    The laptop is a HP DV7T-7000 series and it has a Intel Centrino Wireless-N 2230 card installed.

    Unfortunately, i'm rather new to the idea of having to mod a bios to get around a "white list" so i dont know how to find the PCIID that you're asking for. I was just curious to see if the 7000 series had similar undocumented WLAN adapters on the white list as the DV7T-6000 that you found for OhioLefty a few pages back.

    From another forum, here's the info for the ralink rt5390r that can also be installed on the Dvxt-7xxx line:

    PCI\VEN_1814&DEV_539A&SUBSYS_1839103C&REV_00
    PCI\VEN_1814&DEV_539A&SUBSYS_1839103C
    PCI\VEN_1814&DEV_539A&CC_028000
    PCI\VEN_1814&DEV_539A&CC_0280

    Is it possible to remove the whitelist, because, say, I have an Intel 6235 wireless card lying around. I'd love to use it in my laptop (same as the other guys')

    If this is true (I've got a 6235 wireless + bluetooth card lying around), this is very good news indeed. Now we just need to unlock the bios features.

    Hi Yen,

    did you find out if BIOS is decrypted in the chip?
    I want to help with anything RSA related. These f**kers...

    I looked through the forums but can't find anything related to RSA flashing.
    I saw something with a patched insyde flasher dll tool?

    I have a dm1-4151nr and I like to help.

    Please let me know if you don't have time. I am busy, too. Thanks,
    - S

    I want to replace the wlan card in my notebook because its destroyed. My notebook does not start with the new wifi card because "it is not supported". Please help me to remove BIOS whitelists.
    - Manufacturer: HP

    - BIOS version: F.48
    - BIOS download link: sp55430.exe (it's RSA signed BIOS)
    - Old wlan card type: Ralink RT3090BC4 V20A
    - New wlan card type: Intel WiFi Link 5100 (512AN_HMW)
    Thank you for your help!

    No that's not enough... In fact that's not it at all. The .DEC .SIG files are only
    necessary if you want/have to use the original insydeflash.exe (or the UEFI flasher
    for recovery). If you really want to know if your bios image itself is signed you have
    to look decompose the bios (with andy's tool) and look for a rsa-sha1 signature.

    really ? ok then use hexedit on the .fd not DEC.. then use it on the fd.DEC
    notice a BIG DIFFERENCE ???
    also why is RSA.sig made if "its NOT it at all" ?
