Stratix IV incorrect VCM programming

According to Quartus 10.1 devicesupport release notes : 

For Stratix IV and HardCopy IV devices, prior to the release of the Quartus II software version 10.1, Altera incorrectly programmed the VCM (input common mode voltage) of dedicated HSSI refclk pins. The value of 0.82 V as the VCM was chosen, when the industry spec is 1.1 to 1.2 V. To use the previous setting, you must use the .ini file available from Altera.  

 

i would like to use previous setting but which .ini file are they referring to? 

 

Thanks for the help
