OSIOP(4)		  OpenBSD Programmer's Manual		      OSIOP(4)

NAME
     osiop - Symbios/NCR 53C710 SCSI driver

SYNOPSIS
     osiop* at gsc? irq 9		    (hppa)
     osiop0 at mc0 offset 0x47000 ipl 2	    (mvme68k)
     osiop0 at pcctwo0 offset 0x47000 ipl 2 (mvme68k/mvme88k)
     scsibus* at osiop?

DESCRIPTION
     The osiop driver provides support for the Symbios/NCR 53C710 SCSI
     controller chip.

     The Symbios/NCR 53C700 SCSI controller is handled by the oosiop(4)
     driver, while the Symbios/NCR 53C8xx PCI SCSI host adapters are handled
     by the siop(4) driver.

CONFIGURATION
     The osiop driver supports the following flags for use in config(8) files:

     bits 0-7:	 disable disconnect/reselect for the corresponding SCSI target
     bits 8-15:	 disable synchronous negotiation for SCSI target
     bits 16:	 disable DMA interrupts

     "Target" is synonymous with SCSI ID number.

     Note that SCSI tape drives should be allowed to perform
     disconnect/reselect or performance will suffer.

HISTORY
     The osiop driver first appeared in NetBSD 1.6.

     The original NCR 53C710 driver appeared in NetBSD 1.0 amiga port, and
     Izumi Tsutsui <tsutsui@ceres.dti.ne.jp> modified the driver and made it
     machine-independent.
