I know my BIOS is RSA signed, and if it brick I need to remove CMOS battery. I can do that, so please continue.

Hello there,

I have a HP Pavilion G6-1095st, and I need to change Laptop's wireless card.

I need to chage Laptop's wireless card because it's very poor and only give 72mbps max speed.

I need a modified bios, but HP rsa signed my bios and no one dissassembled his/her laptop there are no bios mods available.

But, I already disassembled it many times for cleaning, so removing CMOS battery is easy for me.
