How to use IVPREP and 1VYRAIN and Disable Intel ME on a Lenovo x230

[catacombs]

This is where I was attempting something similar.

Anyone with recent experience out there rolling back BIOS on X230

Finally found it. I have not used DOS in like fifteen years. Start Command, and cruise to where the extracted folder was, in Downloads in this case. Click on downgrade.bat. BIOS says it is now at 2.60. onto to 1vyrain.
