Question about retrieving (not removing) BIOS whitelist

[rottenegg]

Hi people,

I have a BIOS dump of a Lenovo Y50-70 (4k screeen version), obtained following this guide. Now, as the title says, i want to search for the cards in the whitelist. 

First I checked the file mentioned in the guide with hex editors and IDA Pro, but i could not find anything related to a Device Id or Vendor Id for Realtek, Intel, Broadcom, Atheros cards.

Then I tried to search in any file with the following command:

Code:

for f in $(ls); do xxd -u $f | grep -C 5 "${VENDOR_ID}"; done > xxd-search.txt

but the only things i found was PCI entries for Intel Thermal Framework devices or Realtek audio cards.

Do you have any suggestion? I don't know where to look, or which tools should I use to retrieve this whitelist. Thanks in advance!
