Leave CD/DVD in Xserve drive when case is locked

Hi,
is there a way to leave a CD in the Xserve G5 DP 2,3 when the enclosure is locked. I can unlock it und then put a CD in the drive. When the CD is mounted i can lock the Xserve – the Disc is still accessible and stays in the drive. Good so far.

But when i restart the Xserve the CD will be ejected. I think the OpenFirmware is doing this security job. I have to lock down the server. I am looking for a setting like

LEAVE CD/DVD IN XSERVE DRIVE WHEN ENCLOSURE IS LOCKED.

Maybe there´s a hidden switch in a preference or xml file for this purpose.
Otherwise this is a feature request for apple.

For Keyboard and mouse usuage when case is locked there´s a checkbox in system preference under the security menu.

Kind regards,
Bjoern
