Well I'm keeping both in the machine since both have memory on them.
2MB on the 2091 and 4 on the GVP. I'm hoping WB can use the 6MB.

feed it to both of them directly. I have 2091 so it works this way as
well.

remove the autoboot jumper (on one of the controllors - i suggest 2091
since its a slower one. theres a autoboot jumper on bottom next to ram
sockets. set to disable.) frankly i dont get why keep both
controllers... oh ok unless you want amix on it... get a scsi cable and
connect several hard disks all to the gvp scsi...
first prep the hard disk then format it. then install wb.
let me know if you want a 68030 commodore accel board, eventually its
going on ebay.
