    Bios Locks for making changes to registers




      I am trying to make changes the the Thermal Sensor Register located at IntelQNCLib.c


      The register gets locked after it is set up in Bios so I cannot make changes to it


      I have taken out the lock located in this file but I am still not able to write to the Register


      I can read the register back without a problem using IOCTL through Side band
      from BIOS > kernel space > User space


      I try the opposite for write and it doesn't work
      User space > Kernel space > BIOS




      Is there other locks that I do not know about ?


      Is the way I am writing wrong ?
