NAME
esiop —
Enhanced Symbios Logic/NCR
53c8xx SCSI driver
SYNOPSIS
esiop* at pci? dev ? function ?
options SIOP_SYMLED
scsibus* at esiop?
DESCRIPTION
The
esiop driver provides improved support over
siop(4) for the Symbios Logic/NCR
53x8xx series of SCSI controller chips:
- 53c825 and 53c825a (Fast-Wide
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)
Older adapters are supported by the
siop(4) driver.
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.
