Hello,

While upgrading my old Lenovo z500, I prepared a new wi-fi card (WIFI6E MPE-AXE3000H).
It is blocked in bios so I had to remove it. Now just surfing on LAN.

Can somebody kindly help me with a whitelist removal + advanced menu bios?

Bios data

date: 07/12/2013
size: 4608k
mode: UEFI
backup: google drive (using Universal BIOS Backup ToolKit 2.0 on Windows 11)

Thanks a lot!

Hi, im new here. i have a lenovo Z400 laptop i would like the whitelist removed please.

below is the dump of the 2MB rom chip (U6), which is the one with the configuration data. (the other 4MB rom chip, U5, only has the boot logo's on it)

Please help with this, i've scoured the .bin for about 3 hours and i'm unable to locate the subroutine that handles the wireless card verification.
