IBM Thinkpad X31 - 1802 unauthorized network card error - solved

If you are getting this error during the Startup of your ThinkPad: 1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card. You have most probably a 3rd party WiFi Card installed. In this Video I will perform a hack to use any third party WiFi or Network Card in a Thinkpad. That is esecially useful because the ThinkPad X31 was delivered with a particular weak WiFi Card. You need this Software: This hack is confirmed working on: A31, A31 2652-Q3U, A31 2652-1U6A31p, A31p 2653-CU5, A31p 2653-R3UG40 2384-EHUR40 2682-HU2, R40 2682-K2G, R40 2681, R40 2896-GZUR50 1830-48GR50e 1834-BZGR51T30, T30 2637T40, T40 2373, T40 2373-8CU, T40 2373-94G, T40 2374-GG2, T40 2374-DG1T41, T41 2374-7JGT42, T42 2373-BX9T42pX24X30X31, X31 2672-U31X40. Please post it here, if hack works with other ThinkPads.
