I've been doing some experimenting with a MBR-7 on my home machine.  I have had
it crash my system, but I'm no longer sure that it's the fault of the jukebox.
I've been able to mount cdroms on LUN's 0 through 3 and had everything work
reliably.  But if I mount and then access any of LUN's 4 through 6, my machine
panic's in seemingly random places.
