Chapter 2 INSTALLATION
2-1 Motherboard Description
The motherboard is designed with the Intel 82440LX PCI chipset
which is developed by Intel Corporation to fully support the
Pentium II Processor PCI/ISA system. The Intel 82440LX 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 16Byte 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 8MB of system memory and a
maximum of 512MB SDRAM, 1GB EDO RAM.
The motherboard supports standard Fast Page (FP), EDO (Extended
Data Output), or SDRAM (Synchronous DRAM). The motherboard
provides three 168-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.

2-4 Central Processing nit (CP )
The motherboard provides a SLOT 1 for Pentium II 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.
NOTE Without a fan, the CPU can overheat and cause damage
to both the CPU and the motherboard.

Chapter 2 INSTALLATION
To install a CPU, locate the SLOT 1. Insert the CPU with the correct
orientation. you should have a CPU fan that will cover the face of the
CPU.

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 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.
