how to eject a DVD from a MacBook? On an older Macbook from 2008 the DVD is stuck in the tray.  Unfortunately, GRUB isn't booting properly so there's no OS.

How can I eject the disk?  It's a slot loaded disk, so no button or tray.
ok, there's an eject button:



I held that down at boot.  Still get the grub error, but at least the DVD's ejected.
