I was searching on eBay for a Mac G4 (G5 is definitively better but more expensive .. except if you want to make me a donation .. ;-) ) because i wanted to play a little bit with Linux on the PowerPC archictecture. Surely because CentOS 5.1 ppc is in the pipeline (when 5.1 i386 and x86_64 will be released of course ...) and that i want to be able to test it .. and surely also because i have from time to time to setup RHEL on bigger IBM ppc64 based machines (aka IBM system I) . In the meantime i decided to setup Fedora Core 6 PPC (yes, i had a ppc tree on one of my disks ....) on a G4 400Mghz with 512Mb . Everything ran smoothly .. until the machine had to reboot .. and then nothing ... I was almost sure that i had added a Applebootstrap partition during the anaconda setup ... but nothing.
I forget to say that i was installing on another (and bigger) ide drive than the one originally in the machine. And that was my (stupid) problem. I had of course first to boot in rescue mode, use parted to put a mac label on the drive (it had the msdos label since it was coming from an intel box) and then i partition my drive again .. of course this time Fedora installed succesfully .. and rebooted :-)
But what i found strange is that anaconda let me partition the drive as i wanted , formated the drive, installed all the packages and didn't complaint about the drive not having the correct label ... something to write down on the centos wiki when 5.1 ppc will be ready ...
