That brings up a question...what *should* it be?  It was set in the
BIOS to IDE.  As I understand it, to get the most speed/features out
of these drives, it should be set to AHCI, correct?

Also, I've already done a couple OS installs on these drives, so it
would appear changing the setting to AHCI will cause me to reinstall
those OS's.
