ISP(4)                    NetBSD Programmer's Manual                    ISP(4)


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 dis-
     able the download of driver f/w, which means you use whatever F/W is run-
     ning 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.
