If you're using the autoconfig stuff with RAIDframe, then the devices can move 
to any address they want, and RAIDframe will glue them together in the correct 
order.

Hard to tell.. what does your /var/run/dmesg.boot say?   (I.e. what type of 
siop do you have, and should it be syncing at something faster than 20.MHz?)
(Hmm.. from the message Feico Dillema posted on July 4, they appear to be 
53c875's, and 20MHz is the norm.)

Hmmm.. what is 'target 6'?
