CHAPTER 2: HARDWARE INSTALLATION

2.1 CENTRAL PROCESSING UNI T (CPU)

Step 1: Pull the lever sideways away from the socket and then raise the

lever up to a 90-degree angl e.

Step 2: Look for the bl ack cut edge on socket, and the white dot on CPU

should point forwards this bl ack cut edge. T he CPU will fit onl y
in th e cor r ec t or i en tation.

6

K8T80-A7

Step 3: Hold the CPU down firml y, and then close the lever to complete

the i nstalla ti on.

Step 4: Put the CPU Fan on t he CPU and buckle it. Conn ect t he CPU

FAN power cable to the JCFAN1. This completes the
installation.

2.3 MEMORY MODULE INSTA LLATION

1. Unlock a DIMM sl ot by pressing the retaining clips outward. Align a
DIMM on the slot such that the notch on the DIMM m atches the

break on the Slot.

2. Insert the DIMM vertically and firml y into the sl ot until the retaining
chip snap back in place and the DIMM is properly seated.

If the system shutdown automatically after power on system for
seconds, that means the CPU protection function has been activated.

When the CPU is over heated, the motherboard will shutdown
automatically to avoid a damage of the CPU, and the system may not

power on again.

In this case, please double check:

1. T he CPU cooler surface i s placed evenl y with the CPU surface.

2. CPU fan is rotated normall y.

3. CPU fan speed i s ful filling with the CPU speed.

After confirmed, please follow steps below to relief the CPU protection

CHAPTER 5: WARPSPEEDER™

5.1 INTRODUCTION

[WarpSpeeder™], a new powerful control utility, features three
user-friendly functions including Overclock Manager, Overvoltage

Manager, and Hardware Monitor.
Wi th the Overclock Manager, users can easily adjust the frequency they

prefer or they can get the best CPU performance wi th just one click. The
Overvol tage Manager, on the other hand, helps to power up CPU core

vol tage and Me mor y v ol tage. The co o l H ar dware Mo ni tor s martly indicates
the temperatures, vol tage and CPU fan speed as wel l as the chi pset

information. Al so, in the About panel , you can get detail descripti ons about
BIOS model and chipsets. In addition, the frequency status of CPU,

mem ory, AGP and PCI along with the CPU speed are synchroni cally
s how n on our ma i n p an el .

Moreover, to protect users' computer systems i f the setting is not
appropriate when testing and results i n system fail or hang,

[WarpSpeeder™] technology assures the sy stem stability by automatically
rebooting the computer and then restart to a speed that i s ei ther the

ori ginal system speed or a suitable one.

5.2 SYSTEM REQUIREMENT

OS Support: Windows 98 SE, Windows Me, Windows 2000, Windows XP
DirectX: DirectX 8.1 or above. (T he Windows XP operating system

includes DirectX 8.1. If you use Wi ndows XP, you do not need to instal l
Dir ec tX 8.1.)

T he Award BIOS™ in stalle d in your co mput er syst em’s RO M (R ead Only Mem ory) is a
custom version of an industry standard BIOS. T his means that it supports Intel P entium

processor input/output system. The BIOS provides critical low-level support for standard
devices such as disk drives and serial and parallel ports.

Adding important has customized the Award BIOS™, but nonstandard, features such as
virus and password protection as we ll as special support for detailed fine-tunin g of the
chipset controlling the entire system.

The rest of this manual is intended to guide you through the process of configuring your
system using Setup.

Plug and Play Support

These AWARD BIOS supports the Plug and Play Version 1.0A specification. ESCD
(Extended System Configuration Data) write is supported.

EPA Gree n PC Support

This AWARD BIOS supports Version 1.03 of the EPA Green PC specification.

APM Support

These AWARD BIOS supports Version 1.1&1.2 of the Advanced Power Management

7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed of
the CPU itself uses when communicating with its own 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 settin gs.

