.Sh NAME
.Nm isp
.Nd Qlogic based SCSI or FibreChannel SCSI Host Adapters
.Sh SYNOPSIS
.Cd "isp* at pci? dev ? function ?" Pq PCI
.Cd "isp* at sbus? slot ? offset ?" Pq SBus
.Cd "scsibus* at isp?"
.Sh DESCRIPTION
This driver provides access to a
.Tn SCSI
bus or a
.Tn FibreChannel
connected to
.Tn Qlogic
ISP1000 (SBus), ISP1020 (PCI), ISP1040(PCI), ISP1080(PCI), ISP12160(PCI)
.Tn SCSI
host adapters or ISP2100(PCI), ISP2200(PCI)
.Tn FibreChannel
or ISP2300(PCI) 2-Gigabit
.Tn FibreChannel
host adapters.
.Pp
Features include support for UltraSCSI and wide mode transactions for
.Tn SCSI ,
and Ultra2 LVD (for the ISP1080) and Ultra3 LVD (for the ISP12160)
and the FCP SCSI (private loop, public loop or fabric) for
.Tn FibreChannel .
Command tagging is supported for all (in fact,
.Tn FibreChannel
requires tagging).
.Sh CONFIGURATION
An optional
.Tn option ISP_COMPILE_FW=1
ensures that known good firmware will be downloaded to the driver
at attach time.
This is recommended.
