I had the same problem with ROM 2.0 & 3.1
Now with the lastest Roms on the A2630 card, I don't see this opening screen to choose 68000/68030. You have the pbs with 68000 because you used CTRL+A+A to make a reboot after choosing 68030 without result => switch off by the powersupply and choose directly 68000.
Becareful also with A2091 old ROM + AMIGA with ROM 3.1 !
