No AMT message

[kroeckx]

When I run this, I get:

Error: Management Engine refused connection. This probably means you don't have AMT

It would be helpful to put in the README.me that that is a possible output and what that means, and why it's different than the Intel AMT: DISABLED output.

The mei driver is loaded, lspci outputs:
00:16.0 Communication controller: Intel Corporation Wildcat Point-LP MEI Controller #1 (rev 03)

dmesg doesn't say anything about mei.

I think I don't have an AMT.

I'm using this BIOS:

Version 1002 2018/07/06
8.76 MBytes

PRIME Z370-A BIOS 1002

seen here: https://www.asus.com/us/Motherboards/PRIME-Z370-A/HelpDesk_BIOS/

I don't remember anything with Intel Management Engine in BIOS, but I seem to remember something about AMT, so I'll try to look that up after reboot and update this.can't find anything about AMT either!

I faced the same issue.

Motherboard: Intel DH61HO
Processor: Intel Core i3-2100

My BIOS shows iAMT, by the way, though I cannot do anything to it.

Yes, getting
Error: Management Engine refused connection. This probably means you don't have AMT
on 2 PCs:
ASUSTeK COMPUTER INC. H81M-K with Intel(R) Pentium(R) CPU G3240 @ 3.10GHz
and
MSI E3 KRAIT GAMING V5 (MS-7A43) with Intel(R) Xeon(R) CPU E3-1270 v5 @ 3.60GHz
The MSI Krait has no AMT or ME mentioned in bios, nor in manual (PDF).
