Anybody trying to deploy a UEFI/SecureBoot based computer with WDS? RRS feed

  • Question

  • OK, here is the issue: My UEFI/SecureBoot enabled computers (Lenovo ThinkPad T430s, T440s, T440p, X230, X240, all 64bit) that are booting from WDS only get a 640x480 display resolution.

    I'm using the unmodified WinPE 5 from ADK 8.1 but I have the same issue with WinPE 4 from ADK 8.0. Booting this WinPE 5 wim from USB results in a native (based on EDID, 1920x1080) resolution which is expected. Booting the same wim from WDS (tried 2008 R2 and 2012) I only get 640x480. Even after adding display drivers and providing an answer file the resolution stays at 640x480 when bootign from WDS.

    As soon as I go back to BIOS or turn on CSM support with UEFI enabled, the display resolution is 1024x768 (no change on the WinPE wim, just different BIOS settings).

    So, the question is, does anybody here boot a UEFI/SecureBoot enabled computer from WDS with the original WinPE 4/5 and gets more than 640x480?

    Thanks,

    Dirk

  • Hi, 

    Based on my research, Once UEFI has determined which display is enabled to display the pre-operating system screen, it must select the mode to apply based on the logic in this article: 

    UEFI GOP mode Test

    http://msdn.microsoft.com/en-us/library/windows/hardware/hh997769.aspx 

    In your situation, it seem that in UEFI, display resolution is by default to set as 640*480.

    As I known, MDT has integrated some scripts can bypass this.

  • Hi,

    You can try to use unattend.xml to configure the resolution, refer to following article:

    Setting screen resolution in WinPE 4.0

    http://www.deploymentresearch.com/Research/tabid/62/EntryId/51/Setting-screen-resolution-in-WinPE-4-0.aspx

    The fact that WDS can only provide bare-metal installations. Thick images are your only option and if you want to make a change to an OS image you have to export the image from the WDS snap-in, use the Windows AIK tools to make your changes and add it back to the WDS snap-in. If you need to perform a refresh or replace scenario you would need to fully script them yourselves. I say why bother – MDT 2010 U1 does all this for you and more!

    We can also try to use MDT 2012, which can integrate script to configures MDT to allow the graphics driver auto detect method to set the screen resolution. The similar

  • The process described in http://www.deploymentresearch.com/Research/tabid/62/EntryId/51/Setting-screen-resolution-in-WinPE-4-0.aspx does not work for UEFI/SecureBoot enabled Lenovo laptops.

    This question is not about MDT, it's about WDS and WinPE. I'm looking for anybody who has successfully booted a UEFI/SecureBoot enabled computer with more than 640x480 from WDS using WinPE 4 or 5.
