It appears that the normal SUN1.05 format.dat will work.
I would like to thank the following folks who answered my query:

I just got mine working today. I was thrown off by the fact that Seagate
is decptive about the size of their disks. When they say MB they mean
millions of bytes (1000^2) instead of megabytes (1024^2) which is what
everyone else uses, and consequently I was making the number of cylinders
too large.
--> Sams response to my pointing out that SUN1.05 is really the same
--> drive as the SN11200.
.. I saw that one, but didn't know it was the same drive. My geometry
.. actually produces about 2M more space, but I suppose I should switch
.. to the standard Sun entry just for future compatibility.
Here's the entry I was able to use:
disk_type = "Seagate ST11200N" \
: ctlr = SCSI : fmt_time = 4 \
: trks_zone = 15 : asect = 12 : atrks = 30 \
: ncyl = 1714 : acyl = 1 : pcyl = 1715 : nhead = 15 : nsect = 80 \
: rpm = 5411 : bpt = 40960
partition = "Seagate ST11200N" \
: disk = "Seagate ST11200N" : ctlr = SCSI \
: a = 0, 2056800 : b = 0, 0 : c = 0, 2056800 : g = 0, 0
-- Sam Horrocks ICS Department, UC Irvine Email: sam@ics.uci.edu-------------------------------------------------------------------------- This is the same disk used in the Sparc 10. From the 4.1.3 format.dat:
disk_type = "SUN1.05" \ : ctlr = SCSI : fmt_time = 4 \ : ncyl = 2036 : acyl = 2 : pcyl = 2038 : nhead = 14 : nsect = 72 \ : rpm = 5400 : bpt = 43200
partition = "SUN1.05" \ : disk = "SUN1.05" : ctlr = SCSI \ : c = 0, 2052288
I've got one stuck in an IPC -- works great. -- Eric Pearce | eap@ora.com | O'Reilly & Associates Publishers of Nutshell Series Handbooks and X Window System Guides 103 Morris St, Sebastopol, CA 95472 1-800-998-9938 or 707-829-0515
