To whom it may concern:
The Section 5.2 - Booting from a CD-ROM command ( located at http://www.debian.org/releases/stable/powerpc/ch-rescue-boot.en.html ) should read the following for people who are trying to boot from CD 1 of the Debian Sarge distribution for MacPPC:
boot cd:,install\yaboot
instead of
boot cd:,install\powerpc\yaboot
The second command resulted in (paraphrased) a failure to load or boot because the file doesn't exist at that location on the CD. If this error has already been noted for the Debian Sarge distribution, then please disregard.
Cheers!
