Does anyone know the best way to configure a Maxtor 8760E disk on a
WD1007V-SE2 controller in a 386 AT system when you want a small bootable
DOS partition followed by a big UNIX partition, without wasting most of
the disk?

I have:

	Intel System 402 (AT386-type box with a 25MHz 486 and the
				latest Phoenix BIOS)
	Western Digital 1007V-SE2 controller (ESDI)
	Maxtor 8760E 5.25" FH disk (1632 cyl x 15 hd x 54 sec/trk for a
				formattad capacity of ~ 678MB)
	MS-DOS 3.30
	Intel UNIX System V/386 Release 3.2.2

What I want is:

	Partition 1: 32MB DOS bootable
	Partition 2: 640MB UNIX, to be chopped up into filesystems.

What I would love most of all is:

	An exact cookbook procedure for creating the above. :-)

What I don't understand right now is:
	
	* Should I enable or disable the 1007V's translation mode?
	  Does that mode need their BIOS INT 13H code to make it work
	  right?  If so, how will the BIOS-free UNIX driver cope?

	* How do I tell UNIX or DOS fdisk() programs about cylinder
	  numbers over 1023?  The fdisk on Intel's supplied UNIX boot
	  disk seems to do 10-bit truncation on numbers at the strangest
	  places, making hash of the partition table.  Will I have to go
	  in with Norton and patch it myself?

	* After screwing around with SETUP and FDISK for a while, I no
	  longer seem to be able to boot DOS from the hard disk even
	  when I run FDISK from scratch and FORMAT the resulting
	  partition.  The system hangs weirdly.  Will I have to do a low
	  level format to clean this up?

Any advice anyone can give me would be appreciated.  I know I'll beat
this thing, but the curve of ignorance is pretty high at the moment.  :-)
