      the function ADL_Overdrive5_FanSpeed_Get returns the code error "ADL_ERR_NOT_SUPPORTED   -8" (using Catalyst 12.4), as in those posts: http://devgurus.amd.com/message/981882, http://devgurus.amd.com/message/984820.

      The doc says "ATI OverDrive™ Version 5 API supports the following operating systems:

          Linux 32 and 64 bit distributions ", and the "AMD_OverDrive_Utility_AMD.COM_Release_Notes.pdf (version 4.2.1)" says it supports the AMD 770 chipset (I have a HD4850) but apparently it is not.


      1. Is it planned to add the support of those functions on those systems ?


      2. Is there another API for controling the fan speed ?


      3. What does AtiConfig use for this (something called PPLIB ? Is there a way of using this "lib" ?)


      Thank you ;-).

          Here's the reply that I got from an AMD person.


          "If the system’s VBIOS/PPTable does not config internal thermal controller type, they won’t be able to read fan speed via OD5 interface.


          Users can post the VBIOS information so that  I can help check.  CCC->Information->Hardware."
