What is Me Region
ME (short form of Management Engine or Manageability Engine) is a drive stored in BIOS and only on recent Intel platforms (Core i). Secondly, ME is used by first integrated into the Network Card and then transferred to Chipset (GMCH, then PCH, and MCH).

How Does ME Region Work With PCH
When booting the computer, ME Region will receive all information from PCH to compare with ME Region information stored in the BIOS. So even if you save this BIOS for other computers even with the same model, PCH within also been replaced, there are still chances that errors arising from ME Region.
The reason is that the information from the new PCH does not match ME Region stored in the BIOS. Thus, ME Region is not faulty but ME Region is not working or not working well because the information does not match when PCH is replaced with a new chip or from another main unit. There are also some cases where the ME Region.
