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 | -------------------------------------------------------------------------------- /gnu-efi/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 | -------------------------------------------------------------------------------- /gnu-efi/apps/Makefile: -------------------------------------------------------------------------------- 1 | # 2 | # Copyright (C) 1999-2001 Hewlett-Packard Co. 3 | # Contributed by David Mosberger 4 | # Contributed by Stephane Eranian 5 | # 6 | # All rights reserved. 7 | # 8 | # Redistribution and use in source and binary forms, with or without 9 | # modification, are permitted provided that the following conditions 10 | # are met: 11 | # 12 | # * Redistributions of source code must retain the above copyright 13 | # notice, this list of conditions and the following disclaimer. 14 | # * Redistributions in binary form must reproduce the above 15 | # copyright notice, this list of conditions and the following 16 | # disclaimer in the documentation and/or other materials 17 | # provided with the distribution. 18 | # * Neither the name of Hewlett-Packard Co. nor the names of its 19 | # contributors may be used to endorse or promote products derived 20 | # from this software without specific prior written permission. 21 | # 22 | # THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND 23 | # CONTRIBUTORS "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, 24 | # INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 25 | # MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE 26 | # DISCLAIMED.
