Hi Marc, As far as I know, changing to ahci is always done in "SATA options" of BIOS, I have found it does work at least in 4 machines of mine, including one very old machine dell D630.
If you google "Sata ahci ide", you will find sata controller should support ahci. I don't know why BIOS of this machine doesn't provide the option of AHCI, could you query Dell guys about how to change to AHCI? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/794642 Title: [Dell optiplex 390][SFF] Dvd drive not recognized by system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/794642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
