Try taking 2MB off the GVP card. Even though the 2630 has only 2MB installed, it might be allocating the full 4MB of address space.
No - I had a similar setup - the 2630 only allocates the actual memory it has.
Can you explain what exactly you have hooked up to the SCSI cable ?
So literally starting from the GVP SCSI internal connector.. and if the drive has termination set or not... and the final terminator (drive or actual cable connected terminator) + what SCSI id's you have set of course
I do assume you have no external devices connected for now.
Also: any other zorro cards in there ? If so... which ones ? take them out.
