[dimpan]

Hey guys, just bumping this because i have the same system

Lenovo M93p Tiny model 10AA

I have uploaded the BIOS to my google drive here ;

https://drive.google.com/open?id=1A1DAQb...B6sMbXdPEL

However it can also be downloaded here ;

Is it possible to allow any mini pcie card?

thank you!

I honestly can't believe this worked, but it did. Thanks so much for figuring this out!

Hello I would like to replace the original wifi card of my lenovo m93p (Wireless N 7200HMW) by a newer supporting AC (wireless AC 7260 HMW).
I'm trying to download the backuptools from https://rghost.net/7GBZt7FVt, but it says Access to the file is restricted even with a registered account.
What else do I need ?
Thank you for your help

Hi i know that this is an old thread but could you be a bit more specific on how did you invalid your SN and model? i need to do the same to be able to use a wifi card that i already have from my laptop on my m83 tiny. i am just assuming that since bios update is shared between m93 and m83 your method should work on my machine too

Very very Thanks

Hello.

Same here, would like to know a bit more specific on how to do this, and whether this INVALID serial number will trigger SN error EVERYTIME the computer starts?

Thanks.

I bought a number of Lenovo ThinkCentre M93p Tiny for a WiFi project.

I noticed out of the 20 machines one will accept any WiFi card.

I upgraded the bios and controller firmware, and it's still booting up without the 1802 Unauthorized network card error.

Compared the SMBIOS between the different systems and they seem very similar.

Even the MAC address is in the same range.

Why is one machine allowing me to insert any card without error?

Hi all,

I have M93p tiny, but with different BIOS chip, i.e. the one in this tutorial using winbond, mine using MXIC.

I managed to dump the BIOS image, but what is weird is when I concatenate the two files with either way of concatenating, seems like no difference. 8MB+4MB and 4MB+8MB did not give different result when opening the resulting concatenated file in UEFI Tool.

And when I search respective card device ID, i.e. 8680b108 or e414b143, search result does not return anything.

When I open each of the BIOs dump file, only one file (the 8MB) that can be opened with UEFITool, while opening the 4MB resulting in error (I dont know if this normal or not).

I am not using the newest BIOS version yet here, by the way. Mine is the March2015 BIOS version.

Anything I might have done wrong here?

I Have used the universal Bios Backup.exe and Backup_Tools12.exe, hope this was correct way?

Please let ne know, if this not correct.

I know this may not be exactly what you all are looking for...
But I was able to circumvent the whitelist by adding the device I wanted to use to the existing whitelist - overwriting one of the other entries with the vendor/device ID I wanted.

Hello all. 
Just want to share, that the above thread and guide by tomado09 absolutely works. 
In the case of my M93p, here is what is the ingredients of success:
1. Use flashrom software to read, verify and afterwards write the BIOS. I am having a hard time using CH341a programmer, but very smooth when using flashrom. 
2. The placement of the SOIC clip is very crucial, to determine a successful read-verify phase. 
3. Don't forget to read and verify afterwards, to make sure that all the reads are identical. In my case, I do multiple read-verify on each chip, and then comparing (using HxD) between each read to make sure that all the subsequent reads are identical. 
4. The method and the tools for find and replace the whitelist also works. Just make sure you follow each process. 

Thank you.
