Chapter 3. BIOS SETUP


25

Chapter 3 BIOS SETUP AMI BIOS Flash BIOS functions as a bridge connecting hardware and operating system. Hardware and

software are upgrading all the time, so when your system goes wrong, for example, your

system can not support the newest CPU, you need to upgrade BIOS to keep up with the latest

technology.

AFUDOS.EXE is the FLASH IC program for BIOS to upgrade, which needs to be run in DOS

mode.

Pls use a boot disk to load DOS, then run AFUDOS.EXE to upgrade BIOS（ for example: write

XXXX.ROM into FLASH IC ）

Order Format:

A:\ Afudos XXXX.rom / P /B /C /N /X

If you need to add other parameters, pls add <space>/? after the order format

Remark:

1. BIOS upgrading is only executed when your system goes wrong.

2. Please use the upgrading program in the CD-ROM provided by us or download the latest

version of the upgrading program on-line

3. Please do not power off or reboot the system when upgrading, otherwise, the BIOS maybe

be damaged or system may not be able to boot again.

4．Please backup your BIOS before upgrading

AMI BIOS Description When the computer is power on, BIOS will conduct self-diagnosis to its hardware on

motherboard and configure hardware parameter, finally the operating system will take control.

BIOS is the communication bridge between hardware and O/S. Correct configuration of BIOS

is critical for maintaining system stability and its optimized performance.

BIOS Setup After finishing the self-diagnosis, following message will show on the screen:

DEL->SETUP, pls press DEL，then system will enter BIOS setup interface automatically atfer

doing the IDE detection:

1. Power on or reboot the computer, self-detection information will show:


26

2. When message shows as "Press <DEL> to enter setup"，pls press <DEL>, then enter into

BIOS SETUP Program.

3. Use the “←↑→↓”to choose the option which your want to modify, press <Enter> and then

the sub-menu.will show.

4. Use the “←↑→↓”and <Enter> to modify the value; press”Enter” to modify BIOS options

that you choose

5. At any time, press<Esc> can go back to the father-menu.

3.2.1 CPU Configuration

Read Only option contains the detailed information of your CPU, including CPU manufacturer,

CPU Model, frequency, L1 cache, L2cache, etc.

Hardware Prefetcher

The CPU will guess what data the current program will require next and fetch it from the cache

before it's needed. If it guesses correctly, this saves processing cycles. If the CPU guesses

wrong, it wastes processing cycles while it recovers and grabs the correct data. Intel has made

Sandy Bridge pretty good at guessing, so leave it enabled.

Adjacent Cache Line Prefetch

[Enabled]: When the CPU retrieves data from the cache, it not only grabs the required data but

also the next area. For a lot of programs, this will once again save processing cycles.

Max CPUID Value Limit

Please set this item as [Enabled] if the system OS doesn’t support the extended CPUID

Intel（R）Virtualization Tech

Intel virtualization technology enables to run multiple O/S of the same kind or different kind by

using the same physical platform so as to realize the management and allocation of computer

resources, maxmizing the resource utilization，

Execute-Disable Bit Capability

Execute Disable Bit (EDB) is a hardware-based security feature that introduced to its new

generation CPU by Intel, which can help reduce system exposure to viruses and malicious

code. EDB allows the processor to classify areas in memory where application code can or

cannot execute. To use Execute Disable Bit you must have Windows XP SP2 operating system

to support this function.

Appendix 2. Glossary

ACPI

Advanced Configuration and Power Management. ACPI specifications allow O/S to control most

power of the computer and its add-ons

Windows 98/98SE，Windows 2000 and Windows ME all support this function, which enable users to

manage the system power flexibly.

BIOS

Basic input/output system. It’s a kind of software including all in/out control code interface in PC. It will

do hardware testing while system is booting, then system runs, it provides an interface between OS

and hardware. BIOS is stored in a ROM chip.

BUS

In a computer system, it is the channel among different parts for exchanging data; it’s also a group of

hardware lines. BUS here refers to part lines inside CPU and main components of memory.

Chipset

Integrated chips for executing one or more functions. Here “Chipset” refers to system level chipset

structured by Southbridge & Northbridge; it determines motherboard’s structure and main functions.

CMOS

Complementary Metal-Oxide Semiconductor, a widely used semiconductor with the characteristic of

high speed but low-power-consumption. CMOS here refers to part of reserved space in on-board

CMOS RAM, for saving date, time, system information and system parameter etc.

COM

Computer-Output Microfilmer. A universal serial communication interface, usually adopts normative

DB9 connector.

DIMM

Dual-Inline-Memory-Module. It’s a small circuit board with memory chipset, providing 64bit RAM bus


67

width.

DRAM

Dynamic Random Access Memorizer. It’s a normal type of universal memory often with a transistor

and a capacitance to store 1 bit. With the development of the technology, more and more types of

ORAM with various specifications exist in computer application, such as SDRAM, DDR SDRAM and

RDRAM

I2C

I2C（Inter－Integrated Circuit）, generically referred to as two-wire interface, is a multi-master serial

single-ended computer bus invented by Philips that is used to attach low-speed peripherals to a

motherboard, embedded system, cellphone, or other electronic device.

LAN

Network interface. Network grouped by correlative computers in a small area, generally in a company

or a building. Local area network is generally buildup by sever, workstation, some communication

links. Terminals can access data and devices anywhere through cables so that many users can share

costly device and resource.

LED

Light-Emitting Diode. a semiconductor device that shines when power supply is connected, often

used to denote info directly by light, for example, to denote power on or HDD work normally.

PnP

Plug-and-Play. It is a specification that allows PC to configure its external devices automatically and

can work independently without the manual operation by its user . To achieve this function, its BIOS

should be able to support PnP and a PnP expansion card.

POST

Self-test when power on. While booting, BIOS will do an uninterrupted testing to the system, including

RAM, keyboard, hard disk driver etc. to check if all the components are in normal situation and work

well.

PS/2


68

A keyboard & mouse connective interface specification developed by IBM.PS/2 is a DIN interface with

only 6PIN; it also can connect other devices, like modem.

USB

It’s Universal Serial Bus for short. A hardware interface adapts to low speed external devices, and is

always used to connect keyboard, mouse etc. One PC can connect maximum 127 USB devices,

providing 12Mbit/s transmit bandwidth；USB supports hot swap and multi- data stream, namely, you

can plug USB devices while system is running, system can auto-detect and makes it work
