HP 1308sl wireless card whitelist

[pma61]

Hi to everyone! A week ago I bought a new wireless card (bcm4311) to use with my HP pavillon dv6 1308sl but I came to the "104 - Unsupported wireless card" error.
I tried to follow the insturctions in this tread -> here , but I think that I have made a bad step and I am at this point: image here
I'm using BIOS version F.46
Anyone can help me?

Anyone can make a bios without whitelist check??
