You actually make gop calls to perform the IO for you. Grub can leave the display in that state when passing off to the kernel, but the kernel has to have its own KMS video driver to take over; it can't just start poking at a frame buffer like it can with VESA. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJPFEPEAAoJEJrBOlT6nu75SmgIAJq8XvbE8/g/dtwwVOmwLpgW ahFS5MQU1CCvkmXE54GteIfMVmdLxiRgBdlLH8VxXr4CW19YpYyAWtoi+ib038QB b7DeaReDw2WzYrikw7Ezt1mWejw7t4Ysv1eEjw0ppQlLMm+/Rnwf+qum5nddWeIh ognAT03nqcu+AsOv7G++wiSltNLKXfACrjhdr/VRAmibGT1a5/er0z26evGW1U5/ eXWX5kSpsNDuMQILBKvVkLkACK8cC4apKkhATBGA2pGENPgys+fu7NzTJm/j16dt sAuck2a+LpCEJ7os90JwouPVITLeQ05p07LwqJhMMfRkDApoIfgWYXGBFPlTbbE= =EUzD -----END PGP SIGNATURE-----
