.Dd November 28, 1999 .Os .Dt NCRSC 4 mvme68k .Sh NAME .Nm ncrsc .Nd NCR 53c710 SCSI I/O Processor .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 .
p 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! .Sh SEE ALSO .Xr scsibus 4 , .Xr pcctwo 4 .Sh BUGS The current .Nm driver should be obsoleted and replaced with a machine independent version.
