Le code est distribu\u00e9 sous la licence GPLv3.      <\/p>\n<p>Le projet impl\u00e9mente \u00ab NT Executive \u00bb, l'un des niveaux du noyau Windows NT (NTOSKRNL.EXE), responsable de la fourniture de l'API des appels syst\u00e8me NT Native et d'une interface pour le fonctionnement des pilotes. Dans Neptune OS, le composant NT Executive et tous les pilotes s'ex\u00e9cutent non pas au niveau du noyau, mais sous forme de processus utilisateur dans un environnement bas\u00e9 sur le micro-noyau seL4. L'interaction du composant NT Executive avec les pilotes se fait via l'IPC standard de seL4. Les appels syst\u00e8me fournis permettent d'assurer le fonctionnement de la biblioth\u00e8que NTDLL.DLL avec l'impl\u00e9mentation de l'interface de programmation Win32, utilis\u00e9e dans les applications.    <\/p>\n<p>La premi\u00e8re version de Neptune OS comprend un pilote de clavier (kbdclass.sys), un pilote de port PS\/2 (i8042prt.sys), un pilote de son (beep.sys) et un interpr\u00e9teur de ligne de commande (ntcmd.exe), transf\u00e9r\u00e9s de ReactOS et permettant de d\u00e9montrer les principes fondamentaux de l'organisation du travail. La taille de l'image de d\u00e9marrage est de 1,4 Mo.         <\/p>\n<p>L'objectif final est d'amener la couche \u00e0 un \u00e9tat suffisant pour le portage de l'environnement utilisateur et des pilotes de ReactOS. Les d\u00e9veloppeurs envisagent \u00e9galement la possibilit\u00e9 d'atteindre une compatibilit\u00e9 binaire avec les fichiers ex\u00e9cutables Windows et une compatibilit\u00e9 acceptable au niveau des sources avec les pilotes du noyau Windows.     <\/p>\n<p>Comme principal obstacle \u00e0 la prise en charge des pilotes Windows, on cite l'utilisation dans la plupart des pilotes du noyau Windows d'un protocole de communication non standard lors de l'acc\u00e8s \u00e0 d'autres pilotes, utilisant plut\u00f4t le passage direct de pointeurs, ce qui ne peut pas \u00eatre r\u00e9alis\u00e9 dans
