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.
