O c\u00f3digo \u00e9 distribu\u00eddo sob a licen\u00e7a GPLv3.      <\/p>\n<p>O projeto implementa o 'NT Executive', um dos n\u00edveis do n\u00facleo Windows NT (NTOSKRNL.EXE), respons\u00e1vel por fornecer a API de chamadas de sistema NT Native e uma interface para a opera\u00e7\u00e3o de drivers. No Neptune OS, o componente NT Executive e todos os drivers s\u00e3o executados n\u00e3o no n\u00edvel do n\u00facleo, mas na forma de processos de usu\u00e1rios em um ambiente baseado no microkernel seL4. A intera\u00e7\u00e3o do componente NT Executive com os drivers acontece atrav\u00e9s do IPC padr\u00e3o seL4. As chamadas de sistema fornecidas permitem o funcionamento da biblioteca NTDLL.DLL com a implementa\u00e7\u00e3o da interface de programa\u00e7\u00e3o Win32, utilizada em aplicativos.    <\/p>\n<p>A primeira vers\u00e3o do Neptune OS inclui o driver de teclado (kbdclass.sys), o driver de porta PS\/2 (i8042prt.sys), o driver de sinal sonoro (beep.sys) e o interpretador de linha de comando (ntcmd.exe), transferidos do ReactOS e que permitem demonstrar os princ\u00edpios b\u00e1sicos da organiza\u00e7\u00e3o do trabalho. O tamanho da imagem de inicializa\u00e7\u00e3o \u00e9 de 1,4 MB.         <\/p>\n<p>O objetivo final \u00e9 levar a camada a um estado suficiente para portar o ambiente de usu\u00e1rio e drivers do ReactOS. Os desenvolvedores tamb\u00e9m consideram a possibilidade de alcan\u00e7ar compatibilidade bin\u00e1ria com arquivos execut\u00e1veis do Windows e compatibilidade aceit\u00e1vel em n\u00edvel de c\u00f3digo-fonte com os drivers do n\u00facleo do Windows.     <\/p>\n<p>Um dos principais obst\u00e1culos para garantir o suporte a drivers do Windows \u00e9 o uso de um protocolo de comunica\u00e7\u00e3o n\u00e3o padr\u00e3o na maioria dos drivers do n\u00facleo do Windows ao interagir com outros drivers, na forma de passagem direta de ponteiros, o que n\u00e3o pode ser
