You can loop mount the image, or set it up so mtools treats the the image file as a drive, and then copy your new BIOS file to it. The disadvantages of it is if you mess up your BIOS update, you may not be able to get at the image file, and you can not save a copy of the current BIOS to it. If you have partition 1 as your /boot partition, and you have wbiosboot.img as your image file, you can have an entry like this: title BIOS update root (hd0,0) chainloader /wbiosboot.img To loop mount it for updating the files, you can uses something like: (assuming you have a /mnt/image directory) mount -o loop /boot/wbiosboot.img /mnt/image A better way, if you can boot from a USB drive, would be to have a bootable USB "pen" drive set up to do the BIOS update. That way, you can save the current image before you update. What ever method you use, it is a good idea to have a CD with a good BIOS image on it if your MB supports restoring from a CD. Most of the motherboards I have can flash the BIOS from an image on a floppy or CD in the case of a failed upgrade, as long as you have the correct file name on the media. But they do not check for a USB drive, so if you can no longer boot from the hard drive, or a USB drive, because your update failed, this may be your only recovery method.
