-#
-# @auto: If cylinder/heads/sizes are passed, choose between none and LBA
-#        depending on the size of the disk.  If they are not passed,
-#        choose none if QEMU can guess that the disk had 16 or fewer
-#        heads, large if QEMU can guess that the disk had 131072 or
-#        fewer tracks across all heads (i.e. cylinders*heads<131072),
