OK i know this information have been posted already in a various places but i couldnt find any normal solution to this.
I got a new computer about a month ago and since i assembled and installed everything i had some nasty hangup problems from time to time. It took me really long time and effort to finally come to the conclusion that this all was cause by the drivers of the opticaldd.
At first when you install the windows the odd shows as one of the primary ide controllers and have UDMA4 enabled for them but after that when i install all the drivers that are needed they drop to the PIO mode.
I have tried various drivers versions, lots of ways of their installation (prior os and after) and they all failed. I even tried this DMA unlocking thing for the registry but it totally ruined everything and they still dropped to PIO. JMicron for some reason has two options of connecting the ide devices the first is the regular ide and the second is the scsi controller. (i have a suspition that scsi actually works better but nowhere close to UDMA4. While in the scsi it is impossible to understand what kind of trasfer the ide has.
So now i am really lost of clues. I left the latest drivers for now and the JM36x at the scsi setting. I am really not happy about all this but now i really dont know what to do.
This is part of the pc spect that is usefull to this post
cpu - Intel 6400
mb - Abit ab9pro
hdd - wd ys 250gb (single hdd on sata1)
odd - sony dvd, lg gsa-h22n (both on jmicron ide1)
here are some posts that i made in other forums that could be useful that atleast made me do lots of wipes of my computer and didnt help at all

http://forum.pcmech.com/showthread.php?t=173877 that helped me understand what was actually my problem
As for simple solutions for this case i would like to ask if
- I should just get another new motherboard?
- maybe i can get a pci-ide device and this will help solving that problem for me?
