Boot by f1 solution introduction

Recently, I have encountered several computers and always found that I want to press F1 when I boot, and the way they appear is different. Sometimes when I use the computer, I will press the F1 button. Most of my friends may just follow the computer system's press f1 to continue. The prompt of pressing, may not pay attention to the reason, here is a brief introduction to the reasons for this situation, you can determine your computer based on the actual situation. Combine the online information and your own experience here to summarize the solution of pressing F1, I hope to help you in daily computer use! As we all know, the computer is pressed to press F1, which means that the computer can not successfully pass all the commands detected on the motherboard during the detection process. As for the command, we will not dare to control it! We only need to know that when the boot computer detects that the command is incorrect, it is necessary to press F1! Below I briefly talk about the general process of computer boot: when we press the boot button, the computer's boot circuit will give the motherboard a message, the system bios will follow a certain step to detect the availability of the major hardware, at this time the CPU also Did not start working! First, the motherboard system bios will read all the bios information from the smos chip. When the system bios issues a command to read the information, the motherboard bios chip will detect the major hardware of the motherboard, and then return to the system bios, through the memory north and south bridge. The chip exchanges information with the CPU. At this time, the display of the computer starts to be displayed, and the CPU is ready for work! Of course, our usual computer boot process is much more complicated than what is said here, here is a brief description! From the above information, the hardware and accessories on the motherboard are detected by the bios chip, so the booting we usually encounter is basically related to the system bios according to F1, and the system bios data is stored in the smos, smos is in A battery-powered chip that stores data on the motherboard (we call it a clock circuit)! First: the software caused by the so-called software, nothing more than the system bios data is not set, so smos detection can not pass the specific phenomenon as follows: 1bios floppy drive did not turn off the boot continuously press the del button (some are pressed F2 F8 F10, to see the motherboard Set), enter bios (this motherboard presses the del key)
