								>      Bochs does a very good job in emulating an x86 compatible computer, however,

							 | 
						||
| 
								 | 
							
								      (BIOS) function call or (hardware) device. Thus, in case something unusual
							 | 
						||
| 
								 | 
							
								      happens, either a not-so-common call to some (BIOS) function or device by
							 | 
						||
| 
								 | 
							
								      some software running inside of it, Bochs has two possibilities to react:
							 | 
						||
| 
								 | 
							
								      If the command doesn't look important (mainly happens only to non-implemented
							 | 
						||
| 
								 |

								      and the emulation continues. If, however, the command looks important, Bochs
							 | 
						||
| 
								 | 
							
								      panics, because the software being emulated might depend on the successful
							 | 
						||
| 
								 | 
							
								      execution of the given instruction or behaviour of the device.
