WinPE, Console, Windows 7 Drivers

Hi

We use ghost console to deploy images to muliple machines using the ghost client.

We have just purchased some Dell E5430's, but looking on the website there does not appear to be any Vista drivers available to create the WinPE PreOS

1) Is there a recommended route to follow when this happens?

2) Is it worth me even trying the Windows 7 drivers in the PreOS?

3) Failing any solution to this, I guess I should revert back to PC-DOS and DOS NIC drivers?

Thanks for any help :)
