First, the BIOS password

Unlike other programs, the BIOS is stored in the BIOS chip, not on the disk. Since it is part of the motherboard, it is sometimes called a name that is different from software and hardware. "Firmware" (Firmware), which is mainly used to store self-diagnostic test programs (POST programs), system bootloaders, system setup programs, and I/O drivers and interrupt service routines for major I/O devices.
If you don't want others to use your own computer, you can set the password function of the BIOS to add a “lock” to the computer. What should I do if I forget the BIOS password? Don't worry, the following tips can help you.
