[REQUEST] X1 carbon 2nd Gen Whitelist

Hi,

could anyone help me remove the Whitelist for this X1 Carbon 2nd Gen BIOS? I've managed to remove it, but on every boot, the laptop gives off 2 x 5 beeps, then boots normal (and recognises my custom cards). So if anyone knows how to perform this modification without getting the beeps, feel free to help or give me pointers! 

This is a very early bios version as I don't currently have a battery to update to a newer one. Attached is a stock version of my ROM chip, that I read out with an SPI reader/writer.
