Bochs is an easy to use and reliable x86 PC emulation application designed to emulate enough of the x86 CPU, related AT hardware, and BIOS.
Bochs can be compiled and used in a variety of modes, some which are still in development. The 'typical' use of Bochs is to provide complete x86 PC emulation, including the x86 processor, hardware devices, and memory.
What's New in This Release:
· CPU
· VMX: implemented VMENTER to non-active guest state (HLT, SHUTDOWN, WAIT-FOR-SIPI)
· VMX: fixed write of guest segment access rights VMCS fields (32-bit field was truncated to 16-bit)
· CPUID: Don't report Architectural Performance Monitoring in CPUID. Reporting true capabilities without actually supporting them breaks Win7 x64 installation.
· CPUID: Fixed bx_generic CPUID std leafs (all std leafs > 2 were corrupted) - CPUID: Enable all supported VMX capabilities for bx_generic CPUID configuration.
· CPUID: Enable X2APIC support for Ivy Bridge CPUDB configuration.
· Configure and compile
· Enabled VMX compilation by default in shortcut scripts.
· Allow CPU_LEVEL=5 configurations (pentium_mmx and amd_k2_chomper) even when Bochs was compiled with CPU_LEVEL > 5.
· Misc
· Fixes for Bochs port on MorphOS (based on a patch by Thore Sittly): missing functions, byte-swapping and cdrom support.
