As you know, the BIOS setup method for the desktop board BIOS and notebook is not exactly the same, and the motherboard BIOS setup is relatively simple, but the problem can be solved quickly. However, if there is a problem with the notebook BIOS, it is not a good solution. This article will introduce the functional pri

The BIOS is an EPROM or EEPROM chip on the motherboard, which contains important information about the system and setup procedures for setting system parameters (BIOS setup program);CMOS is a read-write RAM chip on the motherboard, which is equipped with the specific parameters of the system configuration, the contents of which can be read and written by the Setup program.The CMOS RAM chip is powered by the

Some users will be prompted to have devices that are not working properly when they use the hardware information of the system. This can occur because the device is disabled in the BIOS and needs to be opened in the BIOS.In addition, some users need to disable some of the devices not commonly used, such as optical drives, to achieve energy-saving purposes. The following is an example of an optical drive that explains how to disable or enable a device

Under normal circumstances, the user has little access to the BIOS, so the BIOS settings are very unfamiliar, the following brings you to understand the bios of those common settings, whether in the installation system, or in the resolution of computer failures, are very useful. First, what is the BIOS The complete

In Linux, refresh the motherboard BIOS-general Linux technology-Linux technology and application information. The following is a detailed description. After all, hardware vendors do not provide BIOS write tools for Linux, or they do not need to bypass FreeDOS. Flushing the BIOS of the motherboard not only fixes some existing problems, but also supports updatin

Currently, the popular motherboard bios in the market is mainly award bios, AMI BIOS, Phoenix bios of these three types. The type of BIOS for the motherboard can be judged from the specification, motherboard identification, or computer startup screen. Although from the moth

Let's introduce the award BIOS settings, in fact, award BIOS and the AMI bios inside a lot of things are the same, can be said to be basically the same, although some names are different, but the actual effect is the same. I have already learned some basic BIOS basics, and settings, so in this article I will give a mor

The ThinkPad notebook brushes the BIOS tutorial currently has two ways: CD-ROM boot refresh BIOS method Second, the operating system to refresh the BIOS method Tips: There is a significant risk of a BIOS refresh upgrade, please proceed with caution. Before refreshing, the battery must be full power, the AC adapter

Activation Process of the BIOS From the time you press the power source on the master machine to the time when you enter the operating system, the BIOS stored in the mirror EEPROM on the host Board (compact and programmable unique memory) will start to perform the following operations:1. Initialization: When the power supply is turned on, the CPU will reset itself to the initial bandwidth for running.

The BIOS is the English "basic Input Output system" abbreviation, after literal translation after the Chinese name is "the basic input to export systems". Its full name should be Rom-bios, which means read-only memory basic input and output system. In fact, it is a group of curing to the computer motherboard on the previous ROM chip program, it holds the computer's most important basic input and output of t

Security researcher Jonathan Brossard created a conceptual verification hardware backdoor called Rakshasa, which is said to be able to replace the computer's BIOS (Basic Input/Output System) and endanger the operating system at startup, but it does not leave any trace on the hard disk.Brossard is the CEO and security research engineer of Toucan systems, a French security company. He demonstrated how the malware works at the Defcon hacking conference o

This version provides the ability to verify the entire BIOS file when the Award bios file is opened. When the entire BIOS file verification fails, a dialog box is provided to fix the BIOS file verification, the system prompts whether to fix the BIOS file. If the

The SWI module manages software interruption services. These interrupt service programs are closely related to Hwi hardware interrupt service programs. Generally, most of the daily processing functions are placed in these software interrupt service programs for management and operation. I. Overview of the SWI Module In the DSP/BIOS kernel, the threads managed and run by the system are divided into four levels: hardware interrupt service program, softw

First of all, what is Bios,bios's Chinese meaning is "basic input and output system", the main function is to provide the lowest level of the computer, the most direct hardware settings and control. So after assembling the computer, set not set all can, small suggestions, set up a bit better, the following to teach you how to set up the BIOS.After the computer assembly, the specific parameters to set, but also to see the computer Configuration and mot

Now many users in the configuration of a new computer, usually in the new computer at the same time installed two hard disk, that is, the mechanical hard disk +SSD solid-state drive, to store the corresponding data, and secondly can increase the speed of the system, set up our two hard drives are installed in separate systems, So long need to set the boot sequence in the BIOS to select the system to start the default letter, but many users do not know

When you enter the BIOS settings, you cannot modify the settings of the data, there are many reasons for this situation, different ways of handling. 1. When setting the BIOS, the different version of the operation method also does not make sense, and some BIOS version settings similar to the operation in Windows, you can press ENTER.
