If you use other versions of Bochs, you can get some problems...

Known issues:
1. We noticed some bugs in IDA debugger while jumping to the long mode, but Bochs built-in debugger works just fine. ;)
2. Bochs 2.4.6 is not able to boot the system after infection due to its bugs! (The task is still solvable)
3. There can be errors in OS after booting infected system. Use power off/power on instead of reset. (Sorry, we didn’t have time to fix all the bugs!)
