Chapter 1 Introduction
1-1 Main Board Overview
The main board is a new-generation PentiumÆ II and PentiumÆ III main board
based on VIA VT82C693/693A chipset. The main board has integrated the latest
advances in processor, memory, I/O technologies into an ATX form factor.
The main board utilizes VIA 693/693A chipset designed for PentiumÆ II and
PentiumÆ III CPUs and supports new architects such as high-speed AGP graphic
port, SDRAM, Ultra DMA/66, bus master IDE and USB port. It has three Dual
In-line Memory Modules (DIMM) which can be installed with SDRAM memory
. The memory subsystem supports up to either 384 MB ( SDRAM) or 384 MB
(EDO RAM). The main board using the Slot 1 socket, accepts IntelÆ PentiumÆ
II (66/100 MHz) & PentiumÆ III(100/133 MHz) processors. Built-in second
level (L2) cache in CPU, there is no cache necessary in this system board.
The main board has implemented VIA VT82C686A high performance I/O
Controller utilizes with fully Plug and Play device which supports 2.88 MB
Floppy, Dual 16550 Compatible (with 16 bytes FIFO, up to 460K baud rate)
Serial Port, ECP (Enhanced Capabilities Port), EPP (Enhanced Parallel Port)
parallel port, Infrared IrDA (HPSIR), Amplitude Shift Keyed IR. (ASKIR) port
and Audio.
The main board supports 4*PCI, 2*ISA, 1*A.G.P and 1*AMR. (three PCI Bus
Mastering slots & 1 PCI Bus Slave slot) for highest performance I/O add-on
adapter cards.

The main board is also strengthened with Power Management Wake up Event
such as ìWOL (Wake up on LAN),î ìModem ring onî which are the new
inventions to enable PCs to be turned on over the network. These are also key
benefits in PC operation, asset management, new system setup and power
conservation.
In conclusion, the main board is a combination of the highest in performance,
flexibility, efficiency, and ease of use that meets a variety of price/performance
levels. The main board is an ideal platform for the increasing requirements of
todayís and futureís desktop application.

1-2 Reference For PentiumÆ II CPUs
The main board supports Intel Æ PentiumÆ II and PentiumÆ III
microprocessors. The PentiumÆ II and Pentiumô III processors deliver more
performances than previous generation processors (such as PentiumÆ, PentiumÆ
MMXô, etc...) through an innovation called Dynamic Execution Architecture.
It is improved by 3D visualization and interactive capabilities required by present
high-end commercial and technical applications and futureís emerging
applications as well.
Below is the reference for PentiumÆ II CPUs accomodating this main board.

•Green function: Complied with APM (Advanced Power Management)
•ATX form factor
The ATX form factor has been defined to address four major areas of
improvement required of todayís predominant form factors.
!Enhance PC ease-of-use with all built-in I/O connector
!Better support for current and future I/O
!Reduce total system cost
!Better support for future processor technology
ATX is an evolution of the popular Baby-AT form factor. By mounting the
power supply on its side, the processor is relocated away from the expansion
slots, and the longer side of the board is used to host more on-board I/O
connector; this placing of I/O on the board reduces cabling inside the box,
lower costs, and improves reliability and ease-of use. A flexible I/O panel
allows ATX to support all current and future I/O requirements. The ATX
power supply will directly suck the air out of chassis that will save the cost of
a secondary fan in the system. System cost is further reduced by the higher
integration of PC components onto the system board itself, saving materials,
inventory holding, and assembly cost.
•Power supply regulation
Onboard switching voltage that supports appropriate power to the CPU and
future upgraded CPUs.

•Over-current protection circuit
With AIC 1569CS AH10 (protect CPU from accident short circuit), if system
current is over-loaded, the system will break down to protect direct damage of
the main board.
