Changing BIOS settings Via GPO

Hello All,

We've recently begun deploying Windows 7 using WDS. We use a wide range of Dells, 745's to 780's. During the upgrade process, I would like to be able to set the machines to boot to pxe without having to go to each of them. (Around 300-500 machines.) and some of them are currently running XP. However, after they get switched to Windows 7, the boot order will need to be changed back to where pxe isn't first in the order.

. I was wondering if anyone has had success with Dell CCTK changes over GPO? I've tried having it set as a startup script which will simply run an executable, and it doesn't work on Windows 7. (assuming UAC related?) But I disabled UAC and still nothing. I've tried having it run via command line. (navigate to cctk, cctk -i ) but the changes don't seem to be occuring. Has anyone had luck making these changes remotely via gpo? Or even remotely period? Without having to remote into each machine... Thanks ahead of time! Any tips are appreciated.
