По уточнению @lzcnt (нужен EFI-загрузчик, не a.out-парсер, и amd64-ядро):
- kernel.c + kern64.s -> 6c/6a/6l -> amd64 Plan9 a.out (S_MAGIC 0x8A97, entry 0x100000),
kmain пишет строку в VGA 0xB8000.
- efi_load.c -> PE32+ bootx64.efi (через pe64.s из 9legacy + dd skip=40): под UEFI
печатает через ConOut, разбирает встроенный a.out (big-endian 40-байтный заголовок),
копирует сегменты по entry, прыгает в ядро (long mode).
- Проверено: валидный PE32+ x64 EFI_APPLICATION, ядро встроено и парсится, ESP собран.
