BIOS in Windows® 7 System
What is the significance of BIOS in computer operating on Windows 7?
The BIOS of a computer software and is the first code run by a system when powered on. The primary function of the BIOS includes loading and starting an operating system. When the system starts up, the first job for the BIOS is to initialize and identify system devices such as the video display card, keyboard and mouse, hard disk, CD/DVD drive and other hardware. Then BIOS locates software held on a peripheral device, such as a hard disk or a CD, and loads and executes that software, giving it control of the system. This process is defined as booting, or booting up, which is short for bootstrapping.

BIOS in windows 7
BIOS is a set of instructions which a computer uses during the booting process. It is a firmware located inside of the system and designed in such a way to protect it from disk failure. During the POST (Power on Self-Test) process, the instructions are pulled from the BIOS. This procedure is necessary to ensure that all attached peripheral devices to the system and functionality needed for a successful start, such as use of memory, a keyboard and other parts. If errors are detected during the POST, the BIOS instruct the system to give a code which reveals the problem.
Tips to open BIOS
BIOS can be viewed as the gateway to a system brain. The access depends on the motherboard programming in which some would allow access by pressing 'F1', 'F2', or 'Del'. To know which key to press, at the initial stage of booting, a message would come on the screen which specifies that right key for entering setup. You may perform a cold boot or a warm boot where in a beeping sound is heard to indicate initialization of the boot process press 'F2' (or any other proper key) as soon as the system identifies the hard disks. As soon as you see the message: “Press Del for Setup” or just by press the suitable key from start up till you really enter.
BIOS update is very important. Update the BIOS on your system only if the newer BIOS version solves a problem you have. BIOS updates for a computers is not recommended if not needed. Downgrading the BIOS to an earlier version is not recommended as it may not be supported. An earlier BIOS version might not contain the support for the latest processors, bug fixes, critical security updates, or support the latest board revisions currently being manufactured. Before you initiate a BIOS update, be sure to read and precisely follow the update instructions.
