Hm, you don't say whether you have terminators on your SCSI busses.

Oh dear ;-( Here's the helptext for Zalon:

config SCSI_ZALON
        tristate "Zalon SCSI support"
        depends on GSC && SCSI
        help
          The Zalon is a GSC/HSC bus interface chip that sits between the
          PA-RISC processor and the NCR 53c720 SCSI controller on C100,
          C110, J200, J210 and some D, K & R-class machines.  It's also
          used on the add-in Bluefish, Barracuda & Shrike SCSI cards.
          Say Y here if you have one of these machines or cards.

I don't really see how I can make this more clear.  Can you tell me which
bit is confusing you?

Use SYM2 -- SYM1 is going away in 2.5, so if SYM2 doesn't work for you,
it needs to be fixed.  We used to need command line arguments on C3k
(and similar) boxes, but we don't any more.
