yes, you can, just put the bios file on a pendrive and plug it into BIOS USB back connector. you have to rename the bios file to suit your motherboard. use bios name changer software. when turn onthe motherboard, flashing process will start, and the back led flash button will start to blink. when that led stop blinking and turn off, the flashing process is over. read more abut this in the manual on bios section.
Not sure if the pendrive must to be formated on FAT32 or not
