I did as you asked. You can see the result at: https://owncloud.towernet.ca/s/6K3pGknCyGTi7du ... but the long and short of it is that even though the loader is printing in the center of the screen (text mode?), it sees the 1920x1080 mode as the "mode 0" ... I even tried "gop set 0" ... which it accepted, but then continuing to boot produced what you see in the video. I think, since it's in the cetner of the screen, that we're looking at 80x25 text... which is ... 800 x 600 -ish? The kernel definately wants graphics again ... but ... I dunno ... is it getting it? Is the 80x25 text mode emulated on a bitmapped screen?
