Just gave this a try (running both those commands) and I'm afraid the behaviour is still identical to what I described previously. I mean, holding down alt is not so bad honestly, and that seems to "just work" with the standard grub install as far as I am aware. > Adrian > > > [1] > > https://salsa.debian.org/installer-team/grub-installer/-/blob/master/grub-installer?ref_type=heads#L1061 > > -- > .''`.

I'm not 100% sure I understand what your problem is, can you elaborate this again? I think you should also better create a new mailing list thread for that since this seems to be a different problem. Normally the firmware should detect and show all blessed bootloaders both in the startup boot menu in the firmware and the startup selection of OSX. The current default bootloader selection is stored in NVRAM separately. In the past, we hard-wired the Open-Firmware path into NVRAM before I understood what is actually necessary for a bootloader to be displayed and selectable in the startup menu which are the two hattrib changes to bless a folder. Every bootloader that has been blessed will automatically show up in the startup screen and will be selectable. But, again, please create a new thread for this and describe your problem in detail, hijacking other threads often just results in such discussions being buried. Adrian -- .''`.

Booting OS X from grub
Hi all, Picking up from the other thread... this is about booting OS X on apple ppc hardware when grub is being used to boot Linux. I tried the version of the BootX file Ben Westover shared in this message https://lists.debian.org/debian-powerpc/2023/06/msg8.html I placed the file in /boot/grub/System/Library/CoreServices/BootX. I then blessed it: umount /dev/sda2 hmount /dev/sda2 hattrib -c UNIX -t tbxi :System:Library:CoreServices:BootX hattrib -b :System:Library:CoreServices humount What I expected to happen, was that on power on I would get a menu, the same as yaboot used to have, which says something like "press l for linux, x for mac os, c for cdrom". What actually happens is that on power on it goes straight to grub, as it did before. If I hold alt down at power on and select the debian option, then I do get the "press l for linux, x for mac os, c for cdrom" menu. However I am not really sure this is worth pursuing, because holding down alt to select the operating system is already a working solution for booting mac os x when grub is used as the bootloader for Linux. I do wonder though how one would go about changing the default boot OS. Thanks, Ed

Ah, that's a completely different problem then. I don't actually know whether GRUB can load other bootloaders when using Open Firmware (ieee1275). This is probably something that needs to be asked on the grub-devel mailing list. Adrian -- .''`.

Am I missing something? I played a bit more (without changing anything). The behaviour I get now is: If I just turn on the machine, it goes to the grub menu. If I hold down alt, I can choose between debian (with a nice logo but called "untitled"), Leopard and Tiger -> OS X options both work -> If I choose debian, I get a menu the same as the old yaboot first menu: Press l for Linux, x for mac os, c for cdrom -> x does boot mac os -> l takes me to the grub menu Thanks, Ed > > Thanks, > Ed > > > > > -- > > Ben Westover
