+#         of ticks
+#
+# @slew: deliver ticks at a higher rate to catch up with the missed tick. The

+# addresses.  Note that Bochs BIOS and SeaBIOS will not actually
+# translate logical CHS to physical; instead, they will use logical
+# block addressing.
+#
+# @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),
+#        otherwise LBA.
+#
+# @none: The physical disk geometry is equal to the logical geometry.
+#
+# @lba: Assume 63 sectors per track and one of 16, 32, 64, 128 or 255
+#       heads (if fewer than 255 are enough to cover the whole disk
+#       with 1024 cylinders/head).  The number of cylinders/head is
+#       then computed based on the number of sectors and heads.
+#
+# @large: The number of cylinders per head is scaled down to 1024
+#         by correspondingly scaling up the number of heads.
+#
+# @rechs: Same as @large, but first convert a 16-head geometry to
+#         15-head, by proportionally scaling up the number of
+#         cylinders/head.
