OVERVIEW
This Mainboard is a high performance personal computer mainboard. It is the AT
form-factor with Socket 370 on the board for socket type Celeron™ Processors.
VIA 693 and 596 chipsets are chosen as the system core logic to give the most
outstanding performance and reliability. It is designed for 300, 333, 350, 366, 400,
433, 450, 466, 500, 550MHz and higher speed socket type Celeron™ processors.
The chipset installed on this mainboard will be either
VIA 693 with 596A or
VIA
693 with 596B chipsets. The difference between these two chipset are shown in
the following table:

This mainboard has two channels of “PIO” and “Ultra DMA33 ( or Ultra DMA66)
Bus Master” mode PCI IDE ports built on the mainboard to support the most
updated IDE devices. One Floppy Disk controller interface, two high speed Serial
ports (UARTs), one multi-mode Parallel port, one PS/2™ mouse port, one IR
interface and two USB ports are designed on the board for wide variety of
peripheral connection.
The ESS Solo-1 (ES1938S) PCI sound chip is designed on board (ESS sound chip
is optional on the board). 3-D stereo effects processor, 16-bit stereo wave ADC
and DAC, 16-bit stereo music DAC, MPV-401 UART mode serial port dual game
port and ESFM
ä
music synthesizer is built in the ES1938S audio chipset. When
you find the ES1938S sound interface (CN18) installed on the mainboard, you
don't have to purchase another sound card because there is the 3D audio interface
on your mainboard.
The Celeron™ are the 32-bit processors with RISC technology, which offers
several key features such as built-in 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.
