First of all, if you are working with Windows 7, then you need to have Ghost Solution Suite 2.5.1 at build 2266 or higher.
The Deploy Anywhere drivers need to be appropriate to the operating system you are deploying, so for Windows 7, you would add the necessary Windows 7 drivers.
However, drivers for WinPE need to be Vista 32 bit drivers, as the version of WinPE provided with Ghost Solution Suite, is V2, which is based on the Vista kernel.
There are many past postings with links to driver downloads for various Intel chipsets, so I would suggest using the search engine to look for past postings on the 82578 chipset. Not all download locations offer drivers that work with WinPE, with the 82579 chipset proving to be particularly challenging to get working.
