+# handling of lost ticks
+#
+# @delay: continue to deliver ticks at the normal rate. Guest time will be
+# delayed due to the late tick
+#
+# @merge: merge the missed tick(s) into one tick and inject. Guest time
+# may be delayed, depending on how the OS reacts to the merging
+# of ticks
+#
+# @slew: deliver ticks at a higher rate to catch up with the missed tick. The
+# guest time should not be delayed once catchup is complete.

+#
+# Policy that BIOS should use to interpret cylinder/head/sector
+# 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.
