CHRP is marked by an MBR partition entry of type 0x96 spanning the whole
ISO 9660 image.
@ -966,12 +967,16 @@ ISO 9660 image.
The specs in chrp1_7a.pdf promise that CHRP also recognizes ISO 9660 file
systems on unpartitioned disks. (See 11.1.1. Media Layout Format)
The firmware looks up a file /ppc/bootinfo.txt which in SGML-ish tag
<boot-script> contains firmware commands.
E.g. to execute the binary /boot/grub/powerpc.elf as first stage of GRUB2:
<boot-script>boot &device;:\boot\grub\powerpc.elf</boot-script>
Vladimir Serbinenko stated:
PReP boot may be preferable. At least it can co-exist with other partitions
in the ISO image [without causing overlapping between partitions].
