thorpej 6d78b8c024 When fetching the disk's hardware geometry, first attempt the 
DIOCGDEFLABEL ioctl, then fall back onto the DIOCGDINFO ioctl
if that fails.  This ensures that we will get the actual hardware
geometry info rather than any bogus info that might have been
previously written to the disk's label area.

fvdl a6f7895b92 Only use int13 extensions if the sectors can not be read through the 
older CHS interface. This works around stupid BIOSs who report that
int13 extensions are present and functional, but fail when you actually
use them. Like Adaptec SCSI BIOSs.

For the bootselector, there was no space to get the CHS info from
the BIOS. Instead, use a flag that can be set by fdisk. fdisk will
set it if one of the partitions on the disk is out of CHS reach
for this disk/BIOS, so that the bootselector will use int13 extensions.
This isn't so bad, because it needs to be configured via fdisk anyway.

Change the mbr manualpage to reflect some shorter error messages.

fvdl 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)
