Hi guys,

Looking to get my BIOS hidden menus unlocked, it's a ThinkPad T450s, I've dumped the ROM with the CH341a hardware tool. 

Which brings me to an issue...the BIOS chip in my laptop is a W25Q128FVSQ, the closest chip profile available in the flash/dump program is the W25Q128BV, I am unsure if that brings an issue or not with the BIOS dump or BIOS flashing, it seemed to dump fine. Any thoughts?

Anyway, here is the BIOS:

https://www.dropbox.com/s/vkdboqnp3zhwk6t/DUMP.bin?dl=0

Specifically looking for the menu that allows me to change the Pre-allocated DVMT values (I have a IdeaPad Y560P with an unlocked Phoenix BIOS that has this option - so I figured there's a good chance that it is available.) All menus unlocked would be awesome, though, if you can.

I'm definitely willing to donate, I'm not the richest man in the world, but I will give what I can.

Let me know if you need anything else.

Thanks guys!
I will give a look quickly !
I am sorry mate your file is crapped It has to be 16384 KB and is only 128 KB
It has only Descriptor an not all ME Regions !
You have to read the Eeprom Chip again and make a good Dump !
Let me know
Regards
Hi mate,
Use this tool run It as Admin and upload here the result file :

Use AIDA64 tool too (cracked version to get FULL REPORT) and upload a Report too

let me know
Regards

P.S. I will get your Bios Backup to make the Modifies !
Your Bios Backup would seem like this (Extracted version 25) Bios Region Only and then
You will get Descriptor + ME Regions too into your Full Dump Firmware file !

Look :

That contains dumps from both tools, the report, and another dump I made with the linux CH341A tool. The size checks out now.

It seems as though the Windows tool was not using the proper size for the BIOS chip I have...the linux tool does, however.

Thanks again!
As a side note, the Universal BIOS Backup dump and the ch341a dump have the same size, but a different checksum. I've read that on the latest Lenovo laptops (I believe from some of your posts), that a proper BIOS dump cannot be obtained without a eeprom dumping tool, such as the ch341a I have.
I got an error on this file during decompressing so please upload It again CH341A Tool Dump !
I checked the files and We got the Bios Region Backup so now We need the Firmware Dump
to Patch It Wink
