.) on the PT-6IL 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.
The AGP is a new video display technology and it requires device driver or new
Operating System to enable this accelerated graphic feature. Windows® 98 supports
AGP directly but Windows® 95 still need the appropriate device drivers to support
AGP feature. Please don’t worry about the device driver, because you can always find
the device driver included in the AGP card. Regarding the definition of AGP interface
and its functionality, please refer to the latest
A.G.P. Interface Specification
