I didnt pay enough attention when I first read it - now I can see your concern - It certainly looks like you have 3 where you should have 1 - it should read :
ATA Channel 0
ATA Channel 1
Standard Dual Channel PCI IDE Controller
Try updating your bios and chipset drivers
- I'll check your motherboard site and finish post shortly.
You can get your latest bios update at the Asus site - use the asus live update utility -its easy to use from inside the OS -DOWNLOAD the bios file then open the utility and locate the folder its in using browse. Use the search on the right side to select your board - motherboard -sockect 939 - A8N32-SLI Delux http://support.asus.com/download/dow...Language=en-us
OR GO HERE and select download http://www.asus.com/product.aspx?P_I...specifications
Its damn complicated and hard to figure - go into your bios and see how what sort of drive configuration you have .
Im not sure what to suggest there is limited drivers on the asus site -personally if it isnt causing you any problems I would just leave it - Windows 7 has loaded a driver
for it - there are 3 entries - this seems wrong but if its working just ignore and think your lucky - post back about bios setup - to tell you the truth I have't any experience with these boards and I cant find anything on the nvidia site driver wise for NVIDIA nForce 4 SLI chipset.
The other thing is it says its a PCI controller have you a PCI Card for IDE?
