Thanks for the reply!
The only thing I could find that was like that was /dev/fd2 which was mounted (?) after the 3 disks were done. I'm guessing that is just the rd they chose to use.. And I tried that, but even though it was mounted, I got the error about no device.
I'll mess around with other rd's and things like that too, see if I can't dig something, anything, up.
Cool
