Help!

I have an IBM/XT with a 20 Meg Tulin and I want to add a 30 Meg Seagate
Full Height (ST4038). The controller that I am using is the Western
Digital Auto Configuring WX2. I have tried a bunch of different setups
with this thing and I am at wits end...

Drive C -- 20Meg Tulin 612 Track 4 Head (currently in operation)
Drive D -- 30Meg Seagate 733 Track 5 Head (want to add)

I have both drives cabled correctly and I now need to know the parameters
for the Western Digital ROM Format program. I have tried various numbers
in an effort to get this Seagate drive to operate half way.

Currently the jumpers on the Western Digital Card are:

	3, 5	ON
	Others	OFF

I have had jumper 5 off so that the controller will format drives using a
user defined table, but I have not hit upon the magic numbers needed to
make the Seagate ST3048 (Full Height AT Type 8 & 20) work.

The numbers that I need are:

	Interleave Factor	What works best?
	Total Number of Cyls	Have used 733
	Number of Heads		Have used 5
	Reduced Write Cyl	Drive doesn't use this so what is the
				phoney number?
	Write Precomp Cyl	???
	Correct Error Burst	???
	CCB Option Byte		???


All replies are welcome. Thank you.
