Every motherboard contains a volatile memory chip on which there is a set of instructions known as BIOS. The BIOS program starts as soon as a user switches on the PC. Flashing the BIOS might be necessary whenever a feature or program within the PC is not working properly. Sometimes there can be problem related to the motherboard which the BIOS would pick up on. To find out more and get a better understanding the BIOS, have a look at the article below.
What is the BIOS?
BIOS stand for Basic Input/Output System
The BIOS is a set of instructions contained on a volatile memory chip built onto your motherboard. When a PC is turned on, the BIOS program is initiated. It performs a hardware check ensuring that all crucial hardware (video card, a CPU, memory) are present and working properly. If any problem is detected it will inform you via beep codes. A startup screen is displayed if everything is OK. A memory check is done, other hardware are identified, device are configured as needed, Boot drive is identified, and then control and priorities are handed over to the boot sector on the boot drive, which launches the operating system. Note that all these procedures are done independently from the operating system used.
Upgrading the BIOS
Upgrading the BIOS of your computer's motherboard, is also known as flashing the BIOS, which consists of downloading the correct BIOS file, the proper CMOS chip flashing software, rebooting the PC into DOS mode, applying the correct commands and waiting until the update is complete. BIOS updates can add new features and provide significant stability to your system.
Reasons to flash the BIOS
among the features and options contained in the BIOS, if one of them is not working properly upgrading the BIOS can solve this problem. Corrections made by manufacturers are accessible with newer BIOS versions.
Supporting larger hard drives and the latest processors:
allows you to configure your PC to maximum size for hard drive and adjusting your motherboard to accept newer processors.
Make sure that you have all the necessary information about your motherboard and have the right CMOS chip flashing software before performing this operation, or things can turn out badly.
