Hi Klem!

Thank you for your reply!

I bought two network cards, ax200 and ax210. In fact, I only use one network card at a time, but I don't know which one I will install on my t440p in the end, so I hope to get the adaptation of two network cards

Hi!

In Lenovo ThinkPad T440, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread.

So, for creating backup (dump) of bios you need to use hardware SPI programmer only. Just read carefully the first post on the first page.

The battery type limit is in the EC firmware (not in the bios), but I don't work with EC firmware.

Hello Klem,

 

I was wondering if you could help me remove the whitelist on the bios of my T440p.  I've dumped my BIOS, and it is here

 

I've tried to mod the bios myself, but after uploading my modded bios, I've run into the 5+5 beep error, and the laptop will not boot up.  If you can work your magic on the original dump, I would very much appreciate it.

Hi Klem,

 

Please modify my T440P bios version 2.56 with all your mods.

 

Here is the link:

https://www.dropbox.com/s/ryhd5fdol7mq485/bios.bin?dl=0

 

I'd like to be able to install any wifi adapter, access the advanced menus, and not have any startup beeps.

 

Thank you.

      Clevo P150SM(-A) Prema Mod
      By Zauih840
      Hello, as the title states, I would be very happy if someone could give me the link to the mod, apart from that, what version should I install?, as I've seen that some models have v1 and v2.
      My other questions are: what do I have to do to install a new GPU?, (9xx series)
      And what mods do I have to use to have a 10x0 series (and which are compatible).
      I have the Clevo P150SM(model)/P150SM-A(product code) (2 models on the sticker) with stock bios (it says copyright 2012, so I guess it's the 1st version) with a 4710MQ and 870M.
       
      I would be very pleased if someone could hand me the link.
      Many thanks in advance.

      Lenovo B570e - help with unlocking the whitelist
      By biuro74
      Hi,
       
      So I've landed here to get some help with unlocking my old laptop. I must confess I've done few mods before, but it was on PCs, so was a piece of cake - adding Xeon to supported CPU models, or updating OROM to get a system boot from RAID SSDs. But now I'm trying do "the same" with laptop first time and this is a nightmare, mostly due to multiple BIOS vendors/methods, each of which requires own tools, some works with older revisions, some don't, some require 32-bits, some don't, and all YT examples being done using various configs = so in the end: a mayhem.
       
      My laptop config is:
      Lenovo B570e, i5-2520M, 10GB RAM
      BIOS: 44CN43WW (latest, unmodified), SMBIOS 2.6
      Phoenix/EFI SLIC Mod indicates it is an EFI/Insyde BIOS, but entering the BIOS I've got "Phoenix SecureCore Tiano" info
      WLAN: original damaged, a replacement (by chip) doesn't allow laptop to start - Error 104 Unsupported wireless network device...
       
      All I've found so far was:
      * Universal BIOS Backup Toolkit 2.0 - to make a BIOS dump file (succees)
      * UEFI Tool - to load dump file, search required module and extract it (success)
      * WinHex - to search an assembler code boundaries, and extract it (WinHex will not save edits = unregistered version), so semi-success
      * Hex Editor Neo - to disassembly code, and probably make changes (so far: in progress:))
       
      And I've stopped at searching the JZ/JNZ mnemonics, probably this is because I've got wrong code boundary (from WinHex), which gives improper disassembled program in preview pane. What I'm looking for is a loop, which I try to obey - regarding to some "popular" links describing this method (unfortunately I can't follow these instructions 1:1 as some programs don't work as supposed and crash - like WinHex, yup, some don't work at all and I need to use different tool).
      One more frustrating thing is I can't find proper tool for final stage - which is good (working) flasher. I can't remember how I've reflashed BIOS previously - must have been years ago - but now PhoenixUEFIWinFlash makes a BSOD (original, executable BIOS downloaded from Lenovo support website uses this program, which shows its GUI for a moment and makes BSOD), and "external", latest Phoenix UEFI WinFlash program doesn't want to work properly at setting up stage. Probably I will have to use phlash16 and FreeDOS, but will see at the end, when I have modded BIOS completed.
       
      Any suggestions (or even better - some ready, modded file), please ?
       
      Thanks in advance for any help, I appreciate any clue.
