	  To test your BIOS image in Qemu:

	  Using genimage

	  --------------



	  If you use genimage to generate your complete image,

	  installing Grub can be tricky. Here is how to achieve Grub's

	  installation with genimage:



	  partition boot {

	      in-partition-table = "no"

	      image = "path_to_boot.img"

	      offset = 0

	      size = 512

	  }

	  partition grub {

	      in-partition-table = "no"

	      image = "path_to_grub.img"

	      offset = 512

	  }



	  The result is not byte to byte identical to what

	  grub-bios-setup does but it works anyway.
