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: 126.96.36.1996 (old); 188.8.131.522 (new)
When rolling back from 02.07.01 to 02.06.00, the IME remains on the (new) version 184.108.40.2062.
Is that the way it is meant to be?
Thanks and greetings,

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
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
