Exactly. The rule of the thumb is, if you setup RAID in BIOS, and when
you boot Linux still sees individual drives, you don't have real RAID
controller.
That fake RAID stuff has only one purpuse. To allow users of Windows XP
Home/Professional to have software RAID. If Microsoft shipped software
RAID drivers with Home/Professional (like they do with Server), those
fake RAID controllers would never exist. Or to be more correct, the
controllers would exist (since they are basically just regular SATA
controllers), but you wouldn't see word RAID mentioned anywhere on them,
and there would be no RAID settings in their BIOS.
