UEFI Bootable image loader

This is a simple UEFI-bootable program which prints an image of specific size on screen using the GOP protocol which is provided by the UEFI firmware. This project was done as a hobby.

Note

1. The image must be .bmp image.
2. The image must be mirror-inverted to print it upright and correctly. A sample of the mirror-inverted image is the image.bmp (provided in the source). It is also the default image file that is used by the program.
3. The resolution of the image must be 2560x1440 as the default graphics mode has the same resolution. This could be changed if a different graphics mode is used.

Tools:

1. Unix environment.
2. make.
3. Qemu (virtual machine).
4. UEFI firmware for qemu.[Provided in the OVMF folder]
5. gdisk.
6. edk2.

How to build:

Getting edk2

1. Download the EDK II source and build tools.
   $ git clone https://github.com/tianocore/edk2.git, or
   
2. Download the latest .zip UDK2017 Download release (or Latest UDK release).

Install dependencies:

For Debian based Linux

$ sudo apt-get install build-essential uuid-dev iasl git gcc-5 nasm python3-distutils

Building the edk2 tree and efi application.

1. Follow instructions at https://github.com/tianocore/tianocore.github.io/wiki/Getting-Started-with-EDK-II and https://github.com/tianocore/tianocore.github.io/wiki/Common-instructions to build the edk2 tree.
2. Open the file edk2/DuetPkg/DuetPkgX64.dsc and add our application to the the [Components] section and before the [BuildOptions] section. Just add the absolute path of main.inf file betweem [Components] section and the [BuildOptions] section.
3. To build the UEFI application:
   $ build -a X64 -p DuetPkg/DuetPkgX64.dsc It will take a while to build.
4. To create the disk image
   $ make set_disk

• on the first entry, enter :n, to create a new partition.
• on the second entry, enter :1, for one partition.
• on the third entry, enter :set default sector size.
• on the fourth entry, enter :set the default last setor.
• on the fifth entry, enter :ef00, this implies an efi partition.
• on the sixth entry, enter :w, this marks the changes to be written on the disk.
• on the seventh entry, enter :Y, to perform the final write operation. The disk will be created.

5. To prepare the disk
   $ make prep_disk This will create /efi/boot and /img directories and also copy the .efi application and the image file to the disk.
6. To run the application on the qemu VM.
   $ make run-qemu.
