DESCRIPTION    [Toc]    [Back]

     The siop driver provides support for  following  LSI/Symbios
Logic/NCR
     53c8xx and related 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 and 53c895a (Ultra2-Wide SCSI)
           -   53c896 (PCI 64bit, dual Ultra2-Wide SCSI)
           -    53c1010 (PCI 64bit, dual Ultra3-Wide SCSI.  NOTE:
at this time
               siop supports at most Ultra2-Wide with this chip)
           -   53c1510D (dual Ultra2-Wide SCSI)

     siop replaces the older ncr driver which supported  most  of
these devices.

     Older  53C700  and  53C710  controllers are supported by the
oosiop(4) and
     osiop(4) drivers, respectively.
