NCRSC(4)

NAME
ncrsc - NCR 53c710 SCSI I/O Processor

SYNOPSIS
ncrsc0 at pcctwo? ipl 2

DESCRIPTION
The ncrsc driver provides an abstraction layer between the SCSI hardware fitted to Motorola MVME167 and MVME177 single board computers (NCR73C710), and the machine independent SCSI drivers described in scsibus(4).

In addition to sending the required SCSI commands to target devices on the SCSI bus, the ncrsc driver deals with DMA, device interrupts, sync/async negotiation and target disconnects/reconnects.

DIAGNOSTICS
Too many to mention.

BUGS
The current ncrsc driver should be obsoleted and replaced with a machine independent version.
