After careful consideration, I still had a bit of confusion when I learned how to start the Windows system: the CPU reset signal is revoked, and the CPU will go from f000: the fff0 address (that is, 64 KB of the top address of 1 mb ram) is executed. This location is actually a jump command, which is directly directed to the BIOS address for execution.
Why am I still confused about this? When I am confused, in my mind, the CPU can only deal with Ram di
I browsed a lot of forums, vision, bios home, our friends will include our 51nb forum, from these forums, a large number of excellent posts to benefit, but also found that some of the posted more for the topic of earning replies, this kind of topic will usually astray not shallow, For example, the current Win7 hard brush 2.1 Implementation of OEM Activation is a lot of people sought after the topic, many of the steps of the tutorial is not clear cause
first, what is the BIOS
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.

With the development of computer technology, a variety of external equipment is also constantly developing, users can according to their own requirements, choose different hardware configuration, and the composition of their own hardware system. At this time, the user's hardware equipment information records, so that when the system starts to be able to specify the hardware system configuration and user settings for hardware parameters to ensure that the normal operation of t
The BIOS is the most basic and important system software, which is stored in a special chip, which plays a key role in the process of computer startup and operation. The BIOS setup tool allows you to configure your computer's hardware environment as needed to prepare for system initialization.The BIOS is the short name of the basic input output system. is the mos

From the 386 era, the address bus of the CPU is 32-bit and can access the 4 GB address code. From Pentium II to Pentium IV, we can theoret
The first thing you need to remind users is that if you feel the hardware knowledge, especially the BIOS is slightly missing, or do not imitate the operation of this article, in the brush BIOS upgrade process to do the most possible not to make mistakes. Although most gigabyte and ASUS motherboards currently on the market have a way to automatically restore the BIOS
The BIOS is a set of hardware-installed computer programs that are stored in a single ROM chip on the motherboard. Unlike CMOS, CMOS is a read-write RAM chip on the motherboard of a computer, which is used to save the hardware configuration of the current system and the user's settings for certain parameters. The CMOS chip is powered by a rechargeable battery on the motherboard, and the parameters are not lost even if the system is powered off. CMOS c
All want to make a U disk Boot tool installed system people should know that when the computer starts, only the U disk set as the first boot entry will boot into the PE environment from the U disk. Thus can in the PE environment to the computer hard disk repartition or in the PE environment Ghost installs the system. So how do you set the USB disk as the first startup item for your computer? This is mainly related to the BIOS board, and the domestic m
ASUS Notebooks now use the Aptio solution for Ami, based on EFI (extensible firmware Interface), UEFI (Unified EFI) and Intel platform to improve the specification framework, overall, EFI can allow the computer to jump out of the traditional BIOS 128Kbytes limit, support more equipment and a larger hard disk, the use of more flexible, but the content of this post is to help your friends "how to do" rather than "do so according to a certain theory", So
First, press the Delelte key during power-on to enter the direct BIOS setup program. Of course, note that different types of machines enter the BIOS setup program keys are different, and some on the screen to give hints, and some do not give a hint. Here are some common ways to enter the BIOS setup program. The following figure:

The BIOS (Basic input/output system) is a set of programs that are solidified in a computer's CMOS RAM chip to provide the first, most direct hardware control for the computer. There are two main types of BIOS: the award BIOS and the AMI BIOS. The correct setting of the BIOS
The computer BIOS is divided into three broad categories, namely the Phoenix BIOS, the award BIOS, and the AMI BIOS. To enter the BIOS interface, press and release the Del or F1 keys repeatedly when you turn on the boot. The BIOS
To allow the computer to boot from the U disk, you need to set up the BIOS in advance, and set the first boot of the sequence to the USB device.
