        That's correct - I believe that card loads a BIOS image, but only
when drives are attached. If I boot with the no drives hanging off that
controller my "normal" IDE drives are hda and hdb, etc. If I hang a drive
on the 66 controller it bumps them all up. Kind of a "no duh" comment - but
the ATA66 drives scream on linux (literally - they make a really cool
noise).
