Hi Klem, 

I know that there is a 5 beeps problem due to the changed file size of modded BIOS.

May I know if the guide below is a correct way to create a digital RSA signature?

What I know the procedure of removing whitelist:

Dump the BIOS from T440p => remove whitelist => sign the RSA again to the modded BIOS=> flash the modded BIOS to T440p=> Enjoy

Hi, my T440p (bios ver 2.55) needs your help! Thank you.

1) Please help remove the wifi whitelist for any future cards

2) Do the RSA signature again to avoid 5 beeps problem

 

Thanks! Klem

      In this thread you can post your requests for Lenovo ThinkPad L440.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
