Inside, you'll find the necessary BIOS file and likely a README or text file that will walk you through updating to the new BIOS version. From there, you choose the BIOS-updating option, select the BIOS file you placed on the USB drive, and the BIOS updates to the new version. Many OEM tools no longer run in Windows, they reboot the system, then update the BIOS in a pre-boot environment, where the BIOS can update more safely.
