Help open DVD drive

[Nordichund]

Hi, does anyone know how to open the DVD drive manually. It won't open if I hold down the mouse button when I turn it on. I had problems trying to install XP in Boot Camp and had to turn off the machine. Now the windows disc is stuck inside that wants to install windows each time I turn it on. It is no good holding down the options key either. Thanks

Managed to do it thanks. The mouse and keyboard seemed completely unresponsive, so I unplugged the usb from the ACD and plugged it directly into the Mac Pro and holding down the mouse button worked
