UEFI
From Lazarus wiki
Motivations behind this target
Unified Extensible Firmware Interface (UEFI) now replace BIOS in most current PCs.
Currently, there is two main options to develop UEFI applications :
- Tianocore : http://www.tianocore.org/ - gnu-efi : http://sourceforge.net/projects/gnu-efi/
Both solutions require a tedious setup process.
Thank to his internal linker, Freepascal can become the easiest option to develop UEFI applications, as no external tools would be required to start hacking.
