Fine for me if it works ... I just read on a couple of web pages that
ID 7 is normally reserved for the host, that's why I limited the GUI to
0-6 only. But if it normally does not cause problems, I can change that
for sure.

I'm currently re-working the IDE code to get away from the hard-coded
"master/slave" config settings to a more generic enumerated approach
(IDE0 + IDE1). With that it should finally be easier to support
multiple IDE interfaces, too. But I don't have real plans to implement
this, there are other more important things on my queue...

No, I was not able to find the issue, so HDDriver currently still locks
up in certain cases (when loading bigger blocks in one go) in Falcon
mode. Help would be very appreciated ;-)
