hello everyone , I need your help,
I have a pc, xps 8940 does not work with cpu gen11 only with gen10.
I tried to update the bios but nothing changed.
I found bios bin on the internet which I programmed.
it works with it, but every time it starts,
the TPM not found error appears and the service tag is not saved in the bios.
after restart service tag window remaing clear. i attach original bios dump.
thank you. here some pics....

Re: Dell xps 8940 bios

is possible to insert a service tag direct into bios?

Re: Dell xps 8940 bios

In left corner apear this error BAC6D992
otherwise nothing has changed, service tag remain empty. and (manufacturing mode active) still apears on every start. It bypasses these errors but it is annoying for the buyer.
maybe SIO is programmable?MEC1515-Z2 and not write over the old content? I do not know

Re: Dell xps 8940 bios


Yes, you need to re-flash the BIOS.



Your steps is fine....
