Once you uncompress the tarball you can go to We have PPCBoot (see the CVS server at SourceForge or ftp://ftp.denx.de/pub/ppcboot) booting on many, many MPC8xx (and MPC82xx and IBM 40x) systems, but this has never been needed to get Linux running (not with any kernel from the 2.2.13, 2.2.14 or 2.4.x series).
