UEFI-helloworld

A hello world example for UEFI written in x86 NASM assembly

How to use:

Running make will:

• Assemble the files from src into win64 object files, and put them in obj
• Link the win64 object files from obj into a PE32+ executable, and put it in efi
• Create a FAT32 .img file in the current working directory, and move the PE32+ executable from efi into that .img file at the location EFI/BOOT/BOOTX64.EFI which is the default filename for a 64-bit UEFI application.

You can then run make qemu to boot that UEFI application with the UEFI provided by OVMF from the TianoCore project that's stored in inc.
