. Well, if you don't have access to some crazy hardware flasher then you probably want to attack HP's RSA-SHA1 validation code for the DxE image. As far as I can tell, it's the weakest link and it is actually all you would need since whitelist and the bios setup utility is stored there [bios setup utility = the one that opens when you hit F10 at boot]! However, with the lastest bios releases HP has "strengthened" that link (no idea if they are reading the boards or not, or maybe they got a lead from the people who bricked their laptops and then returned it). About the keys: I'm not aware of any leaked private keys. Maybe some of the Russian or Chinese folks know more but it's difficult to contact these communities. I'm still looking though, because once we got one, we can complete hewprsa and integrate it into AndyP's tool. Another possiblity would be: adding support for the dv6's ec to flashrom. However without a laptop "donated" to science to some of the flashrom gurus I don't think it will happen in the near future.
Really very good and exaustive explanation. Thanks. I hope in something of good for the future buddy,
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.
Can someone please have a look at this bios as well? Apparently this ones RSA signed as well -Manufacturer: HP -Model: 1469 -Bios revision: F.27 -Bios Type: Insyde -Bios Download Link: sp56058.exe (please google, cant add links to this post :/) -Current card: PCI\VEN_1814&DEV_3090&SUBSYS_1453103C&REV_00 If possible I want to add intel 6230 to the whitelist. -Card to be added: PCI\VEN_8086&DEV_0091&SUBSYS_52018086&REV_34
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
Hello Guys, 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 - Type: G62 - B40SH - 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!
