[Request] Lenovo Z500 Whitelist Removal

Hello to all,

I've Intel n-2230 wifi card. I want to change my wifi card to Atheros AR9280, but I hear that lenovo do not accept this. Can anybody help me to remove whitelist from my bios ?

Current BIOS : http://download.lenovo.com/consumer/mobi...cn51ww.exe
Info : 71CN51WW(V1.21)

My BIOS Backup : https://www.sendspace.com/file/hwefts

Btw, result2.png says system is x32 but I'm using 64 bit windows 8.1 and mac os 10.10.

Best regards.
Thank you.
