+
+The cpufreq-nforce2 driver changes the FSB on nVidia nForce2 plattforms.
+
+This works better than on other plattforms, because the FSB of the CPU
+can be controlled independently from the PCI/AGP clock.
+
+The module has two options:
+
+ fid: multiplier * 10 (for example 8.5 = 85)
+ min_fsb: minimum FSB
+
+If not set, fid is calculated from the current CPU speed and the FSB.
+min_fsb defaults to FSB at boot time - 50 MHz.
+
+IMPORTANT: The available range is limited downwards!
+ Also the minimum available FSB can differ, for systems
+ booting with 200 MHz, 150 should always work.
