Bochs est un \u00e9mulateur PC tournant sous Windows, son d\u00e9veloppement s’effectue en Open Source. Ecrit en C + +, il fonctionne sur la plupart des plates-formes populaires. Il inclut l’\u00e9mulation des CPU x86 d’Intel, les p\u00e9riph\u00e9riques E \/ S courants et un BIOS personnalis\u00e9. Actuellement, Bochs peut \u00eatre compil\u00e9 pour \u00e9muler un processeur 386, 486, Pentium\/PentiumII\/PentiumIII\/Pentium4 ou x86-64, y compris MMX option, SSEX et 3DNow! instructions.Bochs est capable d’ex\u00e9cuter la plupart des syst\u00e8mes d’exploitation \u00e0 l’int\u00e9rieur de l’\u00e9mulation, y compris Linux, DOS, Windows \u00ae 95\/98 et Windows \u00ae NT\/2000\/XP ou Windows Vista\/7\/8.<\/p>\n
<\/p>\n
L’utilisation \u00abtypique\u00bb de Bochs est de fournir \u00e9mulation PC x86 compl\u00e8te, y compris le processeur x86, des p\u00e9riph\u00e9riques et la m\u00e9moire. Cela vous permet d’ex\u00e9cuter OS et des logiciels au sein de l’\u00e9mulateur sur votre poste de travail, un peu comme si vous aviez une machine \u00e0 l’int\u00e9rieur d’une machine. Par exemple, disons que votre poste est un poste de travail Unix\/X11, mais que vous souhaitez ex\u00e9cuter des applications Win’95. Bochs va vous permettre d’ex\u00e9cuter Win 95 et le logiciel associ\u00e9 sur votre poste de travail Unix\/X11, affichant une fen\u00eatre sur votre poste de travail, simulant un moniteur sur un PC.<\/p>\n
