st351a/x is an IDE 8-bit screw. The type is essentially designed for an 8-bit bus. All controllers on Specki were made 16bit, so you won’t be able to get it to work without a homemade controller and patch software IMHO. Although, on the other hand, the controller for it is a regular address and control bus decoder
without any additional registers; You can easily find in the Internet the schemes for trimming an 8-bit IDE, also Acorn BBC model B, and just remake the sub-spec yourself. Then all that remains is to patch the driver for IS-DOS or SP-DOS.

Regards.

There were ATA controllers for the eight-bit ISA (I found
several models in Total Hardware). In addition, ATA allows you to transfer data not in words, but in
bytes...

Good luck!

There is no need to change the controller. Driver only. For example, Nemovsky would be suitable.

Only this mode is not
supported by almost anything other than compact flash.

DRIVER. And not iS-DOS itself. Estx ve sources.

(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.

977 cyl, 5 heads, 17 sectors = 42,519,040

Note: A "custom" or "user-defined" 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)".
