Found out that connecting DVD drive to a Vampire would slow the IDE down too much. So looking for another way to connect the drive to A500
Funny, I was just logging on Amiga.org to ask the same question.
Like you, I have a vampire with the Checkmate 1500+ with the the zorro II/86 pin backplane.
I tried a buddha controller 20th anniversary in the zorro II slot. It causes the Amiga to hang at boot.
I also tried a trumpcard pro. it also causes the amiga to hang at boot if I have autoboot on. If I turn autoboot off, on the trumpcard, I can get the vampire / A500 to boot. I have not tried to mount devices later.
Oddly enough I could get the trumpcard pro to autoboot in an A2000 with the vampire in it.
The buddha in the same a2000/vampire would not autoboot, but would not stop the vampire from autobooting.
Just FYI, I tried both the trumpard pro and the buddha in the A500/checkmate with zorro II and no vampire (ie just an 68000) and everything works fine with both zorro II cards.
