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.
