What Is a Hardware Compatibility List?

Hardware compatibility refers to the ability of multiple independent hardware devices to coordinate their work under the unified scheduling of the operating system to play a mutually exclusive role. If they fail to do this or even have IRQ conflicts, poor process generation, and different specifications, then hardware compatibility issues will arise.

A large part of computer failures are caused by hardware compatibility. For example, computer crashes, blue screens, black screens, various hardware failure sounds from motherboard speakers controlled by the BIOS chip, and various values displayed by the motherboard signal lights may be hardware compatibility failures. Faced with this kind of problem, many users are at a loss, and even some computer hardware maintenance companies have taken a detour, so the solution to this kind of problem is very important. The following section analyzes this point and introduces feasible methods.

Hardware compatibility refers to the ability of multiple independent hardware devices to coordinate their work under the unified scheduling of the operating system to play a mutually exclusive role. If they fail to do this or even have IRQ conflicts, poor process generation, and different specifications, then hardware compatibility issues will arise. For example, DDR2 memory and DDR3 memory sockets cannot be used universally. Some AM2 motherboards must pass

BIOS Hardware compatibility BIOS chip

The BIOS is a ROM chip integrated on the motherboard, which is responsible for initializing and testing the hardware in the computer system when the system is turned on to ensure that the system can operate normally. It is a basic input-output system and an important bridge between software layer and hardware layer. The BIOS provides a driver interface to set the status of system-related configurations. Differences in hardware devices lead to different parameter configurations. Reasonably setting the BIOS can not only eliminate some faults, but also give full play to the performance of the computer hardware and even extend the service life.

Hardware compatibility upgrade motherboard

BIOS requirements analysis Because the CMOS parameters can be set through the BIOS setup program, when the hardware has undergone major changes or upgrades, the original hardware environment can no longer support compatibility between devices. For example, our processors have changed. The original AM2 processor becomes an AM2 + processor or the frequency of the memory module is changed from 667MHZ to 800MHZ and the motherboard itself cannot achieve compatibility through other methods. When we need to overclock but the original motherboard function is lacking, then you can try this time Do this by updating the BIOS.

BIOS Method for updating BIOS with hardware compatibility

1) Finding a new version of the BIOS file Each motherboard manufacturer will regularly release updated BIOS versions to solve problems encountered in the actual use of the motherboard. These new BIOS are stored on the site for download in the form of files, then users You can find the corresponding manufacturer's site to download the latest BIOS file according to your motherboard model.

2) Select the appropriate flashing tool. There are generally two types of BIOS flashing tools: one is the flashing tool provided by the BIOS manufacturer, such as Awardflash, and the other is the motherboard flashing tool. Here we must analyze according to their specific circumstances. Generally, the flash program provided by the BIOS manufacturer can only be used to flash the BIOS produced by itself. Common ones are AWDBIOS and AMIBIOS. The following uses Awdbios as an example.

3) Preparations before upgrading the motherboard BIOS

A. First enter the BIOS setup interface. In the Advanced Bios Set-up function, set BIOSupdate to enabled so that new files can be written into the BIOS.

B. In the CMOS CHIPSET FEATURE SETUP function item, disable system bios cacheable and Video Bios Cacheable and Virus Warning (virus warning) and other functions to prevent restrictions on refresh. Finally save the CMOS settings and exit.

C. Because the current computer does not have a floppy drive, the method of making a floppy disk is not applicable. At this time, the new BIOS file (usually the extension is .bin) and the Awdflash.exe file are placed in the root directory of a partition on the hard disk Under the same folder. This makes it easy to find the files you want to use under DOS. Ready to work.

4) Update the BIOS file to directly find the system CD with pure DOS, or install a software with pure DOS directly in the system, restart the computer to enter the DOS system. If the latest BIOS file A.bin and Awdflash.exe are placed in the 123 folder in the root directory of the D partition, enter the DOS system and follow the steps to refresh: enter cd d: Enter to enter the D partition of the disk D: \ cd 123 Enter to enter the 123 folder of D partition; D: \ 123 Awdflash A.bin After entering, it shows: The path of the original BIOS file path is still stored in this folder, the file name is directly from Definition. For example, after the B.bin is saved, the new BIOS file A.bin prompting to use is directly pressed to start the update. The power cannot be cut off during the update process. The same can be achieved using the parameter command: D: \ 123 Awdflash A.bin / py / cd / cp / cc / r (py: flash memory, cd: clear DMI date, cp: clear PNP data, cc: clear CMOS after refresh Data, r: restart the system).

At this point, the refresh work is completed, and the motherboard BIOS is updated. At this time, the compatibility issue of the process specifications brought by the hardware update and upgrade can be solved.
