Updating your system UEFI BIOS

The Unified Extensible Firmware Interface (UEFI) BIOS is a part of the system programs that make up the
basic layer of software built into your computer. The UEFI BIOS translates the instructions from other
software layers.
Your computer system board has a module called EEPROM, also referred to as flash memory. You can
update the UEFI BIOS by starting your computer with a flash update optical disc or flash update application
running in the Windows environment.
In some instances when you add software, hardware, or a device driver, you might be informed that you
need to update your UEFI BIOS in order for the new addition to work properly.
