Hi all,

I'm on 4 forums and have asked the same question with zero response so far, hoping @CodeRush might be able to shed some light on this.

I am willing to try ANYTHING at this point to make the necessary modification to my PC. I had an old PC motherboard fry itself after a storm and was able to get an old working Dell OptiPlex 9010 motherboard for free from an eWaste Recycling Centre. I just want to remove the main identifier now that it is no longer under warranty etc which is the Service Tag.

I have tried the following:
*Flash BIOS to latest version A26 with silent switch '-wipeall':
https://downloads.dell.com/FOLDER04326356M/1/O9010A26.exe
(http://mickitblog.blogspot.com.au/2011/0...s-switches.html)
*Dell.BIOS.Reset.iso with asset.com/asset209.com using silent switches
*Dell Command Configure command prompt using cctk.exe --svctag
*DMIEdit

Issues with those tools:
*asset.com & asset209.com appear to not support newer OptiPlex builds (OptiPlex 9010 circa 2013).
*cct.exe --svctag returned a 'read-only' error when trying to mod the file.
*The silent switch '-wipeall' & '-wipeclean' were not recognised with the new Dell BIOS exe updates.
The '-wipeall' switch seems to indicate that it would do what I need "Cleans the DMI Data Area, Password, Service Tag, and Asset Tag". It seems to put the BIOS back to a blank factory type state.
*DMIEdit throws "can't update smbios data with pnp function on current system"

I have even tried to use an AMI tool to try and reflash the BIOS but I get a 'BIOS write-protected' error.

Surely someone, somewhere can find a way to wipe 6 digits?

Is the Service Tag stored in the BIOS? Or is it in SLIC? If it is in the BIOS there must be a way to flash it and blank the field? In CrystalDMI.exe I am able to see the ServiceTag and asset data.
I also found this but I'm not sure what it is or how to use it: https://github.com/dell/libsmbios

Can't you just swap the bios chips on those motherboards- if those are in sockets?
Well... NVRAM with this Tag could be on another chip but it's worth a try.

service tag is an editable field INSIDE the BIOS.
just enter the BIOS and delete/edit it.

I managed to remove several service tags on Optiplexes, from 755 up to 960 and 790, inside Bios did you remove all security and passwords before any attempt?

I don't understand what is the issue here.
Service tag doesn't affect platform's function in any way, it doesn't prevent anything from working as expected, why touching it?

Got it. Can you provide the dump and the value of service tag so we can search for it there?

Hope this is what you mean by dump? https://www.sendspace.com/file/3pard9

I'll PM you the ST

Just an update I'm still working on this, think a solution has been discovered and will provide a full write-up once it's worked out.

Did anyone figure out how to change the service tag?

What was the solution please?

What is the solution???
