OVERVIEW
This Mainboard is a revolutionary high performance personal computer
mainboard. It is the ATX form-factor with the Socket 370 CPU connector
designed on the board for the Pentium™ !!! and Celeron™ processors. VIA
VT82C694X and VT82C686A chipsets are chosen as the system core logic of the
mainboard to give the most outstanding performance and reliability. VIA
VT82C694X is the energy efficient chipset and it supports the system front side
bus speed from 66MHz, 100MHZ to 133MHz for various Celeron™ and
Pentium™ !!! processors
VIA VT82C686A is a high integration, high integration, power-efficient and high
compatibility device which supports Intel and non-Intel processors to PCI bridge
functionality to make a complete PC99-compliant PCI/ISA system.. Beside the
ISA extension bus functionality, the VT82C686A provides two channels of "PIO”
and "Ultra DMA33/66 Bus Master” mode PCI IDE ports to support the most
updated Ultra DMA 66 HDD. There are one Floppy Disk controller, two high
speed Serial ports (UARTs), one multi-mode Parallel port, one
PS/2™ mouse
port, one IR interface and four USB ports designed on the board for wide variety
of peripheral connection.
There is the full featured AGP (Accelerated Graphics Port) slot designed on the
mainboard which supports the 4X AGP mode. When you have the 4X AGP
display card installed on the mainboard, it will enhance the system display
performance tremendously. There is also the 3D audio interface integrated on the
mainboard (694TX has the audio interface designed on the board, but 694TXL
does not support audio interface and AMP slot.). When the audio interface is
installed on the mainboard, you need not invest any on the audio interface card.
Simply have the speaker connected to the audio connector (CN18) on the
mainboard and you will have the 3D sound effect in your PC system.
Note
Pentium™ !!! and Celeron™ are the 32-bit processors with RISC technology,
which offers several key features such as built-in 512K/256/128K L2 cache, 12-
stage super-pipeline architecture, out of order execution … etc. In order to
optimize of its capabilities and performances, the 32-bit Operating System (such
as Windows® and OS/2™) and 32-bit applications are recommended.
