48c1c25ba5 Make the bootselector configurable by fdisk. Add a -B flag to this 
effect (i386 only of course). Also change one branch in the
bootselector code to an explicit 16 bit one, and check both
the boot menu and partition tables to see if the partition
requested by the user should be booted. This check just in case,
should the bootselector menu and partition table get out of sync
somehow. (mmm, bytesqueezing)

faf59c0aba Initialize drive number in DL (not done by some BIOSs). 
If you want to use 32-bit addresses, be sure to init the high bits, too.
Some additional register saves around BIOS calls (just in case).

70698891e2 When estimating the number of cylinders in the BIOS geometry, use the 
total number of sectors as reported by disklabel.d_secperunit rather
than multiplying out the disklabel geometry, which is less accurate.

1b063875bf Upgrade for non-interactive use. Interactive use is nearly unchanged. 
-i no longer implies -u, -i now does not use the entire first track
because some BIOSes refuse to boot from a partition in the first track.
-s renamed to -S, new -s for non-interactive setting of a partition's
id, offset and size.  Updated documentation to match.

9b746f76a4 Add code to look at the existing partition entries to deduce the 
translated geometry of the disk.  This code will only change the
disk geometry if it can find a geometry which is consistent with
all partition entries, so it's very conservative about choosing
a new disk geometry.  Under some circumstances, it will choose a
number of cylinders which is a little lower than it needs to be,
but this code is enough so that you can create new partitions
with the correct physical addresses.

The right solution to this problem is to have the boot loader
communicate the BIOS geometry of each disk to the kernel, in a
manner similar to the symbol table, and then provide a kernel
interface to get at that information.  I'm unfortunately not
really qualified to make such a change, and I want something
that works better than the status quo.
