- Download 'DOS Files' here. Save this file inside 'Toolbox' folder.
- Download 'Flash It Tool' here. Save this file inside 'Toolbox' folder.

- Step 1 done.

- Step 4 done.
Step 5 - Finding the flasheable EFI file
- In 'platform.ini' file, search for the section called '[FDFile]'.
- Look for the 'FileName' attribute. This attribute sets the flasheable EFI file name.
- Look inside your 'EFIUPDATEPACKAGE' folder for that file, and rename it to 'FLASHME.ROM'.
- Copy 'FLASHME.ROM' file to the root directory of your USB stick.
- Step 5 done.
