2020 is a heartbreaking time and enough time for the world to remember. When we enter the year 2020 with great joy, a disaster and a worldwide disaster will come unexpectedly
the new type of coronary pneumonia, which broke out in January, has not been over for more than half a year. Of course, China has always been on the front line of the fight against the epidemic and has made great efforts to prevent and control the epidemic. In February, March, April and may, how painful the Chinese people were, and how strong the Chinese doctors and nurses were{ RRRRR}
we hope we can return to normal life, we hope we can take off the mask, walk on the street confidently and say hello to everyone

If you want to say which word is the most topical in 2020? I believe that if the new crown is ranked second, there is really no word to rank first. Since the outbreak, it has been affecting the hearts of people all over the world. Especially when it broke out for the first time in Wuhan, China, everyone's nervousness is still like yesterday. Although China finally overcame the epidemic in Wuhan through the unremitting efforts of the people of the whole country. So that most city can resume work and resume proction, but throughout the world, many countries are still in the mire of COVID-19. And novel coronavirus pneumonia deaths have exceeded two million worldwide. The number of novel coronavirus pneumonia cases is also increasing. So when can the new crown be completely eliminated
3. BIOS is basic
input / output
system (abbreviation of basic input / output system). BIOS is a set of computer programs for setting hardware, which is stored in an EPROM or EEPROM chip on the motherboard. It contains the important information of the system and the setup program for setting system parameters BIOS
setup program. BIOS is the most basic and important program in the computer. It will put this program in a memory (chip) that does not need power supply. BIOS is a requirement between hardware and software program, and it will execute interface or converter according to the operation requirements of software to hardware, which plays a very important role in the computer system

4. Mi BIOS, award BIOS and Phoenix BIOS. Among them, award and Phoenix have been merged, and their technologies have been integrated with each other. From the functional point of view, BIOS is divided into three parts:
self test and initialization program
hardware interrupt processing
program service request
from the functional point of view, BIOS is divided into three parts:
self check and initialization. This part is responsible for starting the computer, and specifically has three parts:
the first part is used to detect the hardware part when the computer is just connected to the power supply, also known as power on self test (post). The function is to check whether the computer is in good condition, Generally, the complete post self-test will include the test of CPU, 640K basic memory, 1m or more expanded memory, ROM, motherboard, CMOS memory, serial and parallel port, display card, soft and hard disk subsystem and keyboard. Once any problem is found in the self-test, the system will give a prompt or sound a warning. If any error is found in the self-test, it will be dealt with in two ways: for serious fault (fatal fault), it will be shut down. At this time, because various initialization operations have not been completed, no prompt or signal can be given; For non serious fault, it will give a prompt or sound alarm signal, waiting for the user to deal with
the second part is initialization, which includes creating interrupt vectors, setting registers, initializing and detecting some external devices, etc. the most important part is BIOS settings, mainly for some parameters of hardware settings. When the computer starts up, these parameters will be read and compared with the actual hardware settings. If they are not consistent, the system startup will be affected
the third part is bootloader, which is used to boot DOS or other operating systems. BIOS first reads the boot record from the beginning sector of the floppy disk or hard disk. If the boot record is not found, it will show that there is no boot device on the display. If the boot record is found, the control of the computer will be transferred to the boot record, and the operating system will be loaded into the computer by the boot record. After the computer starts successfully, this part of the BIOS task is completed
program service handler service handler mainly serves applications and operating systems. These services are mainly related to input / output devices, such as reading disks, outputting files to printers, etc. In order to complete these operations, BIOS must directly deal with the I / O devices of the computer. It sends commands through the port, transmits data to various external devices and receives data from them, so that the program can be separated from the specific hardware operation
hardware interrupt processing hardware interrupt processing deals with the needs of PC hardware respectively. The service function of BIOS is realized by calling interrupt service program. These services are divided into many groups, and each group has a special interrupt. For example, for video service, the interrupt number is 10h; Screen printing, interrupt number 05H; Disk and serial port service, interrupt 14h, etc. Each group is subdivided into different service numbers according to specific functions. What peripherals an application program needs to use and what operations it needs to perform are explained by corresponding instructions in the program without direct control 2 (3) although the two parts are two independent contents, they are closely related in use. These two parts are software and hardware services, which are combined to make the computer system run normally. In addition, it should be noted that improper BIOS settings will directly damage the computer's hardware, or even burn the motherboard. It is recommended that those unfamiliar with BIOS settings be careful to modify them. Record the settings. Users can set BIOS to change various settings, such as the memory size of the onboard graphics card. All the operating systems in the user's hands are transferred to the boot sector by BIOS, and then transferred to the operating system of each partition activation response by boot sector.

9. BIOS, or ROM-BIOS, is the abbreviation of the basic input / output system of read-only memory. It is actually a set of programs solidified into the computer, providing the lowest and most direct hardware control for the computer. To be exact, BIOS is a "converter" or interface between hardware and software program (although it is only a program itself), which is responsible for solving the immediate needs of hardware and executing according to the operation requirements of software to hardware< According to the function, BIOS can be divided into three parts:
