| I hope Wesley is still on the list, or maybe another kind soul can help. I saw Wesley's thread in the archives and thought that my problem seemed similar, but the solution as I understand it doesn't. I am a newbie (more or less) that installed Ubuntu (Dapper Flight 3 PPC) on my Power Mac G5, which I can boot into with OpenFirmware. However, I have run into a problem with Yaboot and OS X. Yaboot simply can't load OS X. it tries, and the screen flickers, but nothing happens. After three tries, it says something like "booting Mac OS X..." and nothing works, so I have to do a hard shutdown and then unplug my #1 drive, which is where Ubuntu PPC is installed.. Here is the output from "fdisk -l" /dev/sdb (my OS X system disk): /dev/sdb # type name length base ( size ) system /dev/sdb1 Apple_partition_map Apple 63 @ 1 ( 31.5k) Partition map /dev/sdb2 Apple_Free 262144 @ 64 (128.0M) Free space /dev/sdb3 Apple_HFS Untitled 319910838 @ 262208 (152.5G) HFS /dev/sdb4 Apple_Free 10 @ 320173046 ( 5.0k) Free space Block size=512, Number of Blocks=320173056 DeviceType=0x0, DeviceId=0x0 Here are the contents of my yaboot.conf file ## yaboot.conf generated by the Ubuntu installer ## ## run: "man yaboot.conf" for details.
