Marc, Thanks for your test.
As we discussed in Dublin, the SATA works at IDE compatible mode now, but it is a sata controller and should wok at ahci mode as reported in LP 737388. So I suggested that you can try to upgrade the BIOS to see if newer version can support to change to AHCI mode. Another thing, I would like to figure out how to support IDE mode if you are sure that upstream kernel(such as 3.0-rc5) can support the DVD drive. thanks, -- 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
