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: https://lists.freebsd.org/pipermail/freebsd-questions/2017-September/278783.html 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 .. Happy hunting, cheers, Ian PS Warren: I appreciate the efforts you've already put into this.
