Your question: "Is their any way of using the ISA hard drive
controler on the PC bridgeboard to work with the Amiga side"
- the answer is *yes* there is.
It's the way I started out many years ago with a 2286 bridgeboard.
You need the bridgeboard Janus software, and jlink command as
I remember. The sequence works like this:
You still have to start a minimul boot with a floppy to
transfer to the PC hard drive after it is mounted. Just
setup the hard drive with two or more partitions, msdos FAT16
and another couuple for the Amiga which you format later.
if you need info send me a message, I believe I have all the
software and details for you.
BTW, is it an IDE/ATA interface (single 40 wire ribbon) or more often
an ST506 ("mfm") interface - two ribbon cables?
