Hello,
I trying to cobble together a simple Hello World ``kernel'' on the
mac, and have a question concerning the booting specifics. I
understand that OF 3.0 groks ELF, but the ELF file should contain
some special information in the note sectio
if at all?
Thanks again for the information and have a great day.

CLAIM it again. Is there some way of convincing OF to
free up the memory it just gobbled up, after my kernel had exited?
Thanks again.

Can OpenBoot directly boot ELF or COFF images? I looked at SILO and
it seems it uses a 512-byte boot block to load second stage etc.

Hello,
I would suggest building a bootstrap gcc powerpc crosscompiler and
binutils, where the the host is your OS X system and the target is
powerpc-linux. This will allow you to build PowerPC ELF objects,
which you can then boot with OF. It is my understanding that the
GRUB2 PowerPC buil

had no issues. My understanding is that you will have to somehow
convince the GRUB2 build to use your gcc versus the system one.
Have a good day.

I think the best solution would be to entirely avoid Apple's bundled
OS X-specific GCC. An powerpc-elf -targetted GCC cross-compiler
hosted on OS X should be perfect for both OpenSolaris and for GRUB2.

There is another issue with GRUB2 on OS X which I am not sure has
been brought up yet.
Right now, AFAIK (but I haven't tested it), GRUB2 (the part that runs
from OpenFrimware) can be built
with a bootstrap powerpc-elf-targetted GCC hosted on OS X. However,

Hmm, I just tried ./configure-ing.I have my powerpc-linux crosscompiler tools as powerpc-linux-{gcc, ld, ar, objcopy, etc}. It seems the configuration utility makes no distinction between compiler toolchain to make system utilities and compiler chain to make bootable executables.Naturally, this bei

GRUB2 is to be used on the Mac OS X operating system, the tools
need to be Mach-O based.

Aside from compiling/linking issues, there is another thing to keep
in mind should there ever be a port of bootable GRUB2 parts to OF/
Mach-O. OS X uses a different calling convention, so any assembly
bits would have to be properly adjusted.
I still think the best solution here would be to c
Hello,
I really don't know who else to approach with this, and this is
(potentially) GRUB 2 related (if/when GRUB2 boots from CD). Basically

10.4), and decided to look into making a bootable CD so I could use

Take anything I say with a grain of salt, but...
AFA I understand, if the disk is an HFS or hybrid HFS/ISO,
OpenFirmware scans it for a "blessed" folder, and looks for a file
with a resource type "tbxi", which it then runs. This is usually
(always?) a bootinfo script that specifies further
