Hey all,


working on putting Leopard 10.5.1 Kalyway on my laptop.


I'm getting a kernel panic that has to do with AppleIntel8254XEthernet ... if I uninstall it or delete it, I should be able to boot into the actual OS... So...


Anyone know where this file is located so I can delete it?


I found this: http://forum.insanelymac.com/lofiversion/i...php/t55886.html


where someone had the exact same problem. I tried to use the extension that he used on Tiger, but it didn't work - IOPCI is where it failed.


Anyone have any ideas?


Many thanks!

You've probably already figured this out, but . . .


Press F8 at boot to get Darwin boot options


add -s as a boot option to boot into single user mode


run the commands to mount your drive ('/sbin/fsck -fy' and then '/sbin/mount -uw /' both of these are displayed when you get into single user mode)


then cp -R /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntel8254XEthernet.kext /<backuplocation>

then rm -R /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntel8254XEthernet.kext
