yaboot troubles on dual boot machine

boojummy

Hello,

I recently installed a security patch on the OSX (10.2.8) side of my dual-boot OSX/Gentoo box. When I rebooted the machine, it automatically booted into MacOS, even though my yaboot.conf specified booting into Gentoo.

No problem, I thought, I'll just boot off of the LiveCD, chroot, and run ybin again. No luck. Apparently the changes don't take (I've tried this about 5 or 6 times, even futzing with manually specifying everything to ybin/mkofboot). It still just boots into OSX.

I've since discovered that I *can* boot into Gentoo if I drop into Open Firmware and manually specify my bootstrap partition, like so:

Here's a link to a thread where other people are discussing this problem. It seems to be related to the fact that the 10.2.8 update changes the system's firmware.

i have had this problem on multiple occasions (when i upgrade the osx system, security patches etc.)

first yes, switch the bootstrap to /dev/hda2

not hard, just:
mac-fdisk /dev/hda
r
10
2
(i think, not in gentoo right now, but a quick man mac-fdisk will show exactly)

then, easier than openfirmware is to hold the "alt/option" key down as it boots up, this shows you a list of the disks and coresponding systems (similar to the classic "buttons" theme)
it takes a little while to load but then you can click on the one with the little penguin at the bottom and boot into it.

then try again to ybin....

worked for me, multiple times.

for the record, i am running 10.3.3, but i had the problem and this fixed it under 10.2.8

You may also have to update yaboot if not using the current version, there were fixes for this problem in yaboot code at one point as well ...

I just wanted to post back (I didn't have time to do this until now... sick day) about this. killfire's solution (renumbering the partitions) worked perfectly. As a side note, anyone else who tries this should make sure to reboot after reordering the partitions (for the new partition map to take effect), then boot back up with a boot disk and rerun ybin/mkofboot after making the appropriate changes to yaboot.conf (or run yabootconfig). Yaboot fails otherwise.

Thanks for the help!
