The term “BIOS flashing” refers to the procedure of upgrading your BIOS introductions to the latest version. Upgrading BIOS instructions can have several advantages. For instance, your old BIOS may not be able to recognize many newer drives, but once the instructions are updated, it will often be able to work with those without a hitch. Besides, you will get many other benefits as well, which include:

1. Support for latest processor models: If your BIOS ROM module is a few years old, it may not be able to recognize many newer processors. A simple update of the BIOS module is usually enough to solve this problem.
2. Support for high-capacity hard disks: Modern, high capacity hard disks may not be supported by older BIOS modules. Update the BIOS, and this problem will simply vanish.
3. Fixing odd bugs in BIOS ROM: There may be some services that were mentioned in the motherboard manual, but not provided by the motherboard properly. This does not necessarily mean that you have received a faulty motherboard. It may be due to a bug, which will go away simply with an upgrade of the BIOS.

Sounds all good, right? It is, but there is a big risk when you are upgrading the BIOS nonetheless. Your motherboard, the very backbone of your PC, needs the BIOS to start up the drives in the PC every time you turn on the power switch. So, if something goes haywire during your BIOS upgrade procedure, you will usually have to buy a new BIOS ROM chip. In case of old motherboards, replacing the ROM chip is often not possible, so if you have one of those, you may have to buy a new motherboard altogether. So, unless you know exactly what you are supposed to do, DO NOT attempt to update your system BIOS by yourself. Besides, if all of your drives or other hardware devices are getting recognized by the BIOS without any problems, then you simply do not need to upgrade your BIOS.

There are a few procedures that you must follow in order to flash your BIOS. Firstly, make sure that the version of the BIOS upgrade is correct. If you are not sure of the version, find it out before you proceed any further. Guesswork can expensive here. Secondly, never, under any circumstances, turn off your PC while updating the BIOS. Finally, if you are not sure about any step of the procedure, seek help of a qualified system engineer.
