Unzip the file and insert your USB memory stick. Copy the bootimage to the stick:
dd if=$BOOTIMAGE of=/dev/$USB
Download the DOS flash utility and the new bios file from your mainboard producer's website.
Mount your USB memory stick:
mount -t vfat /dev/$USB $MOUNTPOINT
and copy the Bios flash tool and the new bios file to the stick. Reboot your computer and boot from the USB memory stick. Now you can update your Bios with the DOS utility.
