Remember that if you trying to continue after triple fault the +# simulation will be completely bogus ! +# +# IPS: +# Emulated Instructions Per Second. This is the number of IPS that bochs +# is capable of running on your machine. You can recompile Bochs with +# --enable-show-ips option enabled, to find your workstation's capability. +# Measured IPS value will then be logged into your log file or status bar +# (if supported by the gui). +# +# IPS is used to calibrate many time-dependent events within the bochs +# simulation.
