It can also be fulfilled by a regular user as well, but at their own risk.& &The Basic Input/Output System (BIOS) is a highly important piece of software that loads the currently installed operating system and tests all hardware components – so make sure you flash it correctly.& &When it comes to changing the BIOS version, the update utility searches for a compatible package in any given location or on the web and, if found, it will automatically install the desired build, if and when your approval is given.& &Do take into account that failing to perform the installation could seriously damage your system, and the faulty BIOS might even render it unusable.& &Therefore, if you intend to upgrade your BIOS, hit the download button, get and install the package, and run the utility to check if a newer version is available. Don’t forget to check with our website as often as possible to be up to date with the latest releases.&&
