[REQUEST] Lenovo IdeaPad P400, P500, Z400, Z500 (71CNxxWW) Whitelist Removal

[sovem]

If someone can remove the bios whitelist for me it would be much appreciated! I have the P400 Touch and I believe it runs the same bios as the Z500. I want to use an Intel Wireless-AC 7260 with these hardware IDs. This WiFi card has Bluetooth built in so I am unsure if there is a Bluetooth whitelist also.

Thank for your for modded bios! Whitelist is removed and computer booted with no problem with new WiFi card but for whatever reason Bluetooth is not detected.

Please post PCIs of original and new card.

This is exactly what happen after I had my Z500 Touch bios modded more than a month ago. Although, I was able to restore my bios to manufacturer's condition, I'm still interested in the solution to this problem.

Please post PCIs of original and new card, too.

Sorry didn't quite understand earlier the PCI requirements. I no longer have the original modded bios installed since I updated to a new one I'll just wait for Amoeller's case result before making a new mod request later.

Hi,

at the moment many users want to use another e.g. wlan card and are receiving an error: Not supported device. This is because of a whitelist at the bios that contains hardware ID's of special OEM vendors that are allowed to run. Others are restricted and don't run.
This is annoying and IMHO a bad marketing politic.

There are 2 general ways to break this restriction:

1. Add your card's IDs you have bought to make it run
2. Disable the check code.


The specific byte sequence (your vendor ID, device ID, sometimes the subsysID) is not found at the biosimage. It’s almost always compressed in a module.

General steps to mod, no matter what bios:
-decompose the bios into its modules and decompressing, at least one module.
-search through the modules for the bytes sequence of your currently used card. Note it’s stored like that:

PCI\VEN_8086&DEV_4237&SUBSYS_12118086&REV_00

Means:
Vendor: 8086
Device: 4237
SUBSYS: 12118086

Stored at whitelist like:
86 80 37 42 86 80 11 12

How to obtain the IDs:
1. Remove existing wireless card from laptop, leave the access cover off.
2. Boot laptop and enter boot selection screen. Press F8 therefore.
3. Install new card (whilst laptop is running), no need connect antenna wires.
4. Boot into windows and new card will appear as unknown device.
5. Now you can obtain exact ven, dev & subsys id's from device properties

-patch an unused ID sequence with the ID sequence of your new card. Correct sums if needed (HP’s own bioses)
-rebuild the biosimage.



Instructions for efi, Insyde, Phoenix bioses:

Use andy's Phoenix tool version 1.55 or above.
Tick No SLIC and Allow users to modify other modules.
Open the bios to be modified. The tool extracts the modules into the dump folder and pauses.
Now search for your byte sequence in the dump folder. Or try to find the whitelist code, or modify what you need.
Save your modifications.
The tool will notice about the changes and reintegrate the modified module.
Please note we don’t use the tool to SLIC a bios, but to decompose the modules / rebuild the bios.

Example and how to apply Zender's great patchtool for Lenovo phoenix bioses:

That way you may edit any module. It will result to unable to reintegrate if its new compressed size is bigger and hence it doesn't fit to its original offset before. You may gain space when editing another sequence to the same ID string (more compressible).

I hope that I can soon take care of this thread. At the meantime, I would be happy if anybody that is familiar with whitelistmodding is posting results / instructions..thanks.

This subject is at the start of development.

Question:
So in this mod of Amoeller's bios the whitelist is not remove but the new card is added to the list? If yes, what if Amoeller decide to use another card, do you need to mod again the bios?
