I will continue with my issues, it has worked for the sound so i hope it will be the same for the CDRO :)
I cannot burn CD/DVD when the CD player is connected to the motherboard because the size avalaible on the device is not recognized. I have always 0.00 mb available ..cannot burn.
On the other hand if i cannot the player on my additionnal PCI sata card it works.
So it is a work around, but each time i need to boot on the cdrom i need to change the sata connexion and for me it is not really good for the hardware
