What Are the Basics of Motherboard Identification?

At present, the main BIOS on the market are AMI BIOS, Award BIOS, and Phoenix BIOS. Among them, Award and Phoenix have been merged, and the technologies of the two have also merged with each other.

Motherboard knowledge

1. What do the English letters on the motherboard represent

2. Principle of computer startup

3. Motherboard

From a functional perspective,

This part is responsible for starting the computer. There are three specific parts. The first part is used to detect the hardware part when the computer is powered on. It is also called Power On Self Test (POST). Its function is to check the computer. Good or not, usually complete

These two parts are two separate contents, but they are closely related in use.

Program service handlers mainly serve applications and operating systems. These services are mainly related to

Because CMOS and BIOS are closely related to the computer system settings, there is only a statement about CMOS settings and BIOS settings. Because of this, beginners often confuse the two. CMOS RAM is where the system parameters are stored, while in the BIOS

The BIOS chip uses Flash ROM, which can be upgraded by a specific writing program. There are two main purposes to upgrade the BIOS:

The most direct benefit of upgrading the BIOS for free with new features is that you can get many new features without spending money, such as support for new frequencies and new types of CPUs. For example, some old motherboards previously supported the Tualatin core Pentium III and Celeron by upgrading the BIOS. Some current motherboards can support the latest Prescott core Pentium 4E CPU by upgrading the BIOS; break the capacity limit and directly use large-capacity hard disks; obtain new boot methods; enable previously blocked features, such as Intel s Hyper-Threading Technology, VIA's memory interleaving technology, etc .; identify other new hardware, etc.

Solve the bugs in the old BIOS. Since the BIOS is also a program, there must be bugs, and the hardware technology develops with each passing day. As the market competition intensifies, the cycle of launching products by motherboard manufacturers is getting shorter and shorter. Wishful, and these BUGs often cause inexplicable failures, such as restarting for no reason, often crashing, low system performance, equipment conflicts, hardware devices "lost" for no reason, and so on. After user feedback and the manufacturer's own discovery, responsible manufacturers will promptly launch a new version of the BIOS to fix these known bugs, so as to solve those inexplicable failures.

Because BIOS upgrades are dangerous, motherboard manufacturers have developed many BIOS-specific technologies to meet the actual needs of their products and users. For example, the BIOS update includes the famous Gigabyte @BIOS Writer, which supports Gigabyte motherboards to automatically find a new version of the BIOS online and automatically download and refresh the BIOS. Dangerous, and Gigabyte @BIOS also supports many non-Gigabyte motherboards to backup and refresh the BIOS under Windows; other similar BIOS features include ASUS Live Update, Abit's Abit Flash Menu, QDI's Update Easy, and MSI's Live Update 3, etc. In addition to the motherboard BIOS of MSI, MSI's graphics card BIOS and optical storage device's Firmware can also be automatically refreshed online. It is a very powerful MSI product dedicated tool. In addition, Intel's original motherboard's Express BIOS Update technology also supports flashing the BIOS under windows, and this technology is an executable program that combines the BIOS file and the refresh program, which is very suitable for beginners. Gigabyte's dual BIOS technology, QDI's King Kong lock technology, Intel's original motherboard's Recovery BIOS technology, etc. are used to prevent BIOS corruption and flash failure.

In addition to the manufacturer's new BIOS, in fact, we can also modify the BIOS to a certain extent to obtain certain new features, such as changing the ENERGY STAR logo, changing the full-screen startup screen, and obtaining certain features of certain brand motherboards (such as Add Jetway Recovery Wizard module for non-Jetway motherboards), add graphics card BIOS module to rescue BIOS damaged graphics cards, turn on chipset functions blocked by motherboard manufacturers, and even support new CPU types, directly supporting large-capacity hard drives without DM Software like that. However, these all need to be very familiar with the BIOS and have some hands-on ability and experience before they can do it.
