The trouble is my Mask/MaxTransfer setting is set to Zorro3 hex speeds that can go up to 16mb/s... this concerns me and I'd like to try the settings for the same speed as an IDE drive just for curiosity.
MaxTransfer has nothing to do with transfer speed.
MaxTransfer is the maximum size of the block that can be transmitted in one operation. Larger operations are split into MaxTransfer chunks. 16MB (0xfffe00) MaxTransfer doesn't limit the speed to 16 MB/s.
Typically all SCSI devices should be able to handle 16MB (0xfffe00). IDE devices handle 128K (0x1fe00).
