Hi all,

I've installed Linux on a PowerBook with a MacOS X dual-boot. All was right, but i decide to upgrade some MacOS X software through 'system update'. When I reboot, my laptop don't ask me how to boot (linux, mosx, cd, of...) and direct boot under MacOS X. I know the configuration of yaboot is very important and may crash your OSes on misconfiguration. So : what's the simple way to restore my bootloader without loosing my 2 favorites OSes ?

Thanks,

Bruno.

Happened to me too. Sometimes, when you update OS-X it overrides the system settings, and basically yaboot get's kicked out of the boot ram. Just boot from your Gentoo cd, mount to your installed system, chroot and re-install yaboot.

also -if my memory serves me right - you can get away by zapping the PRAM:

either while booting in OpenFirmware by pressing Command+Option+O+F just after the start-up chime:

Code:
>reset-nvram [enter]
>shut-down [enter]


or by key-strikin: Command+Option+P+R just after the start-up chime

Well, resetting it will remove yaboot from it. But you can boot yaboot from there, if you want to. You should dig around the forum a little, there were some postings on it sometime last year, when I screwed up my settings ;-)
