Updating a bios
Accessing the BIOS is done by pressing a particular key at computer bootup.
This key will vary depending on who manufactured the computer or motherboard. This key will often be displayed somewhere on the screen when the computer first boots.
It tells us to press DEL to enter Setup (which is another name for the BIOS menu system).
Figure 1 shows an example of a typical white-box motherboard’s BIOS. This shows a computer with an Intel motherboard booting up; the screen tells us to press F2 to enter the BIOS.
If, however, you do not see it, and instead there is a splash screen with the manufacturer’s logo, simply press the Esc key to remove the logo.
This will then display the access key (as well as other bootup information).
Regardless of its form, the BIOS chip on the motherboard is also known as the system BIOS.
The BIOS is perhaps one of the most important, and most misunderstood, code for booting a computer.
In this article, David Prowse explains the BIOS process, the importance of updating, or “flashing,” and offers steps for completing this update process.
Be sure to read your motherboard's manual thoroughly before attempting to flash your BIOS or update your motherboard's chipset drivers.
If you are not comfortable in performing the steps indicated by your motherboard's manual, please contact your motherboard manufacturer or system assembler for assistance.One of the most common questions I receive about the BIOS is how to flash it.
