That does not work at all starting with Coconet active.
1) Can't read from Drivewire.
2) Immediately after the POKE, I get a string of
?AO ERROR
OK
?AO ERROR
OK
?AO ERROR
OK
etc.

If I use my own copy of HDBDOS, load it into low ram, and use a program to move 
it into the $C000-$DFFF region, and jmp $C002 (I regularly do this), the DSKI$ 
works on Drivewire but again after the POKE, I get the AO ERROR from the Drivepak.

There probably is no good way to make Drivewire and Drivepak co-exist under Disk 
Basic without writing some significant ml code. The HDBDOS and Coconet ROMs and 
techniques are just too different.
One major problem is that the variables in low RAM $149- are used differently. 
Without resetting these variables, I doubt you can flip back and forth between 
HDBDOS and Coconet. Maybe if the variables are saved and reset, this can work.
