I don't have that entry and it seems to be a mystery one.
This guy has 2 identical T500 and one dose not have AMT

Nice tool but it is not up to date with an T500 entry as you say!


I'm more convinced now that it is AMT and that I need to get it turned off.

I did a session checking the DHCP Request when the cable is inserted.

- Power on 
- Boot XP - No Request Until XP ready.
- Restart - Request start when XP shut down graphics.
- Reboot - Requests
- Enter Grub - Requests
- Boot Fedora - Requests
- Fedora up - No Request.

In this case XP shut down trigged the plugg Requests.
So either XP of Linux shutdown stasrt the request.
One thing notice is that the DHCP Transaction number for
XP and Linux has format 0x12345678 and Host option.
The one comming from AMT has format 0x123456
and no Host option.

The bottom line is that DHCP Server gives different IP
according to the Host name (same MAC). 
This is right but there is a fault when the different hosts
are mixed frequently. Each MAC/Host dose not get the
same IP and thing start to get messy.

Have to look into that and leave AMT for the moment.

/Thanks
