Yeah, the onboard raid controller is enabled in the bios. I have tried enabling several ways: In raid mode, ide mode and with both drives and single drives. I know that in order to setup an array with 2 drives, they have to be identical, and these are not, but I did try it anyway. No matter what I do nothing shows when connected to the promise raid controller. I read a 'rumor', (someone heard somewhere), that in order to use the promise controller that you have to use 2 identical patas, or 1 sata on master with 1 pata slave. A single pata or 2 unidentical patas wouldn't work. If that's the case, then why do they show in the bios as well as on the boot screen both together and as singles. Both work fine on the secondary ide controller. I do have these jumpered as cable select.
