1. UEFI article:

   TODO - I'd like to show a breakdown of a PE file containing a UEFI application here.

   Not sure what exactly the breakdown is meant to show. Yet both

   Code: Select all

   objdump --all-headers filename

   , and

   Code: Select all

   exiftool filename

   , will show a breakdown. In particular, they will show the type of the UEFI image. That is, the subsystem. exiftool is from https://sno.phy.queensu.ca/~phil/exiftool/
2. UEFI Bare Bones article:
   I am only a beginner. Yet my little experience is that one detail is wrong. In hello.c, the message will stay on screen until the screen will be filled with more lines. Which it will not in this case. This is in contrast to the comment in the code. Therefore, I suggest the following:

   Code: Select all

   --- hello.c	2019-03-21 23:03:42.301082430 +0000
   +++ -	2019-03-23 00:54:09.103781868 +0000

        if (EFI_ERROR(Status))
            return Status;
     
   -    /* Now wait for a keystroke before continuing, otherwise your
   -       message will flash off the screen before you see it.
   +    /* For demonstration purposes, wait for a keystroke before continuing.
     
           First, we need to empty the console input buffer to flush
           out any keystrokes entered before this point */
