Managing and updating your bios
The BIOS then communicates directly with the hardware to carry out the functions.
It is usually stored on a Flash memory chip on the motherboard, but sometimes the chip is another type of ROM.The rate of technological development in the PC industry is such that motherboard manufacturers tend to release BIOS updates on a regular basis, as each new version typically offers improved performance, stability, or compatibility.Users can update their BIOS to it’s latest version, either by replacing the chip on which it’s stored or by reprogramming the chip using a process known as “flashing”.On some systems, instead of seeing this POST screen, you may just see a 'BIOS logo' screen instead.
You can usually press the Tab key to switch to the POST view, or you can turn off the BIOS logo in your BIOS settings.
The BIOS software has a number of different roles, but its most important role is to load the operating system.
