    WES7 Signed drivers for EG20T / EMGD

    Green Belt

      I am trying to build an OS installation image for Windows Embedded Standard 7 SP1 (WES7) using the Image Configuration Editor (ICE).  I've managed to capture the Intel drivers for the graphics and EG20T controller, but Windows won't install those because (I'm guessing) that they are not signed.


      When I look at the setup logs, I can see that Windows finds the drivers but chooses the standard VGA that is signed.  When I update the drivers after installation, the driver is listed but shows as unsigned.


      If I install the drivers after installation using the setup program, I get numerous dialogs about each driver not being signed.


      Are there signed drivers available to allow me to create a totally hands-off image disk?  Or is there a mechanism to turn off the check for signed drivers for WES7 without it being a "test" image?

          Exactly which EMGD are you using?  It sounds like you might be using the XP version on Win7 (which is allowed), however, WHQL and signing is not a feature of the XP driver set as we opted to give the driver higher flexibility and easier "on-the-fly" changability for configurability that a consumer (like notebook or desktop) driver cannot give.  The issue is that to be signed, the INF has to be part of the signing and since we give YOU the ability to change the INF, then you would need to get it signed by Microsoft.  The INF is the key to flexibilty but Microsoft does not like that sort of thing to change so we have to live with the difficulties with being unsigned.


          I know in XP there used to be a way to turn off the "unsigned" gripping, and at one time I thought I had found similar capability in Win7 but that may not apply to WES7.  The best thing to do would be to check on MSDN to see if there is a Microsoft proceedure to lighten up the signed driver policy.


          Sorry I cannot help more.
