Ok, from this I can tell you that your port _is_ working in
8-bit mode - and the drive can detect the EPAT adapter in the external
drive. There's something else amiss, however, as the driver doesn't
seem to be able to find an IDE device on the other side of the adapter.

Please try repeating this experiment after powering everything
(laptop and external drive) off for a few minutes.

It's possible that the drive is in a confused state and is not
responding, even though the adapter is alive and working.

This could also have to do with the port delay - although the
symptoms are not quite right. Try the same command with a delay
of 4.

Can you confirm that this drive works with DOS (or any other OS ?).

Ok, there's no EPP mode on your port.

hunh ? Is that repeatable ??? If so, there's some kind of bug there !
