Updating BIOS (Basic Input Output System) is moderately easy, once you understand how the program allows your computer to operate. Before the operating system loads, the BIOS detects and initializes various chips, activates the boot program and runs a POST (power-on self-test). The BIOS uses a series of beep codes to report the status of the POST and alert you when components are failing.
Facts
Modifying your computer's BIOS settings can reduce the time it takes to boot up your computer. You can disable logo screens, drive channels and change the boot sequence. If you do not use external devices, such as Zip drives, external modems, printers and serial mice, you can turn them off in the BIOS. When you disable these devices, Windows operating system will not load the drivers. Your computer system will be able to speed up the boot process.
Significance
Before you attempt to upgrade your computer's BIOS, make sure you know the BIOS and motherboard name, plus the revision or version number. Read the motherboard manual and become familiar with the functions that the BIOS performs. Keep your BIOS information handy, and visit the motherboard manufacturer's website at least once a year to download updated BIOS files.
Function
The BIOS files are usually listed as BIN, ZIP or EXE files. BIN files are binary files that are programmed into your BIOS by a process called flashing. The Flash utility overwrites your old BIOS and copies the new one into the motherboard's EPROM (erasable programmable read-only memory) chip. ZIP or EXE files contain the binary BIOS update file and the Flash utility program.
The Flash utility program usually runs the file from the DOS (disk operating system) command line. Some motherboard manufacturers have released Flash utility programs that run the file in Windows.
Benefits
Updating and customizing your computer's BIOS can improve stability, add new features, reduce boot time and fix system glitches. You can turn hardware devices on or off and adjust the CPU (Central Processing Unit) and memory.
Warning
You should not change your computer's BIOS settings, unless you are familiar with what they are and how they work. Incorrect settings can lock up your computer or worst, damage the hardware. Backup your BIOS and store it on your hard drive before you perform an update. Follow the BIOS Flash program instructions carefully. Do not interrupt the install process, because this may cause serious problems to the motherboard and you may not be able to boot up your computer.
