  1. The cpufreq-nforce2 driver changes the FSB on nVidia nForce2 plattforms.
    2. 

  2. 

  3. This works better than on other plattforms, because the FSB of the CPU
    4. 

  4. can be controlled independently from the PCI/AGP clock.
    5. 

  5. 

  6. The module has two options:
    7. 

  7. 

  8. 	fid: 	 multiplier * 10 (for example 8.5 = 85)
    9. 

  9. 	min_fsb: minimum FSB
    10. 

  10. 

  11. If not set, fid is calculated from the current CPU speed and the FSB.
    12. 

  12. min_fsb defaults to FSB at boot time - 50 MHz.
    13. 

  13. 

  14. IMPORTANT: The available range is limited downwards!
    15. 

  15.            Also the minimum available FSB can differ, for systems 
    16. 

  16.            booting with 200 MHz, 150 should always work.
    17.
