NAME

mcesdi − low-level controller module

DESCRIPTION

The mcesdi module provides low-level interface routines between the High Performance Device Driver (see hpdd(7)) and the controllers using an IBM/ESDI 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 ESDI controller configuration.  However, it can also be configured to run with other non- ESDI 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 mcesdi 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/ESDI and an IBM/ST506 (see mcst(7)) interface controller, both controllers must share the same interrupt level.
