        Thebios can only be updated in DOS mode. Basically you go into bios and set the usb drive as the primary boot drive. Then you can issue a command from the DOS prompt. Make sure you also have the AUFUDOS.exe file copied to the usb drive. You can find it in the same folder where live update downloads the bios files.
