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\/10.<\/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

\n – CPU: implemented new instructions and x86 architecture extensions.
\n – Bugfixes for CPU emulation correctness.
\n – Added Android host platform support.
\n – Added USB EHCI device emulation support.
\n – Added USB floppy (UFI\/CBI) support.
\n – Added ethernet module ‘socket’, designed to interconnect Bochs instances.
\n – Show textconfig at runtime in the Bochs VGA window (gui console).
\n
\nDetailed change log :<\/p>\n
\n – Added new log action \u00ab\u00a0warn\u00a0\u00bb, designed to show a message box on error events.
\n – Show message box before exit if log action is set to \u00ab\u00a0fatal\u00a0\u00bb.
\n – Added macro BX_FATAL for all cases when continuing is not recommended, since
\n it can cause an application crash or incorrect simulation behaviour.
\n
\n– Configure and compile
\n – Added Android host platform support.
\n – Configure script now prints warnings for features not maintained yet.
\n
\n– GUI and display libraries
\n – Show the runtime configuration in the Bochs VGA window (gui console) instead
\n of console \/ xterm (rfb, sdl, sdl2, vncsrv and X11 guis).
\n – SDL2: Added get\/set clipboard text support.
\n
\n– CPU \/ CPUDB
\n – Bugfixes for CPU emulation correctness (critical bugfix for x86-64 and AVX opcodes emulation,
\n fixed assertion failures in proc_ctrl.cc)
\n ! VMX: Implemented Page Modification Logging (PML)
\n ! VMX: Implemented TSC Scaling Extension
\n ! Paging: Implemented Protection Keys
\n ! Implemented UMIP: User Mode Instruction Prevention (don’t allow execution of SLDT\/SIDT\/SGDT\/STR\/SMSW with CPL>0)
\n ! Implemented RDPID instruction
\n ! Implemented VPOPCNTD\/VPOPCNTQ AVX512 instructions
\n ! Implemented XSAVES\/XRSTORS instructions and IA32_XSS MSR
\n ! Implemented Translation Cache Extensions (TCE) for AMD CPUID and EFER.TCE control
\n ! Implemented CLZERO instruction (AMD), enabled in Ryzen CPU model
\n ! Implemented MONITORX\/MWAITX instructions (AMD), enabled in Ryzen CPU model
\n ! CPUDB: Added AMD Ryzen configuration to CPUDB
\n
\n– I\/O Devices
\n – Busmouse
\n – Added standard bus mouse support in addition to the existing InPort
\n emulation code. (patch by Ben Lunt).
\n – Hard drive
\n – Implemented lock mechanism for hard disk images. An image that is opened
\n in r\/w mode cannot be used multiple times (e.g. by another Bochs session).
\n – Several fixes in some disk image modes.
\n – Serial \/ Parallel ports
\n – Added support for changing output file at runtime.
\n – Networking
\n – Added ethernet module ‘socket’, designed to interconnect Bochs instances
\n with external program ‘bxhub’ (simulating a multi-port ethernet hub).
\n – Now creating separate plugins for each network driver implementation
\n (slirp, win32, etc.).
\n – Sound
\n – Added PCM output data resampling in a separate thread. The resampler
\n requires either libsamplerate or the SoX resampler library installed.
\n – SDL: Added audio capture support (requires library version >= 2.0.5).
\n – Now creating separate plugins for each sound driver (alsa, win, etc.).
\n – USB
\n – Added USB EHCI device emulation support (EHCI core ported from Qemu).
\n – Added USB floppy (UFI\/CBI) support (patch by Ben Lunt).
\n – Added asynchronus USB packet completion support (needed by disk\/cdrom
\n seek and read\/write latency emulation).
\n – Implemented USB remote wakeup mechanism.
\n – Fixed NAK response handling in all USB HCs.
\n – USB printer: added support for changing output file at runtime.
\n – Added common USB device option \u00ab\u00a0debug\u00a0\u00bb to turn on BX_DEBUG reporting at
\n connection time.
\n
\n– ROM BIOS
\n – Implemented Bochs BIOS option \u00ab\u00a0fastboot\u00a0\u00bb for skipping the boot menu delay.
