Intel AMT gone from Bios after WiFi card replacement with vPro part.

2018-11-13, 22:03 PM

Hi all,

My T460p came with a 8260NGW, FRU 00JT530, and it is a vPro part.

I had it replaced with a 9260NGW, but while the card worked fine, the AMT menu (and prompt for the configuration shortcut at boot menu) disappeared.

I did a bit more research and found there are actually two different FRU's, one is vPRO (01AX771) the other isn't (01AX769 ).

The first 9260 was indeed a non vPRO part and as such I replaced it with my 8260 (after my motherboard was replaced) while I ordered a vPRO part (01AX771). AMT was back in the bios menu with the 8260 (note: also new motherboard), but as soon as I replaced it with the 01AX771 part (vPRO) it is gone again.

Anybody cares to explain or advise on the topic?

 

Thanks!

Howdy,

 

I can't explain or advise.  What I can do is guess.

 

I've heard from others that the WLAN whitelist still exists in BIOS, but isn't enforced as a boot-time lockout.  It is possible that it is used to distinguish vPRO from non-vPRO cards.  This instead of probing card capabilities somehow.

 

Just a WAG... and not very helpful...

That is my guess too, that there still exist some sort of whitelist, but I cannot establish what kind of whitelist that is and what it does.

 

Because the part I now use is a vPro part, but still, it is not "allowed" to function as vPro. Also what kind of whitelist removes the AMT menu and the Ctrl+P shortcut from the bios permanently(?) if you swap the original card with a different one. Because there are reports that even after the original card has been restored, the AMT menu does not reappear.

 

Is the card S/N linked to the motherboard bios somehow? If that's the case I missed out on the opppotunity, as I had my motherboard replaced and at the time this happened I only had the original 8260 card available. So when the technicial entered my laptop's S/N to the bios, maybe (and this is a guess) the bios reads the S/N of the wifi card at the time and sticks with it. 

 

Who knows? Anybody from Lenovo?
