Re: Having trouble with two active wscons drivers, wskbd stops working on console

Hi Frank,

Thanks again=E2=80=A6 I have to take a deeper look on that, sounds =
complicated.
I came very far with NetBSD=E2=80=99s documentation about driver =
implementation.
However, the amiga specific information is certainly lacking and =
requires background knowledge which seems to be not documented very =
well.

Regards
Alain
