It provides the lowest level and most direct hardware control for the computer. The BIOS program is generally stored in the motherboard ROM (read-only memory chip). Even after shutting down or losing power, the program will not be lost. There are BIOS programs in many hardware of the computer. The most common ones are: the motherboard (also called system BIOS), display card and some other devices (such as IDE controller, SCSI card or network card, etc.); however, the computer startup process is carried out under the control of the system BIOS.

[0042] Performing FPGA signal detection on the repaired BIOS firmware content and determining whether the signal is correct;
