I'm trying to create a disktab entry for a Fujitsu 2266S drive.
It is translated to 1023 cyl, 32 sec/track and 64 tracks/cyl by
my AHA-1542B controller.  I've gotten the first line of the
disktab entry OK, but need help getting the last few lines to
match my desired layout.

I'm already using 331 cyls for MS-DOS.  I'd like to have a
32M root (is this size OK for most things?), 32M swap, and
the remainder of my disk (692 - 64 = 628 cyls) for /usr.

Now I know that 386BSD's partition a is /, b is swap, and
c is /usr.  What about the h partition that appears in most of
 the initial disktab entries? Do I have to define partition d at all?

Here's my disktab so far:

fj2266|Fujitsu 2266S: \
	:ty=winchester:dt=SCSI:se#512:nt#64:ns#32:nc#1023:rm#3600:\
	:pa#65536:oa#677888:ba#4096:fa#512:ta=4.2BSD: \
	:pb#65536:ob#743424:tb=swap: \
	:pc#1286144:oc#808960:bc#4096:fc#512:tc=4.2BSD:

Does anyone see any problems with this?  I know that it may
take a minute or two to check the math, but any errors?

Thanks,
  Dave Paoletti :)
