 ====== Lenovo T530 Laptop WiFi upgrade ======
-===== Introduction =====
 I successfully installed an [[http://www.intel.com/content/www/us/en/wireless-products/dual-band-wireless-ac-7260-bluetooth.html|Intel Dual Band Wireless-AC 7260 wireless card]] by modifying the whitelist in the BIOS. I've compiled this step-by-step guide with references as I had trouble finding a similar resource online.{{ :projects:t530:programming.jpg?direct&300|}}

 There are two flash memory chips, MX25L6406E (8MB) and MX25L3206E (4MB) (Under frame), according to various resources, I need to flash the 4MB chip. There is also another flash memory chip on the underside which contains the bios settings and password which I don't need to touch.
+There are forums for whitelist removal, such as [[https://www.bios-mods.com/forum/Forum-WiFi-WWAN-Whitelist-Removal|www.bios-mods.com]] but I wanted to figure out how to modify the whitelist myself and to only use the forum as a last resort if I'm unable to make it work myself. (Also, I'd still need to figure out the bios reading and writing)
