A very good starting point would be the RiscBSD FAQ. You can read this
from the RiscBSD Web pages :

http://www.ph.kcl.ac.uk/~amb/riscbsd/

The Web pages are horribly out of date (hint hint...) but the FAQ is
better.

In brief :

* Yes, it works on StrongARM.

* Yes, you can use the SCSI bus.

* No, there is no CD distribution as yet.

* This mailing list is an excellent place to ask questions - even the
obvious ones.

Hope this is of some help.
