Vampire 500 V2+ on A2000 ? (with Megachip and RomSwitcher)

You can't use a kickstart switcher with the Vampire AFAIK.  My A2000 would not boot with the original kickstart left in the socket.  

Is this still the case? I'm receiving my Vampire 500 v2+ with an adapter shortly and I'm wondering if I still have to remove KickROM 3.1 and the original 68000 CPU from the sockets (using an Amiga 2000 Rev 6.2). It would be nice if everything could be left in place, so that I just need to remove the Adapter+Vampire to get the A2000 to it's original state.

My Vampire 500 v2+ and the CPU slot adapter arrived a few days ago. The Vampire works in my Amiga 500 with Rev. 8A Board (68000 & KickROM 2.0 removed). On my A2000, I removed all additional cards and connected the Vampire with CPU Adapter (68000 and KickROM 3.1 still installed). Unfortunatly I got no startup sound and the machine didn't boot. After removing the original CPU, the screen turns black at startup and after 25-30 seconds, the KickROM screen appears. After that, the machine is really quick but I'm wondering why the startup takes so long (it's much faster on the A500).

The specs of my A2000:
- Mainboard revision 6.2
- 68000 & KickROM 3.1 removed
- CPU slot Adapter from Acill
- No other Zorro II cards inside at this time
- 1MB ChipRAM

Could this be a problem with different chip versions? A2000 runs currently with Agnus 8372A, A500 has a 8375. I will get a DCE MegaChip tomorrow, perhaps this will solve the problem?

Vampire has been updated to Gold 2.5.

Edit:
Problem solved - if you have no CF-Card/IDE-Disk attached on the Vampire IDE-Port, there's a boot-Delay on A2000. I attached my CF-Adapter with a new SanDisk CF-Card today and the A2000 booted immediately to the KickROM screen.
