Appendix A How to obtain and build GRUB

Caution: GRUB requires binutils-2.9.1.0.23 or later because the GNU assembler has been changed so that it can produce real 16bits machine code between 2.9.1 and 2.9.1.0.x. See http://sources.redhat.com/binutils/, to obtain information on how to get the latest version.

GRUB is available from the GNU alpha archive site ftp://ftp.gnu.org/gnu/grub or any of its mirrors. The file will be named grub-version.tar.gz. The current version is 2.12, so the file you should grab is:

ftp://ftp.gnu.org/gnu/grub/grub-2.12.tar.gz

To unbundle GRUB use the instruction:

zcat grub-2.12.tar.gz | tar xvf -

which will create a directory called grub-2.12 with all the sources. You can look at the file INSTALL for detailed instructions on how to build and install GRUB, but you should be able to just do:

cd grub-2.12
./configure
make install

Also, the latest version is available using Git. See http://www.gnu.org/software/grub/grub-download.html for more information.
