The CMOS is the type of semiconductor the BIOS uses to store data.

For the purpose you're talking about the CMOS setup utility or BIOS setup utility are the same thing. You can access this when your computer boots up by pressing usually DEL, F4, or F8
What's the difference between BIOS and CMOS?
Many people use the terms BIOS (basic input/output system) and CMOS (complementary metal oxide semiconductor) to refer to the same thing. Though they are related, they are distinct and separate components of a computer. The BIOS is the program that starts a computer up, and the CMOS is where the BIOS stores the date, time, and system configuration details it needs to start the computer.

The BIOS is a small program that controls the computer from the time it powers on until the time the operating system takes over. The BIOS is firmware, which means it cannot store variable data.

CMOS is a type of memory technology, but most people use the term to refer to the chip that stores variable data for startup. A computer's BIOS will initialize and control components like the floppy and hard drive controllers and the computer's hardware clock, but the specific parameters for startup and initializing components are stored in the CMOS.

CMOS definition: stands for Complimentary Metal Oxide Semiconductor and refers to the physical makeup of the memory chips used to contain the CMOS memory settings. The CMOS memory settings are used to semi-permanently store information about your hardware: memory amount, number and type of hard drives and floppy drives, number and type of I/O ports (serial, parallel, SCSI, USB, etc.), system bus types (ISA, PCI, EISA, etc.) and some settings related to this hardware. With Plug-and-Play components, Windows 95/98/NT can update some of this information. CMOS memory is not the same as the BIOS (Basic Input/Output System) memory which is stored in ROM (Read Only Memory) or PROM (Programmable Read Only Memory). In some systems the BIOS is stored in Flash EPROM (Flash-programmable Erasable/Programmable Read Only Memory) which is re-programmable without removing the chips from the system using special software.
