Problems when booting without USB Key / DVD

[Dean Vesuvio]

I've successfully installed Snow Leopard and can boot just fine, so long as I boot from the USB key that I used to install from. I select my main hard disk at the startup prompt and everything proceeds fine from there.

 

I notice that when I do this, the apple logo during the boot process is flatter and older looking.

 

If instead I remove the USB key, it will start to boot from the hard drive, but then Kernel Panic. I notice that during this boot process, the Apple logo is more 3D looking.

 

The panic has something to do with HPET and appleintelcpupowermanagement. I can get the exact text of the Panic, but I think others have talked about this before.

 

What's truly odd to me is that this panic only happens when I boot without the USB key. I can't understand why this makes a difference, since it seems to me that in either case I'm booting the same Kernel and the same set of Extensions.

 

Does anyone have any ideas? I'd rather not just eliminate appleintelcpupowermanagement, since it seems like it works ok from the USB key. Also, I'd rather not leave the USB key plugged in all the time, though that would be an acceptable solution I guess. Mostly I'm just curious what's going on.

Im not pro at this dude, but the diference on "logos" are the Bootloaders (Chameleon). On the power management i hade this error and remove the kext (backup) from "system/library/extension/" but I have "/Extra/AppleCPUPowerManagement.kext" (that i have for my XPS 1530). Try that (not sure if the way to go but the kernel panics refer to that are not apearing any more for me).

Its something with the uuid boot change when you dont have the usb key.. i got the same. i will post as soon i found how to change it..

[Dean Vesuvio]

I solved it actually.

 

The problem was very simple. My USB key had an Extras folder that I had neglected to copy to my hard disk.

 

I copied that folder, rebooted and voila!

 

Thanks for your help.
