          NAME
               tmc8x0 - low-level controller module

          DESCRIPTION
               The tmc8x0 module provides low-level interface routines
               between the High Performance Disk Driver (see hpdd(7)) and
               the Future Domain TMC-830 and TMC-841 Intelligent Small Com-
               puter System Interface (SCSI) Host Adapters.  It can be con-
               figured for disk or streaming tape support for one or more
               host adapter boards, each of which must be the sole initia-
               tor on a SCSI bus.  The low-level code determines if the
               adapter is, in fact, present at the configured address (see
               disk(7) and tape(7)) and what types of devices are attached
               to it.  It handles simultaneous requests for all devices,
               overlapping operations where the devices will permit.

               For information on configuring a kernel to include the
               tmc8x0 module, refer to the ``INTERACTIVE UNIX Operating
               System Maintenance Procedures.''

             Board Configuration
               The default configuration described in your Future Domain
               TMC-830 and TMC-841 user's manual should be used for stan-
               dard configurations of the system.  If more than one board
               is to be used in a single system, each must at least occupy
               a different set of I/O address ranges and use a different
               DMA channel.  Use of a different interrupt level for each
               board is encouraged, although not required.
