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. UEFI BIOS translates the instructions from other software
layers.
Your computer system board has a module called electrically erasable programmable read-only memory
(EEPROM, also referred to as flash memory). You can update UEFI BIOS and the Configuration/ThinkPad
Setup program by starting your computer with a flash update optical disc or flash update tool application
running on the Windows environment.
In some instances when you add software, hardware, or a device driver, you may be informed that you need
to update your UEFI BIOS in order for the new addition to work properly.
