The PX-755SA is very similar to the 712SA, so I'm guessing that the 755 
won't work either. I would have guessed that OpenBSD supported SATA DVD 
drives, but the "Platforms" page suggests support is very limited - I 
guess that squelches plans for a SATA HDD as well :( 

Too bad... the SATA drives are a lot faster & relieve cable clutter.
