My wife's G4 iBook (1.33 mhz/ 2GB RAM) is too slow on Leopard 10.5 8. Today, I created a clone of the HD via SuperDuper, then ran the Tiger installer disk (10.4.2). There, I customized the install, plus selected "Erase and Install". No problems during installation. However, after the new install>welcome movie is underway, a kernel panic occurs either just before the wireless input panel appears, or during the entry of my wireless password. This happened 3 times today.

Hence, I booted from the 10.5.8 clone, then reinstalled 10.5.8 back to the iBook's HD. Once re-installed, no kernel panic occurred. Been using the machine for about an hour - same slowness, but no KP. This has me quite mystified. What would trigger a KP on Tiger, but not Leopard?

    Mysterious, indeed! From your description I am wondering if there is not some kind of incompatibility or other wrinkle in the wireless connection phase.
    a kernel panic occurs either just before the wireless input panel appears, or during the entry of my wireless password.

    The fact that it happens in Tiger but not with Leopard is puzzling. It would seem that if it were hardware it would be the same with either OS. That seems to suggest that something in the Tiger wireless setup might be amiss.

    Sorry, but that's the best I can do at the moment. Please post back if you have found anything else.

    if I follow the poster's suggestions by replacing the Apple extension with a bogus version, seems I would not be able to use Airport. Do you concur?

    I do concur. Besides, why go to all that trouble to make the Airport Extreme card useless when you can either turn it off or else completely remove the card?

    Have you tried turning off Airport and using an Ethernet connection? This might be worth it, if it works, to get Tiger installed. The other thing you might want to do is remove the AE card, and then reinstall it making sure it is securely seated. We know that AE is a prime suspect with KPs. However, in this case you have the same hardware configuration with both Tiger and Leopard, and KPs in Tiger but not Leopard. If the Ethernet part works for installation you can then turn Airport on again after installation and see what gives. At least it will give you a chance to complete the installation and then mess around a bit.

    Hi,

    Just a thought if you haven't already tried...

    Maybe somewhere along the line Tiger/Leopard pref files became corrupted.

    Go to /Library/Preferences. Move all the files on the System Configuration folder to the Trash including the Preferences.plist file. Reboot the iBook.

    Hi,

    Thought it was worth a shot.

    My iBook is running v10.4.11 with Safari 4.1.3. I keep my fingers crossed.

    Joseph:

    Congratulations! Glad that worked, and you even have Airport working. Wonderful.
    now that I'm back in 10.4.11 I'm going to have to find earlier versions of Tiger compatible software. I knew I should have kept those old files.

    That's always a tough call between keeping everything, managing them, and space considerations. I seem to have everything around somewhere, if I could only find it.

    In any case, how your wife rewards your diligence handsomely.

    Best Wishes.
