Thinkstation C30 Machine Type and Model (MTM) after Motherboard upgrade.

2021-07-21, 9:47 AM

Hello!
Some time ago I have replaced the motherboard of my old C30 1097 Thinkstation
by the new 03T6737 MB supporting Ivy Bridge (v2) E5 Xeon.

Now, the machine turns to 1137 model, however it beeps on start due to SN and MTM absence.

 

According to the document:
How to update the Machine Type and Model (MTM), System Serial Number (SN), or System Brand ID of system BIOS menu – ThinkCentre, ThinkStation
https://support.lenovo.com/pe/en/solutions/ht501039
I should use amidedos.exe to set MTM.

Would you please advice which MTM should I set?
109719G or 1137???

If I understand correctly, the document advices to set the old MTM, 
but the Lenovo System Update utility 
uses this info for BIOS updates.
 
The 1097/1137 BIOS mismatch will  brick the system.

Hello,

 

Your original MTM/SN should be on a black and white tag somewhere on your system chassis. There should actually be two locations with the MTM/SN identified. On the front with a small sticker with just the MTM/SN and then a much larger Lenovo manufacturing sticker with a significant amount of info on it. If you are missing both of those there should also be a long black and white sticker with a number and barcode on the back and built into that is your MTM/SN.

Hello Croooowe,
>Your original MTM/SN should be on a black and white tag somewhere on your system chassis. 
Thank you for the reply.
I do know the original MTM/SN
However, after installation of the spare Lenovo 03T6737 motherboard,
the 1097 model has been transformed into 1137 model with the completely different BIOS.

If only I set the old MTM, the Lenovo System Update utility 
uses this info for BIOS updates
and ... 
I don't know what happens.

Apologies, I did not catch you had the original. 

 

What BIOS version currently shows in your BIOS menu? If you screen shot the BIOS please remove or blur your SN from the image.

Also, bear in mind that an incorrect BIOS will only install and potentially harm a system if you force it. Each BIOS update is designed to recognize if the update is correct for the system it is run on. It will halt the update in a number of ways, sometimes prompting the user of the mismatch and sometimes it just cancels the process without any notification.

Hello Croooowe,

Thanks very much for quick response.

> What BIOS version currently shows in your BIOS menu? 

I have attached the CPU-Z info about my current configuration.

> ... an incorrect BIOS will only install and potentially harm a system if you force it. 

I have found several discussions of similar problems. For example:

https://forums.lenovo.com/t5/ThinkStation-Workstations/Thinkstation-C30-BIOS-update-failed-system-will-no-longer-boot-BIOS-recovery-failed/m-p/5065015?page=1#5252747

This is why I asked the question.

Your current board is running "A3" BIOS, which is the version required to support IVB (v2) CPUs.  The board should only allow other versions of A3 BIOS to be flashed to it.  Attempting to run A1 BIOS (the version used on older v1-only capable boards would fail due to a BIOS ID mismatch.  The MTM really doesn't play into the flash process at a low level.

 

Where you might see the MTM come into play is in trying to use some software platforms like Vantage as it's possible they might key off the MTM.  But the flash utilities that software is using (which is essentially the BIOS flash from OS package) has other checks built in to ensure that the wrong BIOS level cannot be flashed on an existing system.  So in your case, it would only allow A3 BIOS to be flashed, and not A1.

 

From the sounds of it, your original problem is that with the new board, it's flagging an error with an invalid MTM/SN.  You should be able to correct that by re-flashing BIOS and looking for the prompts (prior to the flash) to change the machine type and serial number.  There are other tools in the BIOS flash package you can use to update these specific fields without running a full BIOS flash as well, but these typically take some command line knowledge to use.  So running the BIOS flash update and looking for the prompts is easier for most people.
