[mythtv-users] [OT] CD stuck in Mac Mini

[Rich Wilson]

This isn't strictly a mythtv question, but it's a mythtv howto
that got me into trouble, so I thought I'd start here first.
In following the instructions at
http://mythtv.org/wiki/index.php/Installing_MythTV_on_an_Intel_Mac_Mini_using_Ubuntu
I have repartitioned the hard drive of my mac mini, so there is no
operating system left.
The instructions glibly tell you to reboot with an Ubuntu CD,
but don't tell you how to get the Mac OS Install CD out of the drive.
Anyone know how to do this?

What I've tried:
Holding down F12 on the keyboard for several seconds
Rebooting while...
Holding down the left mouse button
Holding down the right mouse button
Holding down an Alt key
Holding down Windows-Alt-O-F all at the same time

(the keyboard is connected through a KVM, might that be a
problem? I tried connecting a USB mouse directly)

Help!
