Hello,

First of all, thanks for the great website and for all the free info provided here and also, thank you in advance to anyone that can help me with this issue.  Can someone please patch/unlock these?  These are firmware dumps read with Flashrom directly from the Eeprom chips on a Lenovo T540p.
Once again, any help is greatly appreciated.  TIA!

Ahoy!
I got a Lenovo T540p and i want to remove the whitelist.
I would like to use an Intel AX200 WiFi card as well as other hardware.
So what do i have to do?
I got a SPI progammer as well as a SOIC8 clip.

Top of the day, Mate,
I'm a refurbisher. Two seperate questions:
1. I have about (5) T540p mobos with forgotten supervisory passwords. Otherwise, they all boot and work just fine, but they are worth less. I can dump the 4MB & 8MB EEPROMs. But research has led me to believe that the super p/w is stored on the MEC1633L. In short, can you help me with these?
2. I also have (200) T430s laptops that we will be selling soon. I want to have a set of about (10) different custom BIOS images. THat way a we can also offer our customers BIOS customisations and we'll burn it for him.
Cheers,
Jay

Can someone unlock the attached T540p BIOS? I would like the advanced menu and whitelist removed

[smiglo83]

I have a very important question to ask. Can unlock advanced settings and removal of wifi whitelist be done on stock bios from website?
I don't have any programer available in my country. This is important for me becuse i can't start my eGPU setup with whitelisted slot for wifi card.

Any help would be much appreciated

Hi
it is impossible...you need a SPI-programmer+SOIC8 clip only

[Knogle]

Ahoy. I got the SOIC8 Clip now but there is a problem. It seems like the SOIC-8 Clip is a little bit huge. Is that right?

I got the T540p with OnBoard GPU NVIDIA GT730M

How do you perform the changes? Is there some tutorial? Because i want to start modding UEFIs as well.
I only knew the time of modding simple BIOS ROMs in early 21th century.
