@BoingBoss et al-
Pretty much ANY old Zorro2 style SCSI card will give problems on more modern drives. Both the A2091 and GVP have various upgrades that are required to get them up to speed. I'm not sure one is more evil than the other. (Oh, and BoingBoss - No one would use a A2091 on an A4000, if avoidable. Way too slow, hogs bus resources like a fiend, etc. A4k owners would use a SCSI card on run off the processor card expansion.)
Anyhow, to the issue at hand - A GVP HD card in an A2000 with kickstart 1.3. My first question is have you researched the EPROM version of your GVP controller, and made sure it supports the 1.3 ROM? Most GVP cards have replacement ROMS in them, and some may not support autobooting under 1.3. The solution may be as simple as going with 2.0 or higher for your A2000.
