Cet émulateur de PC est Open Source mais pas aussi simple d'emploi qu'un Parallels Desktop.

Seul le code source est disponible et la version Mac ne semble pas à jour.

Changelog

3.0

Brief summary :

Include Bochs debugger support in all release binaries.
Bochs internal debugger and Bochs GUI debugger are compiled in by default and
there are no special Bochs binaries with internal debugger support anymore.
Integrated softfloat3e library replacing older softfloat2a fpu-emulation code
Bugfixes for CPU emulation correctness (critical bugfixes for VMX, WAITPKG, LASS,
XSAVEC/XSAVES, CPUID and SHA1 ISA implementation)
Added emulation of missing AMD 3DNow! instructions
Implemented AVX512_FP16 Intel instruction set based on softfloat3e library
(enabled in Xeon Sapphire Rapids CPU definition)
Implemented MONITORLESS MWAIT instructions support
Implemented initial support for AVX10_1 + AVX10_2 ISA extensions and AVX10
CPUID leaf 0x24 (AVX10_1 first to be enabled in Xeon Granite Rapids)
Implemented AMX-TF32 and AMX-AVX512 ISA extensions
Implemented RAO-INT ISA and MSR_IMM ISA extensions
CPUID: Added new CPU definitions: for i386, i486DX4, AMD Athlon XP and Intel Core i5 Arrow Lake CPUs
CPUID: Support for enabling/disabling of one or more CPU features from CPUID
configuration (see "add_features" and "exclude_features" in bochsrc sample and documentation)
! CPUID: Old bx_generic CPUID model is deprecated with all associated .bochsrc
CPUID configuration options, use pre-defined CPU models instead
Several fixes and improvements for the Cirrus and Voodoo emulation
USB: Added the USB Debugger support for xHCI and UHCI (Windows / GTK3)
Added USB boot option (requires i440fx.bin BIOS)
LGPL'd VGABIOS updated to version 0.9c (Cirrus / VBE fixes and extensions)
Added i440fx.bin BIOS written by Ben Lunt (https://github.com/fysnet/i440fx)
Documentation updates and fixes after transition to GIT

2.8

Brief summary of changes :

Bugfixes for CPU emulation correctness (MONITOR/MWAIT, VMX/SVM, x87, AVX-VNNI, AVX-512, CET)
- Critical CPU emulation bugfixes for SHA and GFNI instructions, ADOX and XRSTOR/XRSTORS instructions (prevented boot of Win10)
  ! SVM: Implemented SVM VM_CR_MSR and INIT redirect (required for booting SMP with SVM)
  ! Implemented VMX MBE (Mode Based Execution Control) emulation required for Windows 11 guest
  ! Implemented VMX 'Shadow Stack Prematurely Busy' control
  ! Implemented MSR IA32_SPEC_CTRL Virtualization VMX extension
  ! Implemented Posted-Interrupt Processing VMX extension emulation
  ! Implemented Linear Address Separation (LASS) extension
  ! Implemented 57-bit Linear Address and 5-Level Paging support
  ! Implemented User-Level Interrupt (UINTR) extension
  ! Implemented Intel AMX extensions (AMX, AMX_INT8, AMX_BF16, AMX_FP16, AMX_COMPLEX)
  ! Implemented Intel instruction sets:
- MOVDIRI/MOVDIR64B, AVX512 BF16, AVX IFMA52, VNNI-INT8/VNNI-INT16, AVX-NE-CONVERT, CMPCCXADD, SM3/SM4, SHA512, WRMSRNS, MSRLIST, WAITPKG, SERIALIZE
  ! CPUID: Added Xeon Sapphire Rapids CPU definition
Improved 64-bit guest support in Bochs internal debugger, added new internal debugger commands
Bochs debugger enhanced with new commands (setpmem, loadmem, deref, ...)
Enhanced magic breakpoint capabilities. Refer to user documentation for more details.
Updated Bochs instrumentation examples for new disassembler introduced in Bochs 2.7 release
USB: Fixed/added USB 2.0 Compliance to all devices. Hub still needs a few additions
USB: xHCI: added the ability to have more than one model of xHCI hardware. Currently there are two.
USB: Added experimental MSD UASP emulation
USB: Added OHCI as an EHCI Companion option. Now allows UHCI or OHCI specified as a configuration parameter.
Disk images: Allows large VHD image files
Fixed and enhanced the Floppy Disk emulation, VGA emulation fixes
Expand maximum resolution for Banshee and Voodoo 3 from 1600x1280 to 1920x1440
LGPL'd VGABIOS updated to version 0.9a (several VBE fixes / additions)
Documentation updates and fixes
