CMOS RAM memory map下载

Below is a typical CMOS RAM memory map for an AT PC. Under a 128byte ISA compatible CMOS, 16 bytes (00h-0fh) is the real time clock, 32 bytes (10h-2Fh) is the ISA configuration data, 16 bytes (30h-3Fh) is the BIOS specific configuration data and 64 bytes (40h-7Fh) is the ESCD (Extended System Configuration Data).
