I bought a Z240 Workstation on Ebay. On Boot it had an error on bootup.
"(A7) Me FW Downgrade - Request MeSpiLock Failed"
Researching this error led me to update the BIOS to version 1.78a
After the installation of this BIOS Update through HP I received the above error in addition to:
"Error sending End of Post message to ME: HECI disabled, proceeding with boot!"
Unfortunately, a BIOS restore is not possible. I formatted the drive, and reinstalled windows.
All of my firmware is up-to-date through the drivers available on the website.
I have disabled Intel AMT, which I don't need anyway. That has removed the "(A7) Me FW Downgrade - Request MeSpiLock Failed" error. However the "Error sending End of Post message to ME: HECI disabled, proceeding with boot!" error still exists.
The Intel Management Engine Software V11.0 software will not install saying it's not for my platform.
I would appreciate any help available.
