Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org There is some documentation on serial #s (the stickers not the electronic IDs) in the Intel literature. In my "Intel Workstation SDV, A1 Stepping Processor Replacement" manual there is a section on page 20 entitled "Identification of Upgrade Processor Stepping" with a table mapping the 4 digit postfix to the A2 and A3 stepping. This also includes some comments about the state of software revision detection. I do not know if this info is truly public, so I have not copied this info here. Perhaps someone from Intel would like to comment? These postfixes are of the format Q[letter][number][number]. I would assume there is a complete table available someplace that would include A1-A3 and B0-B1 stepping maps, but I have not seen it. The only reliable option I know of is to open a QuAD ticket on the system and ask Intel.
