Computing power of brushing BIOS
Publish: 2021-05-06 08:01:14
1. There is such an operation. The so-called BIOS brushing is only applicable to some graphics cards, not all graphics cards. Some graphics cards are upgraded by manufacturers. For example, HD5750 and hd6750 increase the frequency of GPU, and a small amount of them increase the processor. But the core GPU is the same. At this time, you can brush BIOS to change 5750 into pseudo 6750 to improve the performance. This technique is similar to overclocking. But the success rate is not 100%.
2. BIOS is also the motherboard information. Simply put, for example, your graphics card is 9300. It's not very good to upgrade to 9800 motherboard compatibility. The official gave the BIOS refresh file. After brushing, it will be supported. Your computer's BIOS is factory. Don't brush it indiscriminately. Brand machines are the best ones to brush. You can't download the new files. The downloaded files are also fake. Once brushing, it will be broken. Now you need to check the invoice for maintenance
3. First understand, you do it, otherwise it is very dangerous
first, BIOS detailed explanation
for many novices, refreshing BIOS is still mysterious. And for some BIOS related knowledge, many people also know a little. Here, we will make a comprehensive understanding of BIOS
1. What is BIOS
BIOS is English & quot; Basic Input Output System" After literal translation, the Chinese name is & quot; Basic input output system & quot;. Its full name should be ROM-BIOS, which means read-only memory basic input-output system. In fact, it is a set of programs solidified to a ROM chip on the main board of the computer. It stores the most important basic input and output programs of the computer, system setting information, power on self check program and bootstrap program. Some people think that since BIOS is & quot; Program & quot;, Then it should belong to the software, and feel like word or excel. But many people don't think so, because it is different from general software, and it is closely related to hardware. Figuratively speaking, BIOS should be a bridge connecting software programs and hardware devices; Bridges;, Responsible for solving hardware immediate requirements. Whether the performance of a motherboard is superior or not depends largely on whether the management function of BIOS program is reasonable and advanced. The BIOS chip on the motherboard may be the only chip with a label on the motherboard. Generally, it is a 32 pin al in-line integrated circuit with & quot; printed on it; BIOS" word. Before 586, most BIOS chips were rewritable EPROM chips, and the label on them could protect the contents of BIOS (the contents of EPROM would be lost e to ultraviolet radiation) and could not be torn off. EEPROM (electrically erasable read-only ROM) is widely used in ROM BIOS after 586. EEPROM can be rewritten through jumper switch and system driver disk, which is convenient to upgrade BIOS. Common BIOS chips include award, AMI, Phoenix, Mr and so on. The manufacturer's mark can be seen on the chip< The main functions of bios are as follows:
the first is self-test and initialization program: after the computer power is turned on, the system will have a process of checking internal devices, which is completed by a program commonly known as post (power on self test), which is also a function of BIOS program. The complete self-test includes the test of CPU, 640K basic memory, 1m extended memory, ROM, motherboard, CMOS memory, serial and parallel port, display card, soft and hard disk subsystem and keyboard. In the process of self-test, if problems are found, the system will give a prompt message or whistle warning. If there is no problem, after completing the self-test, the BIOS will search for effective boot drivers such as soft and hard disk drives, CDROMs and network servers according to the boot order in the system CMOS settings, read in the operating system boot record, and then give the system control to the boot record. The boot record completes the system boot, and you can use your baby safely. The second is hardware interrupt processing: when the computer is turned on, BIOS will tell the interrupt number of CPU and other hardware devices. When you input a command to use a certain hardware, it will use the corresponding hardware to complete the command work according to the interrupt number. Finally, it will jump to the original state according to the interrupt number. Another is the program service request: from the definition of BIOS, we can know that it always deals with the input and output devices of the computer. It sends instructions through the most specific data port, sends or receives the data of various external devices, so as to realize the operation of software applications on hardware
3. BIOS and CMOS
many friends confuse the concepts of BIOS and CMOS. Here we talk about CMOS and its relationship with BIOS:
CMOS is & quot; Complementary Metal Oxide Semiconctor" Complementary metal oxide semiconctor memory is a kind of raw material used in the manufacture of integrated circuit chips on a large scale. But the exact meaning of CMOS here is a battery powered RAM chip which is used in most computers. The meaning of BIOS has been explained earlier. So, what is the relationship between CMOS and BIOS? CMOS is a memory chip, of course, belongs to hardware, its role is to have data storage function, but it can only play the role of storage, and can not set the data stored in it. To set the parameters in CMOS, it is necessary to go through a special setting program. Now most manufacturers have implemented the CMOS parameter setting program in the BIOS chip. When the computer turns on the power, press the special key to enter the setting program to set the system conveniently. That is to say, the system setup program in BIOS is the means to complete the setting of CMOS parameters, and CMOS ram is the place to store the set data, which has a great relationship with the system parameter setting of the computer. Because of this, there is? quot; CMOS settings & quot; And & quot; BIOS settings & quot; In fact, the accurate one should be & quot; Through the BIOS Setup program to set the CMOS parameters & quot;. BIOS and CMOS are both related and different; CMOS settings & quot; And & quot; BIOS settings & quot; It's just that you can simplify the setting process in two ways. In this sense, they both refer to a meeting
the CMOS memory chip can be powered by the battery of the main board. Even if the system is powered down, the stored data will not be lost. But what happens if the battery is removed? Good question! If the battery doesn't have power, or if there is a sudden contact problem, or if you take it off, the CMOS will lose all the data stored inside because of the power failure. But if this happens, it's not a big problem. You can replace the battery, or check the cause of poor contact. In a word, make sure that the CMOS has power. Restart the computer to enter the BIOS program and select & quot; in the main menu; LOAD BIOS DEFAULTS" Or & quot; LOAD SETUP DEFAULTS" Enter after, and then confirm the input & quot; Y" Just enter. You may have heard other players say that if you forget the power on password, you will discharge the CMOS. In fact, if you lose all the information including the password, you don't need to input the password when you power on, and then write the data again
4. The significance of upgrading BIOS
the reasons for upgrading bios are as follows:
(1) providing support for new hardware or technical specifications
with the rapid development of computer hardware technology, the motherboard can not correctly identify or provide support for some new hardware (such as k6-iii Celeron II CPU) or new technology (such as DMA100, DMA66, hard disk larger than 35gb), so it is necessary to upgrade BIOS to obtain support for new hardware or new technology
(2) solve the bug in the old version of BIOS< (3) solve the year 2000 problem. Many motherboards proced before 1997 have the year 2000 problem. Although some new motherboards have solved the year 2000 problem, they can't pass the Y2K test software. These problems can be solved by upgrading BIOS
5. What kind of BIOS can be upgraded
observe the BIOS chip on your motherboard (generally a 28 pin or 32 pin al in-line IC with the word BIOS on it). Most of the chips are award or AMI procts. Remove the label on the BIOS chip and you will see the number of the BIOS chip. For some motherboards, manufacturers use non upgradeable BIOS in order to save cost. Of course, you can also check the motherboard manual directly to see if there are instructions for upgrading the BIOS of the motherboard. However, even if there is no relevant explanation in the motherboard manual, you don't have to be discouraged. You can try it yourself. Because not all motherboards write this feature in the manual
here we need to clarify the following concepts, so that we can have a more comprehensive understanding of BIOS related knowledge. Of course, it can also be used to brag in front of friends, ha ha< (1) Prom: This is English & quot; Programmable read only memory & quot; It is a kind of memory chip, the content of which can not be modified once written, and the content will not disappear after the host is turned off. The difference between PROM and ROM is that prom is a blank chip without content when it leaves the factory, and the content of ROM has been written when it leaves the factory. To write content in PROM, you need a tool called Prom programmer, which is also called Prom burner; The process of writing content to prom is called burning< (2) EPROM: This is English; Erasable programmable read only memory & quot; It is a special Prom chip that can be erased by ultraviolet light. Once the content is erased, you can write new content again< (3) EEPROM: This is English; Electrically erasable programmable read only memory;, It can erase and write the contents by means of electricity. Like other prom, the contents will not disappear when the host is powered off
6. Sometimes when the system fails and cannot be displayed, we need to analyze the cause of the failure by interpreting the "language" of the PC speaker
therefore, it is very important to understand the "language" of the PC speaker. Let's take a look at the meaning analysis of our post ringing code

