The BIOS for your computer is classed as firmware.
Drivers are Windows components used to interface between devices (hardware) and software. Drivers are downloaded and installed under the control of Windows. A faulty driver upgrade may cause the related device to not be usable or may cause Windows to crash. It is usually relatively easy to recover.
A BIOS upgrade should be downloaded only from the manufacturer of the motherboard of your computer. It will come with installation instructions. Take great care - a faulty BIOS change (e.g. one for another motherboard version) can possibly prevent the computer ever switching on again which is rather difficult to fix!
I would have to say that you would need the updater software and the actual BIOS update (firmware)
The easier question would be what IS a reason to update. If your software or hardware does not support the functions they were meant to and your BIOS has firmware that can make it function, then this is reason enough to consider flashing yur BIOS. Upgrading BIOS is something you simply don't do on a whim as you could adversely compromise behavior and possibly indirectly damage other hardware.
yes - If the BIOS of your computer is infected then, since it is hard-coded (firmware) on a chip, you could have irreparable damage. Also most anti-virus programs work within your operating system (Windows or MacO/S) so they don't detect BIOS infections. The only way to repair your BIOS is, if it can be, to Flashit. This is the process used to update the firmware on your BIOS chip. Check your computer or motherboard manufacturer to obtain the flash application, and the instructions for running it. Flashing the BIOS should place a new, uninfected version of firmware on the chip.
Firmware
Firmware refers to programs that are fixed, low-level operations. Since the BIOS is hard coded on a chip, it can be classified as firmware.
Device drivers and firmware(Example: Bios).Operating system(Example: Windows).Servers.Software development tools.Utility software.
The real question is, how do you know your BIO's have a virus?If for some reason they really are corrupt. You will have to flash the firmware. If that's not possible the get another motherboard.
That is for sure a firmware issue, update the drivers and restart the system.
CD/DVD drives and printers use Firmware
Softwareis programs which can be installed and used by the user for a specific purpose. Firmware on the other hand is used by the computer system for maintenance and security purposes, an example for thisis Windows Update.
Not sure. Why not downgrade?
It's called firmware.
