For all X41 Tablet users who want to get rid of error 1802 (and perhaps also 2010): I also received the the crisis diskette error while flashing BIOS, but I saw that most of the blocks were already written, so I gave it a try. I replaced my Intel 2915ABG with a new MiniPCI Atheros N WI-FI Card and guess what: IT WORKS!!!! No more "error 1802 unauthorized network card is plugged in" on my Lenovo X41 Tablet. Thank you for this great MOD!!!
