Hi~~friend!
Because this bios’s micro code module is “C512C56D-0A81-47C3-81AE-E0A10576B778_0_374”,not a normal “17088572-xxxxx”,so you can’t watch “cpu path” normally on mmtool aptio interface.

How to modify it??
Although we know micro code module was “C512C56D-0A81-47C3-81AE-E0A10576B778_0_374”,but i also can’t found it on mmtool aptio.(Maybe my eye has problem)
So you need use “PhoenixTool” to extract all of efi module and find this micro code module then modify it by a hex edit tool.
After you modified finish,you need to package it again by PhoenixTool.
Here is currect micro code on this bios.
