How to turn off the computer startup BIOS self-lifting information?

1. Press the delete key to enter the BIOS and enter the advanced configuration page (ADvanced Setup Page), find the Quick Boot item and set it to Enabled. It will skip the self-test.

2. Press the del key to enter the BIOS, enter the Advanced Setup Page, find the Quick Boot item, and set it to Enabled. Press F10 to enter to save and then turn on to skip the self-test and directly enter the system.

3. Method 1: Set BIOS Keep pressing Del to boot into the advanced BIOS setting page and enter the advanced BIOS function or BIOS function settings. Find "Quick Self-test Power", set it to "Enable", and press F10 to save and exit. In The Future, Press Esc To Skip The Test Directly.

4. The specific steps for turning on and turning off the ASUS motherboard self-test are as follows: First, go back to the desktop and right-click the win key in the lower left corner. Select Run in the start right-click menu. Enter regedit in the run and click OK to call up the registry.

There are four important programs on the BIOS, two of which are: power-on self-check program, system startup self-lifting...

The main programs stored in the BIOS include: self-diagnostic program, CMOS setting program, system automatic loading program and main I/O driver and interrupt service) . The BIOS program first checks whether the computer hardware can meet the basic requirements of operation.Piece, this is called "Power-On Self-Test", abbreviated as POST.

Includes: power-on self-check, interrupt routine, system settings, self-check program. Interrupt routine The interrupt routine in the BIOS is the BIOS interrupt service program. It is a programmable interface between the software and hardware of the microcomputer system, which is used to connect the functions of the program software and the hardware of the microcomputer.

It is not that rom contains four programs, but eprom contains four programs, namely BIOS interrupt service program, BIOS system setting program, POST power-on self-check program, and BIOS system startup self-lifting program.

In fact, it is a group of programs solidified on a ROM chip on the motherboard of the computer. ItIt saves the most important basic input and output programs of the computer, system setting information, power-on self-check program and system start-up self-lifting program. Its main function is to provide the lowest and most direct hardware settings and controls for the computer.

The system starts the BIOS, that is, the Basic Input-Output System of the microcomputer, is a ROM chip integrated into the motherboard, which saves the most important basic input/output programs and systems of the microcomputer system. Information settings, power-on self-check program and system start-up self-lifting program.

System start-up BIOS, that is, Basic Input-Output System of microcomputer, is a ROM chip integrated into the motherboard, which contains the most important basic input/output program of the microcomputer system, system information settings, power-on self-test program and system boot self-lifting program.

What does it mean to start the self-lifting program in the computer system?

The word bootstrapping comes from the idea that people stand up by their own "bootstrapping" mechanism.

Run. After the self-test is successful, load the boot program on the disk into the memory and let it run to load into the DOS system.

bootstrap computer devices use hardware-loaded programs to initialize enough software to find and load a fully functional operating system.

The computer self-checking process is a complex process, roughly as follows: First, after the computer is powered up, the host power supply immediately generates a "Power Good" low potential signal, which outputs a valid RESET signal through the clock generation (driver), so that the CPU enters the reset state. , and force the system to enter the ROM-BIOS program area.

System boot BIOS, that is, the Basic Input-Output System of the microcomputer, is a ROM chip integrated on the motherboard, which stores the most important basic input/output program of the microcomputer system. Unified information settings, power-on self-check program and system start-up self-lifting program.

The function of the self-lifting program saved in the BIOS is to load the operating system

1, run. After the self-test is successful, load the boot program on the disk into the memory and let it run to load into the DOS system.

2. The BIOS chip (ROM) on the motherboard stores the "self-loading program" and is responsible for booting the installation operating system (power-on).Logically, the main memory is composed of auxiliary memory RAM + ROM, and the connection method of the two is often unified addressing bit expansion is to connect the address end, chip selection end and read and write control end of multiple memory chips in parallel, and the data end is derived separately.

3. The last part is the dredging program, and the function is to guide DOS or other operating systems.

4. CMOS chips only have the function of saving data, and the modification of various parameters in CMOS should be realized through the BIOS setting program. In-depth understanding of BIOS BIOS basic concept BIOS (Basic Input / Output System) - a basic input and output system, usually solidified in read-only memory (ROM), so it is also known as ROM-BIOS.

Which hero can help explain what system self-lifting is

Its full name should be ROM-BIOS, which means read-only memory basic input and output system. In fact, it is a set of programs that are solidified on a ROM chip on the motherboard of the computer. It saves the most important basic input and output programs of the computer, system setting information, power-on self-check program and system start-up self-lifting program.

Let's talk about the circuit you gave. In the figure, the U64 output Y pin is a periodic square wave signal. The high level is 5V and the low level is 0V. The D3C710 is composed of a self-lifting circuit from 5V to 10V. The 1 pin of D32 is 5V. After self-lifting, the 2 pins of D32 (voltage on capacitor C722) become 10V.

CMOS (which originally refers to complementary metal oxide semiconductors - a raw material used in the manufacture of integrated circuit chips on a large scale) is a readable and writable RAM chip on the motherboard of a microcomputer, which is used to save the hardware configuration of the current system and the user's settings for certain parameters.

... Operating system, boot program, self-loading program, the execution order of these four is

1. The order of the computer power-up start-up process: power-up self-check program, self-lifting installation program, boot program, operating system.

2. Select A, POST program → CMOS setting program → system self-lifting program → boot program "reset"It is to reset the CPU by hardware control, force the suspension of any work tasks, clear the data of the register and all units of RAM in the CPU, carry out another power-on self-test, and then boot the operating system.

3. Step 1: When we press the power switch, the power supply begins to supply power to the motherboard and other devices. At this time, the voltage is not very stable. The control chipset on the motherboard will send and maintain a RESET signal to the CPU, so that the CPU will automatically return to the initial state. But the CPU will not execute instructions immediately at this moment.

4. Select "Automatic Installation", and the system will automatically identify the driver and complete the installation. ( AUDIO is the sound card, VGA is the graphics card, and SM is the main board. You need to install the motherboard driver first. If there is no SM item, it means that you don't need to install it).Restart the computer after installing all the drivers. So far, the driver installation is completed.
