NAME

mcst − low-level controller module

DESCRIPTION

The mcst module provides low-level interface routines between the High Performance Device Driver (see hpdd(7)) and controllers using an IBM/ST506 interface in a Micro Channel-compatible machine.  The driver can be configured for disk support for one or two controller boards if the machine supports a multiple ST506 controller configuration. However, it can be configured to run with other non-ST506 controller boards.  The low-level code determines if the controller is, in fact, present at the configured address (see disk(7) and tape(7)) and what devices are attached to it.

For information on configuring a kernel to include the mcst module, refer to the “INTERACTIVE UNIX Operating System Maintenance Procedures.”

Board Configuration

The reference diskette that accompanies the Micro Channel machine should be used for standard configurations of the machine.  If a machine is configured with an IBM/ST506 and an IBM/ESDI (see mcesdi(7)) interface controller, both controllers must share the same interrupt level.