Figure 7. PnP/PCI Configurations



7.1 PNP OS Installed

Wh en set to YES, BIOS will on ly init ialize the P nP c ards used for th e bo ot sequence (VGA,
IDE, SCSI). The rest of the cards will be initialized by the PnP operating system like

Window™ 9 5. When set to N O, BIOS wil l init ia l ize all th e P nP cards. For non-P nP
operating systems (DOS, Netware™), this option must set to NO.
The Choices: No (default), Yes.

32

K8T80-A7 BIOS Setup

7.2 Reset Configuration Data

The system BIOS supports the PnP feature which requires the system to record which
resources are assigned and protects resources from conflict. Every peripheral device has a
node, which is called ESCD. This node records which resources are assigned to it. The
syst em needs to rec ord and upda te ESCD to th e memory locat ions . T hese locations (4 K)
are reserved in the system BIOS. If the Disabled (default) option is chosen, the system‘s
ESCD will update only when the new configuration varies from the last one. If the Enabled

option is chosen, the system is forced to update ESCDs and then is automatically set to the
“D isab led” m ode.
The above settings will be shown on the screen only if “Manual” is chosen for the resources
controlled by function.

Le gacy is t he term, which signif ies that a re sou rce is assigned to the ISA Bus an d provides
non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is assigned to the PCI
Bus or provides for ISA PnP add-on cards and peripherals.

The Choices: Disabled (default), Enabled.

7.3 Resources Co ntrolle d By

By Choosing “Auto(ESCD)” (default), the system BIOS will detect the system resources
and automatically assign the relative IRQ and DMA channel for each peripheral.By

Choosing “Manual”, the user will need to assign IRQ & DMA for add-on cards. Be sure
that there are no IRQ/DMA and I/O port conflicts.

7.4 IRQ Resources

This submenu will allow you to assign each system interrupt a type, depending on the type
of device using the interrupt. When you press the “Press Enter” tag, you will be directed to
a submenu that will allow you to configure the system interrupts. This is only
configurable when “Resources Controlled By” is set to “Manual”.

IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device
IRQ-5 assigned to PCI Device

IRQ-7 assigned to PCI Device
IRQ-9 assigned to PCI Device
IRQ-10 assigned to PCI Device
IRQ-11 assigned to PCI Device
IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device

IRQ-15 assigned to PCI Device

7.5 PCI / VGA Palette Snoop

Choose Disabled or Enabled. Some graphic controllers which are not VG A compatible
take the output from a VGA controller and map it to their display as a way to provide boot
information and VGA compatibility.

However, the color information coming from the VGA controller is draw n from the palette
table inside the VGA controller to generate the proper colors, and the graphic controller

needs to kno w what is in the palette of the VGA c ontroller. To do this, the non-VGA
graphic controller watches for the Write access to the VGA palette and registers the snoop
data. In P CI based systems, where the VGA controller is on the PCI bus and a non-VGA

graphic controller is on an ISA bus, the Write Access to the palette will not show up on the
ISA bus if the PCI VGA controller responds to the Write.

In this c ase, the PCI VGA controller shou ld n ot respond to the Write, it should only snoop
the data and permit the access to be forwarded to the ISA bus. The non-VGA ISA graphic
controller can then snoop the data on the ISA bus. Unless you have the above situation,
you should disable th is option.

Disabled (default) Disables the function.
Enabled Enables the function.

7.6 Assign IRQ For USB

This item allows the users to choose which IRQ to assign for the USB.

The Choices: Enabled (default), Disabled.

This item allows you to select CPU Clock, and CPU over clocking.
If unfortunately, the system’s frequency that you are selected is not
functioning, there are two methods of booting-up the system.

Method 1:

Clear the COMS data by setting the JCOMS1 ((2-3) closed)) as “ON”
status. All the CMOS data will be loaded as defaults setting.

Method 2:

Press the <Insert> key and Power button simultaneously, after that
keep-on pressing the <Insert> key until the power-on screen showed.
This action will boot-up the system according to FSB of the processor.

It’s strongly recommended to set CPU Vcore and clock in default
setting. If the CPU Vcore and clock are no t in default se tti ng, it may

cau se CP U or M/ B damage.
