It's obvious that he meant Bochs, no need to play dumb.
I just found the idea quite funny that I could have a "BOSCH emulator" in my tool box, right next to my BOSCH electric drill. Especially since OP even used the capitalized spelling from the brand logo.
I'm not trying to be mean here, I genuinely found it funny and tried to point that out the way people usually do in social interactions, rather than rudely responding along the lines of "OMG you made a typo there". I guess that got a little "lost in translation" due to the textual medium and culture difference?
