Two possibilities come to mind. 1) The wrong RGB-DOS patch is being 
used. Several are supplied each for a different controller/interface. 2) 
The patch is correct but not correctly applied. 3) The KenTon interface 
does not like the specific SCSI drive that is on your system.

Are you using an SCSI-1 or SCSI-2 drive? What brand/model?
