mhhh... never tryed that card sorry.
But if you can see the CGX bootlogo:
"When I first installed Cybergraphx (from my v4 CD-ROM) it worked fine. I think after installing the BoingBag updates it now hangs at the Cybergraphx boot picture.
If I remove the Cybervision64 monitor driver from my DEVS:Monitors drawer I can boot into regular OS NTSC screenmodes."
the problem "seems" at the LoadWB stage.
No clue really.
Edit- have you had innstalled Picasso96 before?
