I wonder if there is a UI framework for making minimalistic and beautiful apps that work without OS, the things that we see in UEFI settings like this:
Build GRUB
git clone https://git.savannah.gnu.org/git/grub.git
cd grub
./bootstrap
# EFI
./configure \
--with-platform=efi \
--target=x86_64 \
--disable-werror \
--prefix=$(pwd)/../grub-install
# BIOS
./configure \
--with-platform=pc \
--target=i386 \
--disable-werror \
--prefix=$(pwd)/../grub-install
make
make install
cd $(pwd)/../grub-install/bin
find ../lib/grub/x86_64-efi -name '*.mod' \
| sed -e 's/..\/lib\/grub\/x86_64-efi\///g' \
| sed -e 's/\.mod//g' \
| sort > modules.list
./grub-mkimage \
--format=x86_64-efi \
--output=bootx64.efi \
--prefix='(tftp,192.168.3.146)/grub' \
--verbose $(<modules.list|tr '\n' ' ') > grub-mkimage.log 2>&1
# modules = efinet tftp chainBuilding BIOS version you can get this error:
/usr/bin/ld: relocatable linking with relocations from format elf64-x86-64 (lib/zstd/zstd_module-debug.o) to format elf32-i386 (zstd.module) is not supportedTODO - how to fix it?

Font customization
./grub-mkfont -s 24 -o Sarabun_24.pf2 Sarabun-Regular.ttf
./grub-mkfont -s 16 -o Sarabun_16.pf2 Sarabun-Regular.ttf
./grub-mkfont -s 32 -o Sarabun_32.pf2 Sarabun-Regular.ttfedk2
Build edk2 example
sudo pacman -Syu nasm
git clone https://github.com/tianocore/edk2.git
cd edk2
git submodule update --init
source edksetup.sh BaseTools
# turn off warnings as errors: modify settings under Conf/tools_def.txt
# to remove the warnings-as-errors flag
# ref: https://edk2-devel.narkive.com/i74qD279/edk2-how-to-turnoff-error-c2220-warning-treated-as-error-edk-ii
make -C BaseTools/Source/C- edit Conf/target.txt
TARGET_ARCH = X64
TOOL_CHAIN_TAG = GCC- create MyHelloWrold/MyHelloWrold.c
- create MyHelloWrold/MyHelloWrold.inf
- edit ShellPkg/ShellPkg.dsc
- add into [Components]:
MyHelloWorld/MyHelloWorld.inf - if you see BaseTools C Tool binary was not found (GenFw) you may need to run
make -C /scgames/installer/edk2/BaseTools/Source/COther links
