I'm running Kickstart 1.3, Workbench 1.3.3.
Additional info:
My A2091 controller is working perfectly fine with my hard drive, and on boot, there is an attempt to read the CDROM (I assume to find a bootable medium).
My CDROM jumper settings:
SCSI ID 2, Terminate on, SCSI-II compatibility mode off, SCSI parity check on.
I've noticed a lot of things referring to gvpscsi.device on other posts, but as my SCSI controller is not a GVP device, I'm assuming that gvpscsi.device wouldn't be the driver to use.
