A computer’s BIOS (basic input/output) is its motherboard firmware, the software which runs at a lower level than the operating system and tells the computer what drive to boot from, how much RAM you have and controls other key details like CPU frequency. Aug 23, 2018.
Is the BIOS on the motherboard?
Typically embedded into your computer as a motherboard chip, the BIOS functions as a catalyst for PC functionality action. Programmed on an erasable, programmable, read-only memory (EPROM) chip, BIOS is stored on this memory chip which retains data when the power source is switched off.

Is BIOS a part of the operating system?
By itself, the BIOS is not an operating system. The BIOS is a small program to actually load an OS.
What does BIOS look like?
The BIOS is the first piece of software your PC runs when your turn it on, and you usually see it as a brief flash of white text on a black screen. It initializes the hardware and provides an abstraction layer to the operating system, freeing them from having to understand the exact details of how to deal with devices.
Where is the BIOS chip on the motherboard?
BIOS is generally located on the edge or corner of a motherboard. Know that you will usually be able to find it near the coin-cell socket. After all, it is the one that has the BIOS setting. Note that CMOS memory is what it’s known by.

How many types of BIOS are there?
There are two different types of BIOS: UEFI (Unified Extensible Firmware Interface) BIOS – Any modern PC has a UEFI BIOS. UEFI can handle drives that are 2.2TB or larger thanks to it ditching the Master Boot Record (MBR) method in favor of the more modern GUID Partition Table (GPT) technique.
How do I get into my BIOS?
To access your BIOS, you’ll need to press a key during the boot-up process. This key is often displayed during the boot process with a message “Press F2 to access BIOS”, “Press <DEL> to enter setup”, or something similar. Common keys you may need to press include Delete, F1, F2, and Escape.
What is BIOS in simple words?
BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
What is inside a BIOS chip?
The BIOS stores the date, the time, and your system configuration information in a battery-powered, non-volatile memory chip, called a CMOS (Complementary Metal Oxide Semiconductor) after its manufacturing process.
Is CMOS a RAM?
Alternatively referred to as a RTC (real-time clock), NVRAM (non-volatile RAM) or CMOS RAM, CMOS is short for complementary metal-oxide semiconductor. CMOS is an onboard, battery powered semiconductor chip inside computers that stores information.
How do I fix corrupted BIOS?
You can do this one of three ways: Boot into the BIOS and reset it to the factory settings. If you are able to boot into the BIOS, go ahead and do so. Remove the CMOS battery from the motherboard. Unplug your computer and open your computer’s case to access the motherboard. Reset the jumper.
What is attached to the motherboard?
Motherboard contains ports to connect all of the internal components. Motherboard carries fans and a special port designed for power supply. There is a peripheral card slot in front of the motherboard using which video cards, sound cards, and other expansion cards can be connected to the motherboard.
What is the difference between BIOS and CMOS?
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. CMOS is a type of memory technology, but most people use the term to refer to the chip that stores variable data for startup.
