    3538The 47M15x and 47M192 chips contain a full 'hardware monitoring block' 
    3639in addition to the fan monitoring and control. The hardware monitoring 
    37 block is not yet supported by the driver.

    39 FAN rotation speeds are reported in RPM (rotations per minute). An alarm is 
    40 triggered if the rotation speed has dropped below a programmable limit. FAN  
     42Fan rotation speeds are reported in RPM (rotations per minute). An alarm is 
     43triggered if the rotation speed has dropped below a programmable limit. Fan  
    4144readings can be divided by a programmable divider (1, 2, 4 or 8) to give 
    42 the readings more range or accuracy. This is important because some FANs 
    43 report only one 'tick' each rotation, while others report two - making 
    44 all readings twice as high. Not all RPM values can accurately be represented, 
    45 so some rounding is done. With a divider of 2, the lowest representable 
    46 value is around 2600 RPM.
