A complementary metal oxide semiconductor (CMOS) is a type of integrated circuit technology. The term is often used to refer to a battery-powered chip that is found in many personal computers that store some basic information, including date and time and settings configuration system, which is required by the system input / output base (BIOS) to start the computer.
The name is somewhat misleading, however, as most modern computers no longer use a CMOS chip for this function, however, use another form that is non-volatile memory. CMOS chips are still found in many other electronic devices, including digital cameras.
What is CMOS and what function? In computers, CMOS control various functions, including the Power On Self Test (POST). When the computer's power supply lit, CMOS running a series of checks to ensure the system is functioning properly. One inspection is included to calculate random access memory (RAM). It usually slows down the boot, so some people disable this feature in the CMOS settings, choose to boot faster. If installing new RAM is better to activate the feature until the RAM has been checked.
After POST is completed, CMOS runs through other arrangements. And format the hard disk is detected, together with the Redundant Array of Independent Disk configuration (RAID), boot preferences, presence of peripheral, and tweak overclocking. Many settings can be manually changed in the CMOS setup screens to improve performance, but changes must be made by experienced users. Change the settings that are not appropriate to make the system unstable, crash, or even prevent the computer from booting.
CMOS configuration screen is accessed during the POST phase of boot up, by pressing a few keys before the operating system initializes. This is usually the Del key, but maybe others on another computer. A line of text will show you the key that will bring users into the CMOS or BIOS setup screen. Changes can not be done from within an operating system like Microsoft Windows ®, but should be done in a DOS session.
There is also an option to protect the CMOS settings by requiring a password to change settings. Changes are saved when exiting by pressing the F10 key, then reboot the computer to use the new settings. Motherboard manual will list all the options available CMOS. This will vary according to the motherboard design and BIOS manufacturers.4.5
