I hadn't considered that, but your reply makes me very glad I didn't
try! The funny thing is that I would have had it not been for the
networking issues I mentioned, so unless the BIOS setup mentioned that
even JBOD single disks would be erased (which it probably does, to
HighPoint's credit) I would've gotten my largest MythTV-recording
array into big trouble.

This, I didn't know; I know 3Ware and Areca make real hardware-RAID
cards but thought HighPoint's higher-end gear was also not
fakeraid. In any case, as you saw, I have never been interested in the
2240's built-in RAID functionality, whatever its provence.

sata_mv is definitely a module; as mentioned, I was able to rmmod it
after stopping the RAID array. Does initrd contain discrete modules
that can be unloaded? I'd though it was just the monolithic-kernel
