i'd start with pulling out the hard disk card.
then if that works and gives you the floppy disk screen, or boots from the compact flash card, then either leave it at that, or if you want to access your old drive, i'd take the ram off of the scsi card if there is any and see if that works without the ram.
i'm just working with info i've seen from other people and their expirience, but any zorro card that has ram, and allows DMA to/from that ram may have problems.
if i recall correctly, this was the deal with the GVP scsi cards.
however if you are running an A2091 card, there may also be the issue of conflicting scsi.device controlers in the system. the scsi.device from the IDE adapter on the vampire, and the A2091's scsi.device.
hence why i've seen people have success with octagon scsi cards, as they neither have ram, nor identify as scsi.device in the system.
i run my Vampire with the rom installed - it can't hurt to pop it back in to see if it's missing something from the rom.
but yes, with the vamp in the 68k socket that should be fine. i've seen someone run a load of dupont wires from the socket to the bottom of the vampire to run it in the A2000's 5.25" drive bay to be able to access the CF and microSD slots.
if the vamp was on a cpu slot adapter card, you'd have to pull the 68k out of the socket anyway.
hope this is of some help, and that someone with more relevant A2000 expirience can jump in on this too
