        !             3: cyc \- Cyclone fiber interface
        !             4: .SH SYNOPSIS
        !             5: .B bind #C /dev
        !             6: .PP
        !             7: .B /dev/cyc
        !             8: .SH DESCRIPTION
        !             9: The
        !            10: .I cyc
        !            11: device drives the Cyclone CVME961
        !            12: .RI ( not
        !            13: 960)
        !            14: card with an attached
        !            15: SQFBR Squall module
        !            16: to provide a high-speed point-to-point 9P link between a CPU
        !            17: server and a file server.
        !            18: Both machines must of course have VME buses.
        !            19: For debugging,
        !            20: the Cyclone may be loaded with on-board
        !            21: software using
        !            22: .B xms
        !            23: (see
        !            24: .IR con (1))
        !            25: and the NINDY ROM supplied with the device.
        !            26: In production, though, it is easiest to
        !            27: replace the ROM with the program in the directory
        !            28: .BR /sys/src/fs/cyc .
        !            29: In either case, the on-board software expects an identical
        !            30: Cyclone to be at the other end of the fiber.
        !            31: One of the boards must be in a CPU server, the other in a
        !            32: file server; the systems configure their respective
        !            33: boards dynamically as appropriate.
        !            34: .PP
        !            35: The driver serves a single file,
        !            36: .BR /dev/cyc .
        !            37: When opened, the file initializes the connection to the file
        !            38: server.  The resulting file descriptor should be used only
        !            39: to send and receive 9P messages.
        !            40: Typically
        !            41: .IR boot (8)
        !            42: will open
        !            43: .BR /dev/cyc ,
        !            44: prime the connection by sending
        !            45: .B nop
        !            46: and
        !            47: .B session
        !            48: messages (see
        !            49: .IR attach (5)),
        !            50: and then
        !            51: .B mount
        !            52: (see
        !            53: .IR bind (2))
        !            54: the file descriptor in the CPU server's name space.
        !            55: Thenceforth all activity on
        !            56: .B /dev/cyc
        !            57: will be mediated by the mount driver
        !            58: .IR mnt (3)).

        !            74: The driver is specific to the SGI Power Series, although the device
        !            75: should operate on any VME bus.
