Ah no, that's not correct - BootX is an enhanced bootloader written by Apple to enable multi-booting with MacOS X and grub-mkrescue is assuming that it is being installed on a HD containing MacOS X with BootX in the default location. Whilst this makes sense assuming that you are trying to fix booting a MacOS X partition in a multi-boot setup, this certainly isn't the case for an installer CD. And certainly this confuses things because in real life BootX is a COFF executable and not a bootinfo file. In my travels with qemu-system-ppc, most CDs I've seen use the CHRP convention of \ppc\bootinfo.txt and then bless the \ppc folder so then no matter whether you are using a Mac or other CHRP-compliant machine, everything boots the same way. ATB, Mark.
