I have never got it to work with a fat filesystem. I have tried on a p710 and a p520. Maybe it worked on older ones. > Yaboot installer installs yaboot on IBM Power machines exactly the same way. > > This will not make life harder nor easier for IBM users.

Well it looks like it will if you happen to create the /boot/grub partition, except it won't work that way. So the error message will tell you to do something that won't work. > Thank you for providing information about your experience with grub on > IBM Power machines.

I will certainly try to help test it at that time. The way I am using it is what grub-install expects on IBM powerpc at this time. I would love to see a working example where you use FAT on an IBM powerpc, because I haven't found any reference to it in any of the documentation or anywhere else, and it has never worked when I tried it. The openfirmware syntax where you specify a file on a filesystem simply never worked on either machine I have here. Seems to work fine on Macs though. I will look up the bootinfo.txt though. Maybe that will provide some hints. Could make grub simpler to work with. -- Len Sorensen -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
