UEFI in Flat Assembly - FASM

This code shows how to assemble the UEFI BOOTX64.EFI file in Assembly Code using FASM.

NOTE : I am re-uploading this do to a few requests. Keep in mind, this is no longer being updated.

Tool Needed

FASM
https://flatassembler.net/

VirtualBox
https://www.virtualbox.org/

Notepad++
https://notepad-plus-plus.org/

UEFI Specs PDF
https://uefi.org/specifications

OSFMount

NOTE :
This is an unfinished project. I put this here for others to continue my work if they wish.

NOTE 2 : I originally used the UEFI 2.8b PDF specs for this project, but should be 100% compatible with the UEFI 2.9 PDF specs.

NOTE 3 : I included the imagecreator so you can create the 256 meg raw drive.hdd file to be mounted with OSFMount, GPT / EFI partitioned with the use of windows partition program ( comes with windows ) and then you can drag your EFI file to EFI/Boot/ folder. ( You have to create those folders. ) VirtualBox is compatible with HDD files. Just mount it like a hard drive. QEMU also works with HDD files.

PROGRESS:

- [x] TEXT  
- [x] COLOR  
- [x] KEYBOARD  
- [x] ERROR CHECKING  
- [x] GOP  
- [x] COMPUTER REBOOT - COLD, WARM, SHUTDOWN  
- [x] FILE SYSTEM LOADING  
- [x] OPEN FILE HANDLE  
- [x] CLOSE FILE HANDLE  
- [x] ALLOCATEPOOL AND READ FILE INTO BUFFER  

Planned, but never finished:

- [ ] GRAPHIC TEXT
