Bochs/bochs/main.cc
Bryce Denney d0f1caa404 - turned rom address and vga rom path into bx_param_c parameters, so that
now the whole "Bochs Memory Options" menu uses new style parameters.
  The next step is to remove the hardcoded stuff that generates and runs
  this menu, and replace it with general menu building code.  All you should
  need to create this menu is the string "Bochs Memory Options", and the
  IDs of the bx_param_c options that should appear on the menu.  The
  bx_param_c structure for each parameter tell what type it is, how to
  display it, constraints on the value, what to do when the parameter
  changes.
