I checked the mobo and the scematics in the manual, but I see nothing that looks like a RAID controller. Well, the only RAID controllers that I have ever seen have been on Dell and HP server boxes, so I guess I would'nt know it if I saw it.
The motherboard that you have a link for is a different model, although I can not see any differeneces. My motherboard is not a Platinum. It does have the same RAID controller though; Silicon Image SATARAID5.
When I remove the cables from the IDE controllers, "Detecting Array" no longer appears. On IDE1 I have a CDROM and a DVD Burner (SLAVE & MASTER, no CS). On IDE2 I have a HDD.
What sucks is how SUPER FAST this thing boots up since I finally went to SATA. I just wish I can get the same results with my IDE in tact. Maybe Rolling Rog will come riding in here. Or Johnwill.
