Ok, it may sound stupid, but what is CMOS? And how to use it?

CMOS is short for Complementary Metal Oxide Semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits.

Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them desirable for use in battery-powered devices, such as the CMOS memory chip that holds the date, time, and system setup (BIOS)parameters.

This makes senses and clears everything. Thanks.

If I undestood correctly, if I change bios settings, I change CMOS settings?

In PC lingo, yes.
