Bios Rollback = no Intel ME Firmware downgrade?!

HP Recommended
EliteDesk 800 G5 Tower
Microsoft Windows 10 (64-bit)

Hello everybody,

 

is it "by design" that a bios rollback does not affects the Intel ME firmware?

 

Device: EliteDesk 800 G5 Tower

Bios: 02.06.00 (old); 02.07.01 (new)
IME: 12.0.68.1606 (old); 12.0.70.1652 (new)

 

When rolling back from 02.07.01 to 02.06.00, the IME remains on the (new) version 12.0.70.1652.

Is that the way it is meant to be?

 

Thanks and greetings,
Martin

first of all the Intel ME firmware is a seperate section in the CPU chip, it handles critical functions, and on vpro cpu's also does remote access

https://www.intel.com/content/www/us/en/support/articles/000025619/software.html

 

think it through,................. the Intel ME firmware is updated to fix issues related to REMOTE ACCESS, and critical CPU functions as such you want the latest version and due to this you are not allowed to downgrade to previous firmware

 

while some systems can have a earlier "ME" version forced flashed, this is not recommended and can brick the system rendering it unusable
