The reference it CMOS is regarding CMOS Memory.. or NON Volitile memory.. this comes from the early days with the "PC" .. Once motherboards moved away from switch settings and allowed a greater software controle of motherboard operation and settings.. the BIOS needed some place to store this information .. some systems saved this to a drive (floppy or HDD depending on your wealth) ultimatly this information was saved to a Non-Volitile memory.. and as it would happen .. due to the devices low power requirements esp in system standby mode (memory was battery backed up) CMOS was the prefered memory type,,


not the best with these explainations.. hope that with the link above helps..

Cheers

no, i fully understand how it works. i was just curious as to why the named it after the actuall component. i mean, they havent named anything else by what components they have.

anyways, thanks for the goss
