Official Debian PowerPC install iso images wont boot on my two machines
because IBM OpenFirmware on IBM RS/6000 44P Model 170 and IBM SLOF
firmware on YDL PowerStation are not able to read files from isofs.
Unofficial Debian Install CD created with --iso-level 4 mkisofs option
boots fine on both machines.
Linux on POWER Bootable ISO HOWTO [1] instruction says:

Other linux distributions targeting IBM POWER machines create their
PowerPC install CD images using -U option. The -U option "Allows
'Untranslated" filenames, completely violating the iso9660 standards,"
so it is probably better to go for --iso-level 4 as it produces
ISO-9660:1999 compliant CD/DVD images, and as far as I can see works
fine on Macs and IBM machines.
Could you, please, apply the patch attached to bug report #603536 to
create proper bootable .iso for Power machines, and make sure Squeeze
PowerPC iso images are produced with the same option.
Thanks,
Milan
