Re: Bug#927892: grub-ieee1275-bin: Please add bootinfo.txt for sparc and sparc64

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

there is a copy of the -G image file in the ISO:

  /boot/grub/sparc64-ieee1275/cdboot.img

It has only 512 bytes. Very non-zero.

But block 0 is for the SUN disk label (partition table).
libisofs overwrites it completely at ISO production time.
See
  https://sources.debian.org/src/libisofs/1.5.0-1/libisofs/system_area.c/#L776

grub-mkrescue copies stuff to bytes 512 to 767 of its -G image.
Maybe you should prepend 512 0-bytes to your cdboot.img.


Have a nice day :)

Thomas
