After update, hangs at grey apple logo, Still waiting for root device

[charliej]

Hey,

 

I installed fine and thanks for everyone on this forum for all the documentation to get Leopard installed.

 

After the update, I try and boot and it just hangs on the Apple logo screen, after fixing an error with the AppleIntelPowerManagement.

 

Now if I try and boot up with all different attributed (-x -f) I get "Still waiting for boot device" and in yellow, "Failed to load extension com.apple.driver.AppleACPIPCI".

 

Thanks for all your support
