      you can extract the recovery module in the boot block partition (02) of the UEFI module.
      open it up with your hex editor, you will find the names for the rom or hdr file there.

      first of all, disconnect the cd-rom and harddrive phsyically from your notebook.
      warning: the connector for the harddrive is a little bit fragile ->
      pull on the right and left foots to open it up.
      now pull the ribbon cable out.
      if you are unsure, you can use this owner guide from the dell website.

      format a usb stick with RUFUS.

      Select first the USB stick you want to format.
      Warning: All data on this USB stick will be lost.
      Use MBR partition scheme for BIOS or UEFI, FAT32 (Default), Cluster Size 8192 bytes (Default).
      The volume label doesn't matter.
      Set a tick at quick format.
      Untick "Create a bootable disk using..."
      Untick "Create a extended label and icon files"

      Download the UEFI version that was at last on your notebook.
      if it was version A07, then download A07.
      if it was version A10, then download A10.

      Extract from 3350A10.exe / 3350A07.exe the UEFI file.
      Open up a cmd and enter the following command: 3350A10.exe /writehdrfile
      Rename the rom file to 3350.hdr and move it on the usb stick.

      Disconnect the battery from your notebook.
      Plug In the pendrive.
      Press the end key and hold it down.
      Connect the charger (still hold END).
      The notebook starts automatically and shows the recovery screen.
      Press enter and wait until finish the flashing.
      Press any key to restart.
      The first restart attempt wouldn't be successful.
      The second one would work.
      Give it a little bit time between the start attempts.

      ah i see, it's the recovery module in Volume 02.
      i opened it in the hex editor:
      the name of the recovery rom seems to be 3350.hdr or DN13A10.rom.
      however, there is nothing shown on the screen if i follow the recovery procedure.
      In the same file the El Torito specification is mentioned...
      maybe that's the right way.

      i believe, the filesystem module for fat32 isn't integrated into this UEFI.
      following ideas:
      integrate the filesystem module into the UEFI and try again to load the UEFI Shell.
      or
      replace the ePSA (Enhanced Pre-Boot System Assessment) Test Module against a UEFI Shell.

      Anybody experience with that?

      Kind Regards,
      MaCXyLo

      Hey,
      thanks for your hints.
      i begin to edit the options.

      I edited the Array to unlock the other tabs:
      010100010101000000000000 <- original
      010101010101010101010101 <- with intel

      Then i switched the following bits:
      0A 82 46 02 <- true
      to
      0A 82 47 02 <- false

      1E 82 46 02 <- true
      to
      0A 82 47 02 <- false

      No success...
      Can someone take a look @ my setup-ifr.txt file? Thanks!
