   The other drive is a Quantum 540S. Didn't try it without SMP yet.

   It does work with 8 - however I dont think this excercises the paging
mechanism. (Also I reeaaaly want to use as many as possible ;)))

   Does the driver downgrade the number of SCBs for a specific device
if the current number is too high? Some of the other drivers do this
successfully - it would be a nice idiot-proof feature to implement.
