Intels Steve Peterson, Director Chipset
& Software Marketing, stated "[the] 3-series
chipsets have been designed and optimized for Core microarchitecture
Since Intel wants transition its whole CPU-lineup
to Core microarchitecture by the end of Q2, the
Bearlake-chipsets are designed to match up with those CPUs. As a
result, Intel only validated these 3-series chipsets with Core-based
However, there is still a chance to
make this combination work, as Intel is not aware of any specific
incompatibilities between 3-series chipsets and Netburst-based CPUs.
To clarify, Intel simply didn't validate this combination and thus cannot
officially support it -- at least that's what the corporate brass is stating.
Peterson added, "Although, we are not aware of any
incompatibilities with Intel’s Netburst Microarchitecture based
CPUs when used with Bearlake chipsets, we have not validated this
combination and our design guidelines restrict the Bearlake family
boot function to Core Microarchitecture and beyond … Some customers
may not follow all of our guidelines and may allow for the Netburst
Microarchitecture based CPUs to boot and run. In this case, the OEM
would guarantee the reliability associated with this unvalidated
In a nutshell, Intel design guidelines
restrict the boot function of the Bearlake family to Core
microarchitecture CPUs and future models. However, OEMs can implement
boot-code for Netburst-CPUs and support them on their behalf.
