Note: Firmware versions of Intel ME 3.x thru 10.x, Intel TXE 1.x thru 2.x, and
Intel Server Platform Services 1.x thru 2.X are no longer supported versions.
There is no new general release planned for these versions.
Recommendations:
Intel recommends that users of Intel CSME, Intel TXE, Intel AMT and Intel SPS
update to the latest version provided by the system manufacturer that addresses
these issues.
The Intel AMT SDK is available for download here .
Intel has issued a Product Discontinuation notice for the Intel DAL SDK and
recommends that users of the Intel DAL SDK uninstall it or discontinue use at
their earliest convenience.
