In addition to this, you # may configure a math emulator (see above). If your machine has a # hardware FPU and the kernel configuration includes the npx device # *and* a math emulator compiled into the kernel, the hardware FPU # will be used, unless it is found to be broken or unless "flags" to # npx0 includes "0x08", which requests preference for the emulator.
