If anyone has set up FC4t2 successfully to multiboot with Mac OS X,
You should be able to just edit yaboot.conf as appropriate afterwards -
Aha, knowing to look at /etc/yaboot.conf is the essential key that was not mentioned anywhere. I suggest that the existence of an hfs+ partition should cause the "macosx=/dev/hdaX" and "brokenmacosx" lines to be added to yaboot.conf, just like the existence of a bootable FAT partition on x86 causes an "other; chainloader +1" entry in grub.conf. Oh, and change the "delay=5" to "delay=15" for multibooting Fedora Core and MacOS X. Many DDC monitors cannot wakeup from DPMS sleep and come to full brightness in 5 seconds, which means that the multibooting choice will be missed. [I'll make sure bugzilla sees this.] --
