However elilo-3.x 13 | requires at least gnu-efi-3.0. EFI support for x86_64 is provided in 14 | gnu-efi-3.0d. 15 | 16 | Both packages can be downloaded from: 17 | 18 | http://www.sf.net/projects/gnu-efi 19 | http://www.sf.net/projects/elilo 20 | -------------------------------------------------------------------------------- /README.git: -------------------------------------------------------------------------------- 1 | README.git 2 | 3 | Generating releases from git a very simple process; 4 | 5 | 1) Edit the file "Makefile". Changing the "VERSION" line to the new version. 6 | 2) Do a "git commit" just for the version number change. 7 | 3) Then do a "make test-archive". 8 | That will make a file in the current directory gnu-efi-$VERSION.tar.bz2 , 9 | with its top level directory gnu-efi-$VERSION/ and the source tree under that. 10 | 11 | Once you've tested that and you're sure it's what you want to release, 12 | 4) Do "make archive", which will tag a release in git and generate a 13 | final tarball from it. 14 | 15 | You then push to the archive, being sure to include the tag: 16 | 5) "git push origin master:master --tags" 17 | 18 | And upload the archive wherever it's supposed to go. 19 | 20 | 21 | 22 | -------------------------------------------------------------------------------- /apps/bltgrid.c: -------------------------------------------------------------------------------- 1 | #include 2 | #include 3 | 4 | extern EFI_GUID GraphicsOutputProtocol;
