NAME

     isp -- Qlogic based SCSI and 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 SCSI or FibreChannel devices.

     SCSI features include support for Ultra SCSI and wide mode transactions
     for SCSI, and LVD (for the ISP1080 and ISP1280),

     Fibre Channel support uses FCP SCSI profile for FibreChannel.  and uses
     Class 3 connections only.  Support is available for Public and Private
     loops.  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 firmware, which means you use whatever
     firmware is running on the card.  If no firmware is running on the card,
     the driver cannot operate the card.

     An optional flags 0x40 appended to the above isp* declarations (can be
     OR'd in with the other config flags option) will keep the driver from
     looking at device or bus NVRAM settings (this is in case NVRAM is just
     wrong and you have the card in a platform where it is inconvenient to
     change NVRAM settings on the card).

AUTHORS

     The isp driver was written by Matthew Jacob for NASA/Ames Research Cen-
     ter.


BUGS

     The driver currently ignores some NVRAM settings.

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

     Sometimes, when booting, the driver gets stuck waiting for the Fibre
     Channel firmware to tell it that the loop port database is ready.  In
     this case you'll see an announcement that the loop state has a value of
     0x1.  To unwedge the system, unplug and replug the fibre channel connec-
     tion, or otherwise cause a LIP (Loop Initialization Primitive sequence) -
     this will kick the firmware into getting unstuck.
