The seagate driver does not like anything to be at address 6 when it is
running on a future domain controller. I've successfully run things from ID 0.
I must admit that I've never had the chance to test it's handling of LUNs, and
the controller that I used to have has passed out of my hands. I would advise
getting hold of an old Adaptec 1542 or Buslogic controller (or failing that,
one of the supported VLB controllers). The FD maxes out at 1Mb/s, and uses
100% of any CPU at that data transfer rate.
