Hi all,

I am having problems booting all kinds of linux-CDs on my ibook (also see https://forums.gentoo.org/viewtopic.php?t=117394), but the linux that is installed boots fine (installed as gentoo 1.2 and updated since). I think this problem is related to the firmware version of the ibook. (boot rom version is 4.3.6f3)
The only way I know of to update the firmware is to install a newer version of OSX (currently 10.2.4) so I plan to upgrade to 10.3
My question is: does updating OSX cause the boot proces to be altered, iow will it automatically start OSX instead of yaboot or will I still get the yaboot prompt and be able to boot linux. (I did install a recent kernel (2.6.3-benh2) so that should be able to handle just about any firmware versions it sees after the OSX update.)
If it would automatically boot to OSX then I have a problem since that would require me to boot Gentoo from CD, but that's exactly what isn't working. (And if this problem turns out to be unrelated to the firmware I would be stuck.) The situation is analogous to updating windows on x86. Here windows will overwrite the bootsector. I hope OSX is a bit more tolerant.
Thanks a lot,

Jan.

Yes, installing/updating a Mac OS from a cd or dvd will change the open-firmware boot device to boot OSX automatically. One way around this is to install OSX from within MOL, but I haven't attempted it with Panther.
Anyway, you don't need to boot on a gentoo cd to reset the boot device, you can do it from the open-firmware console (boot while holding Command+Option+O+F). If like me your yaboot partition is the first blessed (bootable) partition on your hd, then just resetting the open-firmware ('reset-all') will make it pick up yaboot on the next boot. If your OSX partition is before yaboot on the hd, then you will probably need to set the boot device accordingly ('set-env boot-device <value>').

Anyway, there's a livecd from the end of October on the gentoo mirrors (called something like 'openpic-bugfix') which should AFAIK boot any openfirmware mac.

Hope it helps...

Thanks for the info linux is indeed installed on the first partition, so resetting the firmware should di the trick for me.

Yes, I know, but it's not booting on my computer

So were you able to boot a live cd on a panther machine ? I wanted to install Gentoo on my powerbook. I burned the cd, re-booted with command+option+o+f and got the globe, then I got a folder with the finder logo and a question mark.... I guess the question mark was the cd but it would only boot OSX... am I doing something wrong ?

I burned the cd on mt gentoo x86 box, using cdrecord at the command line. no special flags but I've burned lots of bootable x86 linux cds that way no problem. Thanks for any help here :?

Well, my problem is fixed (see the other thread: link in first message of this thread)

clar77: I think the flashing icon you get means it can't find anything to boot from
To boot from cd you have a few options: simplest one: turn of mac, hold down the c button while you push the power button and keep the c button down untill you see it's booting.
slightly fancier (for newworld macs only): same but with the alt button: you will get a few buttons with all the bootable media in your mac. select the CD and then the right arrow
And then you can try the guru-way: boot in openfirmware: alt-apple-o-f and find find out the right command to type in (see the thread I linked to earlier). This never worked for me though (but I havn't tried again since I can boot from CD).
Hope this helps you,

Jan.
