CMOS是互补金属氧化物半导体的缩写。其本意是指制造大规模集成电路芯片用的一种技术或用这种技术制造出来的芯片。在这里通常是指微机主板上的一块可读写的RAM芯片。它存储了微机系统的实时钟信息和硬件配置信息等,共计128个字节。系统在加电引导机器时,要读取CMOS信息,用来初始化机器各个部 CMOS is an abbreviation of complementary metal oxide semiconductor. The intention is to create a technology for manufacturing LSI chips or a chip manufactured using this technology. Here usually refers to a computer motherboard readable and writable RAM chip. It stores the computer system’s real-time clock information and hardware configuration information, a total of 128 bytes. The system is powered on to boot the machine, to read CMOS information, used to initialize the various parts of the machine
