Please make sure that BOCHS is configured properly:Ģ.
Now, when I repeat the steps above, it tries to launch the Bochs Debugger (I just get a busy icon, so I guess it is attempting to launch the Bochs Debugger) and after few seconds, gives me the warning: "Failed to run bochs with: C:\Program Files (x86)\Bochs-2.6.2\bochsdbg.exe" -f "C:\shellcodes\shellcode.bochsrc" -q Stephen Kitt <> bochs (2.6.10+dfsg-1) unstable urgencymedium New upstream release update patches, in particular - remove the QEMU BIOS patches, which conflict with 2.6.10 and are no longer needed (QEMU now uses SEABIOS, not Bochs BIOS) - remove the USB patches, merged upstream.![setting up ida and bochs 2.6.9 setting up ida and bochs 2.6.9](http://www.dgaequipment.com/upload/image/20151226/calculate-ON.jpg)

SETTING UP IDA AND BOCHS 2.6.9 INSTALL
If you had Bochs install Start Menu shortcuts like I recommended, there should be a shortcut to 'Bochs 2.4.5 Folder' you can click on to find it. The Bochs default install directory is C:\Program Files\Bochs-2.4.5. Follow exetools on Twitter and send me a message, I will choose whether. Next, put this Bochs configuration file into Bochs' directory.
