Not needed - it works! The strange thing is that there are no
console messages when inserting the SD and CF cards (both
do work), in contrast to what happens if I use a regular
USB stick.

I'm still frightened as

	# true > /dev/da0

suggests that something important might get overwritten. :-)

Yes, when things were a bit more standardized and a bit
less arbitrary... many years ago. :-)

That must have been sometimes with FreeBSD 5 or 6, if I remember
correctly. Don't get me wrong, I'm always fast at complaining
about the system's ability to do simple things that were no
problem in the past, even if that's not fully the case. :-)

Now as I know HOW this should work, it will be no problem to
create a scripted solution for accessing those slots. Glad
I can use them. With usable speed.
