It was mentioned in a past thread that there was a conflict with the Deneb USB card and the Cybervision 643D RTG card. Chris mentioned at that time that work was in progress on an update for the Deneb to work around the bug in the CV643D.
I noticed that the update for the Deneb was on their website so I flashed my card with the new file v9, updated Poseidon to v4.1 and Luciferin. I installed the CV643D card, installed CybergraphX 4 rebooted and then selected a nice big RTG screenmode!
Cheers guys, it works great. Thanks. :-D
Now I can finally screw the lid back on my A4000 as there's no more room to add anything!
One general question for any Deneb users out there. Before the update of the Poseidon software to v4.1 and after I still can't get the USB stack to run on start-up. I have to run Trident, click "restart" to get attached devices regognised, but the "SAVE" button is greyed out. Anyone know how I can save my prefes so the USB stack is running on start-up? I've never had this problem before.