if not, adjust it slowly...
ordinary computers have decimal...
you can use K8 frequency menu software to see, Decimals are in 10 places

6. If you buy a vista system, you'd better not clear DMI, otherwise you may not be able to access the system or the software can't be used.
however, you'd better save the old version of BIOS before you brush BIOS to prevent the BIOS from being wiped dead.
remember not to power off or shut down in the middle of the process, Otherwise, you can only restore the data with the tool.

7. Well,
this kind of thing often happens. If the version is not correct, the power failure of the picture and the error in the refresh will lead to the refresh failure and unable to start, which is very troublesome.
now many motherboards have recovery measures after the refresh failure.
for example, the al BIOS BIOS recovery jumper asus's "brush not dead" technology
if not, the recovery is very troublesome ~
be careful

1. Make U disk and start disk
2. Download the latest BIOS from the main board's official website and unzip it to the root directory of the USB flash disk:
3. Insert the USB flash disk into the computer and restart it. Enter the BIOS and set the USB flash disk boot priority
4. Save the BIOS and exit. After restarting, you will enter the DOS interface, and enter dir to view the files in the U disk
5. Input backup to backup the BIOS and generate a bak.rom file in the U disk
6. Input update to start the BIOS brushing (the power must not be cut off ring the BIOS brushing process, otherwise the machine will fail and cannot be started)
prompt "program ended normally" or the cursor is not moving (pay attention to observe and wait) indicates that the BIOS refresh is successful. Finally, restart to see if you can enter the operating system normally
9. There's no harm in brushing BIOS
if it fails, it will be miserable. The computer itself will be scrapped, so there is a risk to swipe the BIOS. You must swipe the BIOS without power failure or without network connection. Any error will cost the computer....

10.
There are two ways to refresh the main board BIOS: one is to use floppy disk in DOS environment, and the other is to use special BIOS refresh software to refresh the main board BIOS in Windows operating system
risks and consequences: if the system is damaged, it cannot be started and needs to be returned to the factory (some motherboards use al BIOS, one of them is OK, and the other can ensure the normal startup of the user)

BIOS notes
first, when to upgrade
after upgrading the electronic procts, users find that they do not achieve the expected performance. For example, after replacing their own computers with more powerful CPU, blue screen and splash screen will appear.
Second, upgrade principle
Upgrade the BIOS of the motherboard. In principle, it must be 100% matched with the motherboard model before it can be refreshed. Otherwise, after the failure, the motherboard will not light up and the boot screen will be black, which will affect its service life. At the same time, there must be a corresponding burning program and a new version of BIOS data fileHot content
