OVERVIEW
This Mainboard is a revolutionary high performance personal computer
mainboard. It is the ATX form-factor with both Slot 1 and Socket 370 on the
board for different package of processors. VIA693 or VIA693A chipset is chosen
as the system core logic of the mainboard to give the most outstanding
performance and reliability. It is designed for 233, 266, 300 , 333, 350, 366, 400,
433, 450, 466, 500, 550, 600MHz and higher speed Pentium™ II , Pentium™ !!!
and Celeron™ processors
This mainboard is designed by using either VIA693 or VIA693A system chipset.
The difference is shown as following:

This mainboard two channel “PIO” and “Ultra DMA33/66 Bus Master” mode PCI
IDE ports are built on the mainboard to support the most updated Ultra DMA 66
HDD. One Floppy Disk controller, two high speed Serial ports (UARTs), one
multi-mode Parallel port, one PS/2™ mouse port, one IR interface and two USB
ports is designed on the board for wide variety of peripheral connection.
The ALS300 PCI sound chip is designed on board (sound interface is optional on
the board). The ALS300 has built-in 2D/3D Sound Effect Processor, Enhanced
normal & digital Game port, MPU-401 MIDI controller, ALSFM Synthesizer.
When you find the ALS300 sound interface (CN18) installed on the mainboard,
you don't have to purchase another sound card because there is the 3D audio
interface on this mainboard.
Pentium™ II, Pentium™ !!! and Celeron™ are the 64-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.
