Jas Sandys-Lumsdaine writes "Bochs 2.0 has just been released - project lead Bryce Denney writes: "It's been a busy 6 months since our previous release! Bochs is now about twice as fast as version 1.4.1. Also, we can now emulate MMX instructions, SSE/SSE2, and even AMD x86-64 instructions if you turn on the appropriate configure options. The emulation improvements have paid off; several people have been able to install Windows XP recently." Excellent stuff."
