fit3 protocol driver does not support accessing IDE control registers (device control/altstatus). The DOS driver does not use these registers either (as observed from DOSEMU trace). But the HW seems to be capable of accessing these registers - I simply tried bit 3 and it works! The control register is required to properly reset ATAPI devices or they will be detected only once (after a power cycle). Tested with EXP Computer CD-865 with MC-1285B EPP cable and TransDisk 3000.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
