I think if you are using two drives on each channel you'd need to set all
four to cable select?

I have a two-drive Raid-0 setup on ports 3 & 4, attached to the end
connectors on UDMA cables and that's how they're configured -- if I add two
more drives configured the same way they'll be attached to the intermediate
connectors.

The raid controller should then recognise them as a single drive just as it
does the primaries.

I'm also of the opinion that two drives set to master on the same cable
would conflict -- that's what cable select (not recommended for
conventional IDE setups, BTW) is all about.
