GA-EP45-UD3R Chipset Installation Question

All,

I am still working on installing and testing components and software on a GA-EP45-UD3R with a Q9550 and 4GB Corsair Dominator RAM and a Radeon 4870 1G and Windows XP Pro. I have been investigating an issue with my CD/DVD burners (a Plextor 708A and a Sony DRU840A) using Nero 9.

I installed Nero and tested and was able to burn data without an issue for a day or two. Then, later when I wanted to burn some rescue CDs (UBCD, Acronis True Image, etc.) I started getting serious errors in the process such as "bad write state", "unable to provide fixation", etc. Most forums typically explain this away as bad media or some equally lame cause (the media I use is fine, trust me).

I finally came across a solution that apparently worked. The drives are connected to the IDE connector which is listed as a JRaid device (GBB36X) and appears under SCSI Controllers. Needless to say, I though this was odd since it's an IDE connector, not a SCSI device. Reinstalling the absolutely latest JRaid driver did nothing to solve the issue. I also noticed that in the Nero logs that the DVD drives did not have DMA enabled and there was no place to enable that for either drive. So something was amiss.

What DID work was to right click on the so-called SCSI controller and CHANGE the driver to "Standard IDE controller" which again detected the drives and suddenly gave me the ability to enable DMA on the drives and the two burners have been happy ever since.

So the question (finally got to that!) is why did this IDE controller get detected as a SCSI controller? I believe this is due to the Gigabyte chipset drivers being installed from CD and not XP determining the wrong device. Shouldn't the motherboard and chipset driver installation routine be better coordinated between each other and select the correct driver?

While this is not extremely critical, it's annoying to say the least. This is more of a rant than a question so if no one has a comment, just ignore this. But if someone has an explanation of what's going on, I'd like to hear it!

Thanks!
