Most of the time the BIOS have an upgrade available, to know if you have BIOS upgrade you need to visit the pc maker site. Most computer makers such as IBM, Dell, Compaq and Packard Bell have these updates on their web sites.

After you find the manufacturer that provided the BIOS code, the next step is to determine whether the BIOS can be upgraded. Unless you are very certain that your BIOS needs to be updated, check with your hardware manufacturer. If you improperly flash (update) your BIOS, you may be unable to start your computer, and this may result in data loss or other problems....

Before you do anything to your BIOS, it's always a good idea to record the settings on a sheet of paper that can be kept in a safe place. The process of updating the BIOS can be summarized in the following steps:

1. Determine your BIOS version.
2. Obtain the appropriate BIOS update.
3. Prepare a BIOS flash disk.
4. Flash the motherboard BIOS....

The BIOS is special software, stored on a chip, that interfaces the major hardware components of your computer with the operating system. It provides an interface between the operating system and the hardware, acting as an intermediary between a computer's hardware and its operating system. Without the BIOS, the PC's operating system would have no way to communicate with, or take control of, the hardware.

The BIOS is a crucial component of any computer. If the BIOS is not configured properly, you may be able to boot up the operating system and run it for a while. However, the system will become unstable and eventually crash....

Every time the computer is powered on, the BIOS immediately performs a number of tasks from initializing the microprocessor to initializing and testing hardware to starting the operating system. Here is a sequence of steps of how the BIOS boots:

1.- When power is applied to the system, the power supply will generate a power good signal which is received by the motherboard timer. When the timer receives this signal, it stops forcing a reset signal to the CPU and the CPU begins processing instructions....

BIOS has several functions in a computer but its most important task is to load the operating system. BIOS provides the microprocessor its first instructions upon activating the computer. Some of the common tasks that the BIOS performs include:

A power-on self-test (POST) for all of the different hardware components in the system to make sure everything is working properly. During this process, the BIOS checks a specific memory location (address) on the computer (0000:0472). Information on whether the computer is being started from an off position (cold boot) or from a restart (warm boot) is stored at this location....

BIOS is the acronym for Basic Input/Output System also known as Binary Input/Output System, Basic Integrated Operating System and occasionally Built In Operating System. The BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions. The BIOS is what starts the computer after you turn on the power to your computer.

The BIOS is typically placed in a ROM chip that comes with the computer (it is often called a ROM BIOS). This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Because RAM is faster than ROM, though, many computer manufacturers design systems so that the BIOS is copied from ROM to RAM each time the computer is booted. This is known as shadowing....
