After upgrading my MacMini and Powerbook to Morphos 3.15 last weekend, I've hit a block updating my G5 Quad.

All the installations and upgrades of Morphos I have done before I have used a USB pen drive and the Open Firmware. However, I have removed the NVidia card from my G5 so to avoid having to re-insert it I have burnt a CDR and then tried to install that way.

The issue I have is that even if I hold C on boot-up, the machine still (eventually) boots from the harddrive and comes up with a message confirming that it hasn't booted from the CD (which is a nice touch by the way).

I've also tried pressing Alt on start-up but I presume that puts me into an early boot-up menu I can't see on the ATI graphics card.

I've tried the CDR on my MacMini and that boots fine with me holding C on boot-up, so its not the media.

As a last resort I will reinstall the nVidia card but I was just wondering if there is a way around this at all?

I might try Openfirmware yet and try typing it blind.
