LSI/Symbios Logic/NCR 53c8xx SCSI
interface
SYNOPSIS
siop* at pci?
# hppa
siop* at mainbus? irq 3
siop* at phantomas? irq 3
siop* at uturn? irq 3
DESCRIPTION
The siop driver provides support for
following LSI/Symbios Logic/NCR 53c8xx and related SCSI controller
chips:
- 53c720 and 53c770 (Fast-Wide SCSI)
- 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
siopsupports 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.
