1. Make sure each device to be connected to the host adapter is set to a separate SCSI ID. 2. The AHA-1540CF/1542CF is set to ID 7 by default. This can easily be changed with the SCSISelect utility, as described in Section 3.
SCSI bus must have a set of resistors called terminators. All other SCSI devices must have terminators removed/disabled. The AHA-1540CF/1542CF and most SCSI peripher- als come equipped with built-in terminators that can be enabled or disabled. Exactly two devices must be terminated on the SCSI bus, one at each end.
Adaptec’s DOS I/O Operating Envi- ronment Software, or via the BBS. See Section 6. Make sure sw5 on the AHA-1540CF is in the On/Closed position. It must remain in that posi- tion, even though there is no floppy controller on that host adapter.
