The color bars will light on according to CPU operation temperature.

CPU Fan, Voltage and Temperature: representing CPU fan speed, CPU voltage and CPU temperature in Celsius and Fahrenheit degrees.

How You Adjust the Settings in BIOS

Apart from EzClock utility, the voltage and frequency values of CPU, PCI and memory can also be adjusted on BIOS page. By pressing “+”, “-“,“PgUp” or “PgDn” keys, you can adjust the frequency values of CPU Bus, PCI Bus and DRAM.

Also, the same keys help you adjust the voltage of CPU and DDR settings. Some values may change while you adjust the settings. You can press “F10” to save the changes you’ve made.

How Your Boot Screen Looks Like

After you finish setting BIOS, these setting values will be displayed on the boot screen like the shown picture here.

Every time you boot your system, both default and current settings will pop up on the screen. Your personal settings that had been adjusted earlier will be highlighted; thus, you can have clear idea how your system functions and monitor your system more easily.

Hyper Threading Technology

What is Hyper-Threading?

Hyper-Threadingtechnology is an innovative design from Intel that enablesmulti-threadedsoftware applications to process threads in parallel within each processor resulting in increased utilization of processor execution resources. As a result, an average improvement of ~40% in CPU resource utilization yields higher processing throughput.

How Hyper-ThreadingWorks

A form of simultaneous multi-threadingtechnology (SMT),Hyper-Threadingtechnology allows multiple threads of software applications to be run simultaneously on one processor by duplicating the architectural state on each processor while the same processor execution resources is shared. The figure below represents how aHyper-Threadingbased processor differentiates a traditional multiprocessor. Theleft-handconfiguration shows a traditional multiprocessor system with two physical processors. Each processor has its own independent execution resources and architectural state.

The right-handconfiguration represents an IntelHyper-Threadingtechnology based processor. You can see that the architectural state for each processor is duplicated, while the execution resources is shared.

For multiprocessor-capablesoftware applications, theHyper-Threadingbased processor is considered two separate logical processors on which the software applications can

run without modification. Also, each logical processor responds to interrupts independently. The first logical processor can track one software thread, while the second logical processor tracks another software thread simultaneously. Because the two threads share the same execution resources, the second thread can use resources that would be otherwise idle if only one thread was executing. This results in an increased utilization of the execution resources within each physical processor.

The figure below represents how Hyper-Threadingsaves time when it

works. With two logical processors available on every single physical processor, multi-threadedapplications can now take advantage ofthread-levelparallelism on each physical processor for additional performance. As software applications continue to be optimized to take greater advantage of processor parallelism,Hyper-Threadingtechnology provides an additional boost for newer capabilities and the growing needs of today’s users.

AOConfig Utility

AOpen always dedicated to provide users a much friendly computer environment. We now bring you a comprehensive system detection utility. AOConfig is a Windows based utility withuser-friendlyinterface that allows users to obtain information of the operation system

and hardware such as motherboard, CPU, memory, PCI devices and IDE devices. The powerful utility also displays the version of BIOS and firmware for your convenience of maintenance.

Moreover, AOConfig allows users to save information in *.BMP or *.TXT format which users may collect the system information in detail and send them to AOpen directly for technical support or for further diagnose of system problems.

1.The system page shows the detailed information of the motherboard, operating system, processor, and BIOS version.

2.The PCI device page shows the configurations of all PCI devices installed in your motherboard.

3.This page presents the IDE device information, such as serial number, manufacturer, firmware version, and capacity.

4.From this page, users can obtain the technical support information of AOpen. Moreover, detailed information could be saved in .bmp or .txt format.

NOTE:

AOConfig can be used under Windows 98SE/ME, NT4.0/2000, or Windows XP. Please also note that AOConfig can only be operated in a system equipped with an AOpen motherboard. Before running AOConfig, all applications must be closed.

Phoenix-AWARDBIOS

System parameters can be modified by going into BIOS Setup menu, this menu allows you to configure the system parameters and save the configuration into the 128 bytes CMOS area, (normally in the RTC chip or in the main chipset).

Phoenix-AwardBIOS™ installed in theFlash ROM of the motherboard is a custom version of an industry standard BIOS. The BIOS provides criticallow-levelsupport for standard devices such as hard disk drives, serial and parallel ports.

Most BIOS settings of AOpen i865 Family motherboards have been optimized by AOpen’s R&D engineering team. But, the default setting of BIOS still can’t fine-tunethe chipset controlling entire system. Therefore, the rest of this chapter intends to guide you the process of configuring your system setup.

To enter to BIOS setup menu, press <Del> when POST (Power-On Self Test) screen is shown on your monitor.

Note: Because the BIOS code is the most often changed part of the motherboard design, the BIOS information contained in this manual may be different with actual BIOS that come with your motherboard.

BIOS Upgrade under Windows environmen

With outstanding R&D ability of AOpen, we now bring you a whole new BIOS Flash wizard ----

EzWinFlash. With an eye to users convenience, EzWinFlash combines the BIOS binary code and flash module together, so the only thing you have to do is just clicking on the utility you downloaded from web and let it helps you complete the flash process automatically. EzWinFlash detects your motherboard and checks

the BIOS version cleverly to prevent your system from any possible failure. Moreover, EzWinFlash has been taken into consideration to go with any windows platform you might be using, no matter if you’re using Windows 95/98, 98SE/ME, NT4.0/2000, or Windows XP.

In the meanwhile, in order to provide a much more user-friendlyoperating environment, AOpen EzWinFlash is natively designed to havemulti-languagefunction to provide easier way for users’ usage in changing BIOS setting.

Caution: By updating your motherboard, you are taking a risk of BIOS flash failure. If your motherboard is working stable, and there are no major bugs that had been fixed by a latter BIOS revision, we recommend that you DO NOT try to upgrade your BIOS. If you intent on upgrading, PLEASE BE SURE to get the right BIOS revision for the right motherboard model to avoid any possibility failure.
