CMOS is short for the half guide of complementary metal oxides. It is a technology used to manufacture large-scale integrated circuit chips or a chip manufactured using this technology. In fact, it refers to a read-write storage chip on the motherboard. It stores the clock information and hardware configuration information of the microcomputer system, totaling 128 bytes. When the system powers up the boot, it needs to read the CMOS information to initialize the status of each part of the machine
The BIOS has self-test and bootstrap program, after the machine power up, the CPU automatically calls the program in the BIOS, the system hardware initialization and hardware failure check, including the various boards. After checking, the BIOS transfers control to the hard drive master boot record (MBR), the BIOS tran
