ipx7a mcp79 gsa-t40n no cd during insallation

[Emilianio]

Hi,

my dvdrom LG hl-dt-st GSA-T40N is not recognized during installation (motherboard prestigio ion nvidia mcp79 chipset). The last version that I was able to install using cdrom was 8.04 with boot option all_generic_ide. The cdrom works slowly!, but there was no driver for the graphic chipset (nv9400) for this old kernel version (nvidia 185 needed). So I updated to newer version.
I tried 8.10, 9.04, 9.10, alternate cd, dvd, burning with slow speed, changing the sata cable, changing the bios settings (sata ->ahci), boot options like all_generic_ide, ... everything that I found and all the combination. gsa-t40n still not working

The actual status is:

ready but no cd or dvd is working, not even simple audio, can't read contents on it, can't mount.

uname
Linux desktop 2.6.31-20-generic

I updated to 9.10 using network (from 8.04), everything is working perfect (nvidia 185 graphic driver is fine, full HD ok), but the cdrom. The cdrom is working with microsoft vista (installed and removed), so it is probably not a hardware problem. I also tried pre-release 10.04 , and 2.6.32 in 9.10, no change. The computer is: prestigio ion ipx7a nv9400 mcp79

if there is some way to install some driver, patch, enable modules or so, please help me to find it
Why is the only one capability of the cdrom: audio ?

Thanks for your time
