so when I try to boot from it I have to do the "hold down both mouse buttons on restart" and select DF2 as the boot device
Can you adjust your boot priorities of any other devices (hard drive partitions, etc.) to be lower, so you don't have to do this?
*SetPatch does make changes to the Early Startup Control screen that if you're having to go back into it each time, might be throwing something off...
*I vaguely seem to recall someone having a problem a long time ago where it would start to boot off the floppy, then incorrectly pull some of the files of the hard disk instead
*I wonder if they even considered the possibility that someone might try to install 3.9 off an external DF2:? I'll have to skim one of my ERD's later to see if there's anything off-hand that might have an issue with this...
TL;DR. I wonder if you shouldn't focus on getting all your hardware issues resolved before starting on software stuff? AFAIK I think you can still buy new internal floppy drives from AmigaKit; they won't match your faceplate but they'd work in a pinch.
