Sure, read this. I bounced mail to you so here's the spec sheet. For
everyone's information, I have all the specs for Seagate IDEs, as well
as all Micropolis drives, and will continue to collect them. They are
also archived on msdos.archive.umich.edu for anonymous ftp access in
msdos/info/disk. The strange capital letters in this used to be very
beautiful ansi borders and are now very ugly gibberish.

@DDDDDDDY X = Jumpered; 0 = No Jumper
(1) Bus reset active level. System dependent. A jumper must be
installed on either Bus Reset Hi or Bus Reset Low; the
drive will not function if neither set of pins is
jumpered.
(2) HSP/Assert "/DASP" signal: pin 39 on 40-pin AT/AT
Interface connector. The Host Slave Present jumper and the
Active LED jumper are mutually exclusive.
(3) XT only. These jumpers are used to set the drive type
information to be returned by the drive via the Drive
Configuration register (I/O port 2) or the XT Interface.

Note: A "custom" or "user-definded" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".
* CHECK TO SEE IF YOUR CMOS SETUP HAS A "CUSTOM" OR "USER DEFINABLE"
DRIVE TYPE AVAILABLE. (see below)
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
ZBR = Zone Bit Recording = Variable sectors per track
Already low-level formatted at the factory for AT installations.
Since a User-definable or Custom translation geometry may be used, it
is imperative that the values be written down and kept with your
permanent records for retrieval in the event of CMOS battery failure.
