I have got a A1200 PPC+Bvision, but when I disconnect my hd and boot up from DF0 then I only have AGA output and nothing from the Bvision. Of course not, there´s nothing installed on the Workbench disc to use a gfx card, and even if it would be installed then the screenmode is standard set on the original video-output and not to a gfx card ... makes sense, doesn´t it ?
