.Sh SYNOPSIS

.Cd "ncrsc0 at pcctwo? ipl 2"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver provides an abstraction layer between the SCSI hardware
|
||
|
|
fitted to
|
||
|
|
.Tn Motorola
|
||
|
|
MVME167 and MVME177 single board computers (NCR73C710),
|
||
|
|
and the machine independent SCSI drivers described in
|
||
|
|
.Xr scsibus 4 .
|
||
|
|
.Pp
|
||
|
|
In addition to sending the required SCSI commands to
|
||
|
|
target devices on the SCSI bus, the
|
||
|
|
.Nm
|
||
|
|
driver deals with DMA, device interrupts, sync/async negotiation
|
||
|
|
and target disconnects/reconnects.
|
||
|
|
.Sh DIAGNOSTICS
|
||
|
|
Too many to mention!

|
|
.Xr pcctwo 4
|
||
|
|
.Sh BUGS
|
||
|
|
The current
|
||
|
|
.Nm
|
||
|
|
driver should be obsoleted and replaced with a machine independent
|
||
|
|
version.
