Hello everyone! 
I am very new in bios modding and recently acquired a very cheap brand new ThinkPad, I recently tried to install a WWAN card (Sierra Wireless AirPrime EM7355) and got the infamous 1802 error that prevent the laptop to boot, the whitelist is looked up by the bios even while the pc is running (yeah I tried to hot plug the card and it worked fine for a minute until it got blocked again by the bios) I really want to try to mod the bios by myself because I think it would be very educative for me, but there's only few guides / tutorials on internet working for me, what I did is extracting the binary file from the bios chip, and open it with UEFITool and there's my issue, when I search in UEFITool for ''Unauthorized network card is plugged in" I get 3 or 4 results and end up with 3 or 4 PE32 files, and it is getting me really confused, which on should I mod ? all of them? also i opened them with IDA Pro and i do find the error message but i struggle to understand what's going on in there because it is really different from the tutorials / guides.
Can anyone here take a look at the binary file of the bios in attachment and help me better understand what's going on in there? it would be very very apreciated !
