Quote:After an extended period of back and forth with Intel, we have confirmed that the existing B-1 stepping chips do suffer from the LPC bus degradation issue, which can be rectified via a firmware update. This issue is classified as Errata APL47, as listed here (PDF). When the B-1 Stepping is used in accordance to the published specifications and design guidelines, it meets PC Client Usage requirements.
The new F-1 stepping products have the LPC bus degradation issue fixed in the silicon and will be available for order for 15 years.
We've amended the article below to include the new information and a portion of the errata/fix description.
