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.

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.
