In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p / E440 / E540. If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, and sign unlocked bios with digital RSA signature (to avoid 5 beeps problem), 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.
