I have an LG GCE-8523B 52x24x52x CD-rw, and I upgraded my computer few days ago, and now i have an MSI Nforce2 motherboard. (I had an Chess VIA Chipset board before this and didnt have htis problem at all)
The problem is, my CD-RW insists on working in PI0 mode. Anyways, I read few threads on this forum about this DMA problems, and tired all, but none solved my problem. I have my CD-RW Connected as IDE2 - Master, and DVD-Rom (also an LG) connected as IDE2 - Slave. I also tried playing with the IDE and all (like connecting CD-RW alone, and connecting as slave etc.) but nothing worked and my CD-Rw is still working on PI0 mode, which is very annoying as you know.
My Nforce2 drivers are up-to-date, and i tried the firmware for LG-CD-rw, but it doesnt seem to work either... Like i said i also tried few other methods explained in these forums, about the DMA problem, but its still PI0...
So if anyone knows the answer, please help me because i really hate using this CD burner on PI0 mode.
