Updating bios bin
However, since we cannot always find the latest MEI-Only Installer, it is advised to use the "INF for manual installation" in case its version is newer. The SOL "driver" listed above is part of the complete Drivers & Software packages found at section A3.
A newer Drivers & Software package has newer Software but the actual SOL "driver" may still be an older version.
The ME firmware is neither static nor identical across different systems.
Its code at the Engine region is always Configured by the manufacturer (OEM) as explained at Section A of the Clean Up Guide.
Thus, they can neither be opened nor configured by Intel's Flash Image Tool.
All (CS)ME 8.x or newer firmware are defined by a Version Control Number (VCN) like 1,2,45,193 etc which is used to control the possible upgrade/downgrade paths provided by Intel's FWUpdate tool.
The VCN gets incremented if there is a security fix, a significant firmware change or a new feature addition.
To allow quick and effortless on-field updating of the ME firmware, Intel provides a tool called FWUpdate.
Update images (UPD) are partial Firmware Regions which contain only ME "CODE" without any "DATA" (read Section A of the Clean Up Guide).
