make -C limine
mkdir -p iso_root

cp -v bin/blazeos limine.cfg limine/limine-bios.sys limine/limine-bios-cd.bin limine/limine-uefi-cd.bin iso_root/

xorriso -as mkisofs -b limine-bios-cd.bin \
        -no-emul-boot -boot-load-size 4 -boot-info-table \
        --efi-boot limine-uefi-cd.bin \
        -efi-boot-part --efi-boot-image --protective-msdos-label \
