The AHA-1542CF has built-in termination, controlled by one of the DIP
switches or by a BIOS option (if you set the switch one way, the BIOS is
disabled). If you turn on the card's terminator, then you should have
either only internal or only external devices, and the end of the chain
should be terrminated. Both ends of the SCSI bus should always be
terminated; this way the host adapter happens to be at one end.
