And as far as I can tell, entirely undocumented - though looking at the
commit messages for the file mentioned below might be helpful; I gave up
before trying. As mentioned, I'd grep'd source of mans for loader.conf
and pretty much everything else to do with booting and loader; not to
say I didn't miss something obvious to someone who actually knows this.
Sorry about breaking threading by (albeit carefully) replying to the
digests, but to not waste the quite some time put into hunting this:
That is, check /usr/src/sys/boot/efi/loader/arch/amd64/framebuffer.c
So if this file appears in 11.1 - or 10.3? - then maybe somebody can
figure out what parameters might be fed to gop(0) and to what effect;
reading the whole code sort-of seems to offer some sort-of clues ..
PS Warren: I appreciate the efforts you've already put into this.
