2.2 CPU

The mainboard supports AMD® Athlon64 processor. The mainboard
uses a CPU socket called Socket-939 for easy CPU installation. When you are
installing the CPU, make sure the CPU has a heat sink and a cooling fan
attached on the top to prevent overheating. If you do not have the heat
sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.

For the latest information about CPU, please visit http://www.msi.com.tw/
program/products/mainboard/mbd/pro_mbd_cpu_support.php.

MSI Reminds You...

Overheating

Overheating will seriously damage the CPU and system, always
make sure the cooling fan can work properly to protect the CPU
from overheating.

Replacing the CPU

While replacing the CPU, always turn off the ATX power supply or
unplug the power supply’s power cord from grounded outlet first
to ensure the safety of CPU.

PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug & Play)
feature. PCI, or Peripheral Component Interconnect, is a system which allows I/O
devices to operate at speeds nearing the speed the CPU itself uses when communi­cating with its special components. This section covers some very technical items
and it is strongly recommended that only experienced users should make any changes
to the default settings.

Clear ESCD

The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Random Ac­cess Memory) is where the BIOS stores resource information for both PNP and non­PNP devices in a bit string format. When the item is set to [Yes], the system will reset
ESCD NVRAM right after the system is booted up and then set the setting of the item
back to [No] automatically.

Primary Graphics Adapter

This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
[Auto] The system will automatic detect the current graphic card.
[PCI Mode] The system initializes the installed PCI VGA card first.

Chapter 4 - BIOS Setup

PCI Latency Timer

This item controls how long each PCI device can hold the bus before another takes
over. When set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values. Setting options: [32], [64], [96], [128].

IRQ Resource Setup

Press <Enter> to enter the sub-menu and the following screen appears.

IRQ 3/4/5/7/9/10/11/14/15

These items specify the bus where the specified IRQ line is used.
The settings determine if AMIBIOS should remove an IRQ from the pool of avail­able IRQs passed to devices that are configurable by the system BIOS. The
available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must
be removed from the IRQ pool, the end user can use these settings to reserve
the IRQ by assigning an [Reserved] setting to it. Onboard I/O is configured by
AMIBIOS. All IRQs used by onboard I/O are configured as [Available]. If all IRQs
are set to [Reserved], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9
will still be available for PCI and PnP devices. Available settings: [Reserved] and
[Available].

MSI Reminds You...

IRQ (Interrupt Request) lines are system resources allocated to I/O
devices. When an I/O device needs to gain attention of the operating
system, it signals this by causing an IRQ to occur. After receiving the
signal, when the operating system is ready, the system will interrupt
itself and perform the service required by the I/O device.

4-19

DMA Resource Setup

Press <Enter> to enter the sub-menu and the following screen appears.

DMA Channel 0/1/3/5/6/7

These items specify the bus that the system DMA (Direct Memory Access)
channel is using.
The settings determine if AMIBIOS should remove a DMA from the available
DMAs passed to devices that are configurable by the system BIOS. The avail­able DMA pool is determined by reading the ESCD NVRAM. If more DMAs must be
removed from the pool, the end user can reserve the DMA.
