NAME
isp - Qlogic based SCSI or FibreChannel SCSI Host Adapters

SYNOPSIS
isp* at pci? dev? function? (PCI)
isp* at sbus? slot ? offset ? (SBus)
scsibus* at isp?

DESCRIPTION
This driver provides access to a SCSI bus or a FibreChannel connected to Qlogic ISP1000 (SBus), ISP1020 (PCI), ISP1040(PCI), ISP1080(PCI), SCSI host adapters or ISP2100(PCI) FibreChannel host adapters.

Features include support for UltraSCSI and wide mode transactions for SCSI, and LVD (for the ISP1080), and the FCP SCSI profile for FibreChannel. Command tagging is supported for all (in fact, FibreChannel requires tagging).

CONFIGURATION
An optional flags 0x80 appended to the above isp* declarations will disable the download of driver f/w, which means you use whatever F/W is running on the card. If no firmware is running on the card, you will lose.

BUGS
The driver currently ignores some NVRAM settings.

The driver currently doesn't do error recovery for timed out commands very gracefully.

Fabric Support (for FibreChannel) is not supported yet.
