Yaboot is included with Debian GNU/Linux installation for PowerPC computers.
Updates for Debian may be downloaded via the normal methods, such as
apt-get, dselect, or dpkg. Installation
of an updated version of yaboot on your system does not change
your boot configuration; you must use the included ybin utility to
do that.
You can also download yaboot directly from the yaboot
home page at http://penguinppc.org/bootloaders/yaboot/.
If you download it using MacOS, be sure to download using binary (not
text) format, and don't let Stuffit Expander or another utility expand the
archive in MacOS.
You can download the precompiled yaboot-binary-X.Y.tar.gz, or the
source tarball yaboot-X.Y.tar.gz. To unpack the binary
distribution, use the command tar -zxvpf yaboot-X.Y.tar.gz. The
components are unpacked into a usr/local/ directory inside the
directory where the command was executed.
To make and install from source, first make sure you have a working compiler
(gcc) and the make program installed. (If not,
download the binary yaboot tarball instead of the source.) Then run the
following commands (substitute the actual revision numbers for X and Y):
tar -zxvpf yaboot-X.Y.tar.gz
cd yaboot-X.Y
make
su
make install
