I have seen the pictures for both Ultra66 and FastTrack66 controllers, and
they look exactly the same.

I have seen the manual for the UDMA/66 RAID board (Promise FastTrack 66),
and it has a "bios" that you can enter while booting, where you can create
the arrays, select the RAID mode, and fix problems. When I saw this I
thought that the array would be done at the host controller level. Did the
UDMA/33 RAID board have this?
I really would like to have RAID-0, can I do that with the regular UDMA/66
board from promise (Promise Ultra 66) and do the RAID-0 from software
available in Linux? I would prefer using a good controller that does the
array itself, I think it would be faster. Please correct me if I'm wrong.
Thanks in advance for your help,
