My 0.02 cents:
	I did not installed FreeBSd on a DPT controller, but with an
Adaptec controller.  Nevertheless, I have a DPT controller on a system
with a large fs (71780140 1K blocks).  The system works, works well and
has been up for 4 days as a very busy usenet news spool directory.
	This is running 2.2-RELENG from last sunday.

As a sidebar; the DOS configuration software can only create arrays with
up to 1 mbyte interleave.  Is this a limitation on the hardware or the
software ?  Is (will there be) a way to create an array with a larger
interleave (32 megs comes to mind).

	Thanks, Simon, for a job well done.
