2-1 Motherboard Description
The motherboard is designed with the VIA VT 2C597AT PCI chipset
which is developed by VIA Corporation to fully support the
Pentium Processor PCI/ISA system. The VIA VT 2C597AT PCI
chipset provides increased integration and improved performance
designs. The chipset provides an integrated IDE controller with two
high performance IDE interfaces for up to four IDE devices (hard
devices, CD-ROM device, etc). The Super I/O controller provides the
standard PC I/O function: floppy interface, two 16-Byte FIFO serial
ports and EPP/ECP capable parallel port.
Care must be taken when inserting memory modules, inserting CPU
or even plugging PCI card into associated slots to avoid damaging any
circuits or sockets on board. A cooling fan is strongly recommended.
The motherboard supports minimum of MB of system memory and a
maximum 1GB RAM.
The motherboard supports standard Fast Page (FP), EDO (Extended
Data Output), or SDRAM (Synchronous DRAM). The motherboard
provides two 16 -pin DIMM.
The board also supports onboard two PCI IDE connectors, and detects
the IDE hard disk type by the BIOS utility which is automatic. The
system also supports Award Plug & Play BIOS for the ISA and PCI
cards.

2-3 System Memories
This motherboard supports two 72-pin Single Inline Memory
Modules (SIMM) of 4MB, MB, 16MB, 32MB, and/or 64MB to
form a memory size between MB to 256MB. The DRAM can be
either 60ns or 70ns Fast Page Mode (FPM, Asymmetric or
Symmetric), Extended Data Output (EDO). SIMMs must be installed
in pairs so that each bank contains two of the same size and same
model memory modules.
This motherboard also supports two Dual Inline Memory
Modules (DIMM’S), The Dual Inline Memory Module (DIMM) must
be 3.3 Volt Unbuffered Synchronous DRAM (SDRAM) or Exteded
Data Output (EDO) DRAM of either 16, 32, 64, or 12 MB to form a
memory size between 16MB to 256MB.
Note :
1. Install memory in any combination as next page :
2. Do not mixed use SIMM and DIMM

2-4 Central Processing Unit (CPU)
The motherboard provides a Socket 7 for Pentium CPU. The CPU
should have a fan attached to it to prevent overheating. If your CPU
did not come with a fan, then purchase a fan before you turn on your
system.
To install a CPU, locate the Socket 7 (U14). Insert the CPU with the
correct orientation. you should have a CPU fan that will cover the face
of the CPU.
NOTE: Without a fan, the CPU can overheat and
cause damage to both the CPU and the
motherboard.

2-5 Expansion Cards & Slots
Assigning DMA Channels for ISA Cards:
Some ISA cards, both Legacy and PnP may also need to use a DMA
(Direct Memory Access) channel. DMA assignments for this
motherboard are handled the same way as the IRQ assignment process
. You can select a DMA channel in the PCI and PnP configuration
section of the BIOS Setup utility.
NOTE: 1, Choose “Legacy ISA” for those IRQ’s and
DMA’s you wish to reserve for Legacy
(Non-PnP) ISA expansion cards in “IRQ xx
Used by ISA” and “DMA x Used By ISA”
of the PnP and PCI Setup in the BIOS
Software section, otherwise conflicts may
occur.
This motherboard provide an AGP (Accelerated Graphics Port)
slot to support a new generation of graphics cards with ultra-high
memory bandwidth. (Note : For the detail of AGP to see appendix)

You can enable the parallel port (LPT1) and choose the IRQ
through BIOS Setup on Onboard Parallel Port.
4. Serial Ports (COM1, COM2, 10-pin Pin header).
The two serial (COM1 & COM2) ports can be used for
pointing devices or other serial devices. See “Onboard Serial

5. AT & ATX Power Supply Connectors
CN3 is a standard 12-pin AT-type or PS/2 type connector. Be
sure to attach the two connectors with the two black wires
next to each other, at the center. CN4 is a standard ATX-type
power connector. (The ATX power connector can only be
inserted the correct way.)
NOTE:
To prevent electrical spikes, make sure that the power
supply is not connected to an outlet when making or removing
connections. Power supplies contain power reserves which
can damage electrical components.
