Is CMOS a smaller part of the system BIOS? (The basic part of BIOS controlling hardware and then CMOS controlling the systems configuration of that hardware)?

CMOS chips pass information to the BIOS (Basic Input/Output System) when the computer is turned on (bootup). CMOS stores information such as boot order (the order the computer looks for information, such as A drive first, C drive second, and so on), real-time system clock, calendar settings, hardware passwords, hard drive configuration settings, and the installed memory (RAM). Essentially the CMOS chip stores data for the BIOS so that a computer can boot up properly.

Thanks Rik. That cleared it all up quite a bit, I'm reading a service tech book and that was just something that it wasn't coming right out and saying but it kind of hinted at, so I was unsure if I was reading it wrong or not. Thanks again. :tazz:
