Check if there's no active partition after MBR editing.
Ask for own MBR to be installed if we're booting from out of CHS range.
Ask for bootselector to be installed if > 1 OS, and configure it.
* Use structures, not 2-dimensional arrays..
* Use the DIOCGDEFLABEL ioctl to get the disk information,
to avoid confusion with (older) labels.
* Don't ever call fdisk for partitioning. This was the
source of much confusion.
* For the i386, use the BIOS geometry information passed by
the bootblocks.
Lots of things left to do, but it's a start.
* Split bios geometry and MBR partition editing code formerly in
arch/i386/{md,fdisk}.c to mbr.c in mi directory.
* Leave /sbin/fdisk parsing/handling code in separate file,
we may want to change it later. move to mi directory.
* Create mbr.h with declarations for MBR/BIOS-geomotry code.
#include "mbr.h" in i386 md.h.
* Use symbolic names for 386bsd and new NetBSD partition IDs.
Handle MBRs with both 386bsd and NetBSD partitions less stupidly.
