Boot HTTPS failing with "Unable to retrieve NBP file size from http server"


  • Hi,
    I am trying to do a UEFI Shell HTTPS boot from BIOS network settings.
    I have installed Apache 2 on my Win-10 Desktop (this will act as my HTTP Server). It is able to launch Local Host Successfully.
    I have generated .cert, .key, .csr and .pem files. But I don’t know where or how to use these.
    Next, I have a server (which will act as my client). I have enabled HTTPS Device 1 and in its settings.
    Have mentioned Shell.efi in “C:\Program Files\Apache24\htdocs” path.

    While booting from HTTP , this fails with “Unable to retrieve NBP file size from HTTP server”.
    I am doing this for the first time, what I understood from my search is, NBP has to be some file “wdsmgfw.efi” where can I find this and where shall I put it.

    @Navdeeppal While we use PXE boot a lot in FOG I don’t see what your question has to do with the FOG Project?!
