Please whitelist my bios for a Lenovo IdealPad Z400 Touch, so that I can upgrade the WiFi card to one currently unsupported.
Here's a dump of the current BIOS file:

Hi..

My Lenovo Z500 wireless card is broken and cannot be replaced due to the bios white list.
Kindly unblock my bios and remove restrictions from the white list ...
