Is CMOSRAM is a part on mother board or part of RAM


In bootseqence of linux, the first step is check the CMOSRAM(size 64bytes) setup for custmor setting. So i am just confused wether CMOSRAM is a part of motherboard or is a part of RAM itself. If am wrong some where please correct me

CMOS (BIOS) is stored on an eeprom chip on the mb and is what the computer initially boots from. The OS usually maps the BIOS into it's address space to make it available. There's probably a more precise technical description available somewhere on the net, try searching for "boot process"

cheers

CMOS RAM stores the BIOS configuration i.e. disk boot order etc. FYI the CMOS battery provides backup power for this chip as well as the real time clock when the computer is off. The boot strap code is stored in the BIOS EEPROM.
