Lenovo z50-70 Bios without whiteliste

Hey.
Does anyone have anything for Lenovo Bios without a whiteliste?
Or maybe there is someone who can change the Bios?
I wanted to change to a new WiFi card and it is not listed.

Bios Version:   9BCN91WW
EC Version:     9BEC91WW
Lenovo SN:     YB06609958


Thank you in advance.

PS Sorry for my english.
