Document the history of fdisk based on the original post to comp.unix.bsd by Julian Elischer [1] and the Mach 2.
5 Installation notes [2].
I was unable to pin point the exact version of Mach the fdisk utility appeared as I could not find documentation
older than version 2.5 & no source code or repo history.
fdisk utility appears as a separate utility[3] in v2.5. Due to this, I have avoided stating the exact version fd
isk first appeared in Mach.

being defined in <sys/diskmbr.h>. Instead give the symbols here a
"PC98_" prefix. This way, both <sys/diskmbr.h> and <sys/diskpc98.h>
can be included in the same C source file.
The renaming is trivial. The only gotcha is that DOSBBSECTOR is
also redefined from 0 to 1. This because DOSBBSECTOR was always
used in conjunction with an addition of 1. The PC98_BBSECTOR symbol
is defined as 1 and the expression is simplified.
Note: it is not believed that ports are seriously impacted; or at
all for that matter.

vs 4), supress all unused partition output unless -v is specified.
This makes operating on a 'typical' disk with one partition less
painful. The 30 lines needed for the empty partitions no longer
scroll the useful information off the screen. When the user requests
a specific partition, the unused information is not suppressed.
Also add the partition name to the -s output.
Initialize the partition name to 'FreeBSD' when -I is specified.
o Also, fdisk_pc98 appears to support -i, so add it to the man page.
o Ditto -v
o Change the name from PC partition table maintenance program to NEC PC-98x1
partition table maintenance program, since it is possible to have a DOS MBR
formatted disk on FreeBSD/pc98 now (although we don't install any tools for
this).
o Merge the -I switch from i386 verison to initialize the partition table
to use the maximum amount possible for a single FreeBSD table.
o Improve warning when the geom method fails (which I think it
always will until geom_pc98 is updated to respond to this ctl message)
o when writing out the boot sector, we have to write out a minimum of
1024 bytes or the sector size. This is different than the i386 case where
we need to write out a minimum of 512 bytes (which is also the minimum
sector size). We already handle this difference on reading, but didn't
in writing, so attempting to write a new partition table would fail.
o Add MID to the -s output, since pc98 users are likely interested in
both of these parameters.
# I can now initialize disks on my pc98 machine either by -I or by
# manually entering the parameters. I don't know if fdisk -B works or not,
# since I'm not willing to risk my only working boot disk to test it..
