OK, the system with the 2010 boots now. It has 1TB of disk
space, 4GB of ram, and is running a bunch of postgresql databases.

One thing...
I had 'link    rasr0   rdpti0' in /etc/devfs.conf 
so that the asr raidutils would work. With your changes,
this no longer works. I no longer have an 'rasr0', but
instead a 'asr0'. If i link this to 'rdpti0', then
raidutil works again.

I've done a bunch of dd to and from disk with success, 
and the postgres' seem to be ok.


The performance is nothing to write home about, about
22MB/s on write (to filesystem from /dev/zero), and 
only about 10MB/s on read (from /dev/da0 to /dev/null).
I don't know how to tell if i'm getting errors or anything
with this driver. I'm not sure what i had before this change,
i'll try and re-run the test.

I have

I tried 'raidutil -e soft -d0' as the raidutil man page suggests,
but it says 'Must specify an address for this command: -e soft '
