It is an Issue D board that I have here that doesn't appear to work at
the moment. Just hangs trying to mount the disk when ADFS starts. With
the other host adapter it is fine. Is there anything inparticular to
look out for with these Issue D boards? All terminators are present.

I did do some extensive testing of SCSI drives on these host adapters
but always came across some sort of timing problem - probably as
mentioned due to the lack of the ATN line as suggested. These were all
old SCSI I & II type drives.
