The bad news, is I moved the exact same setup over to my Amiga on the PC Bridgeboard (ISA slot) side, and it didn't work. Fdisk said "no fixed disks" Adisk said "Read Error".
The IO port on that card are fixed to 0x300-0x31f (on some IDE XT cards it's configurable). You might have a conflict, have you tried it with just the bridgeboard and ide & no other cards?
It may also be a bios conflict, this thread
