I updated the latet BIOS F.20 (12 DEC 2011)

I diagnosed that the RALINK RT3090BC4 V20A rev.1.00 half-mini PCI was not working. Before I went ahead to order a new wifi card I was looking for any clue what wifi cards this laptop supports. I couldn't find any information so I ordered a Intel Wireless-N 7260 2x2 BGN + Bluetooth card. I thought that since it's intel CPU , Intel chipset it should work. But to my surprise , I have just received the package from courier went right away to put the card into the notebook, and it doesn't work. I can't even enter BIOS because it's say the following...

"Wireless Module not supported
The system has detected a Wireless module installed in the system is not supported. System halted. Please remove device and restart."

I got a suggestion to write here to ask for bios unlock.I don't know what bios that laptop has. Only the version is available.
