SIOP(4)                      Device Drivers Manual                     SIOP(4)

NAME
     siop - Symbios Logic/NCR 53c8xx SCSI driver

SYNOPSIS
   hppa
     siop* at mainbus? irq 3
     siop* at phatomas? irq 3

   PCI
     siop* at pci? dev ? function ?

     options SIOP_SYMLED
     scsibus* at siop?

DESCRIPTION
     The siop driver provides support for the Symbios Logic/NCR 53x8xx series
     of SCSI controller chips:

           -   53c810, 53c810a and 53c815 (Fast SCSI)
           -   53c820, 53c825 and 53c825a (Fast-Wide SCSI)
           -   53c860 (Ultra SCSI)
           -   53c875 and 53c875j (Ultra-Wide SCSI)
           -   53c876 (Dual Ultra-Wide SCSI)
           -   53c885 (Ultra-Wide SCSI and Ethernet)
           -   53c895 (Ultra2-Wide SCSI)
           -   53c896 (PCI 64bit, dual Ultra2-Wide SCSI)
           -   53c1010-33 (PCI 64bit, dual Ultra160 SCSI)
           -   53c1510d (PCI 64bit, dual Ultra2-wide SCSI)
     The SIOP_SYMLED option causes the driver to report SCSI activity on the
     GPIO pin 1, which is connected to the activity LED on some adapters.  At
     this time only the 53c895 based Symbios and Tekram adapters are known to
     require this.

     If both siop and the esiop(4) drivers are compiled, esiop(4) will take
     precedence for controllers it supports.

HISTORY
     The siop driver first appeared in NetBSD 1.5.

AUTHORS
     The siop driver was written by Manuel Bouyer <Manuel.Bouyer@lip6.fr> for
     NetBSD.

BUGS
     siop supports the 53c1010-33 in Ultra2-wide mode only.  Use esiop(4) for
     Ultra160 support.
