Intel 945G based mainboard D2156: Component change necessary for full support of Intel®  
Pentium® D processors („Presler“, D0-stepping), based on latest Intel recommendation.
Some customers have observed critical system instabilities when using certain Pentium® D
processors on D-0 stepping in combination with i945G based mainboards. These failures are
not observed on other Intel chipset based mainboards.
Intel has evaluated a workaround that will be implemented with minor hardware changes for
D2156-S21.  
These changes will have no impact on other processors supported on Intel 945G chipset.
