A4000 DF0: as external..
 

Hi,

I really don't understand the use of jumper J352 (Redirect DF0:).
When is on 2-3 position (Internal DF1: and DF2:, External DF0: and DF3:) the internal is still DF0: !

The jumper routes SEL2 or SEL0 to pin 21 of the external drive connector, so the 1st external drive would become DF0.

However the internal floppy connector is unaffected by the jumper, so you must unplug the SEL0 drive in there or jumper it to listen to SEL1.
