Sorry! You have to remove the IC Bios from the motherboard and program it using a programmer.
If you haven't done it yet, you may damage the motherboard.

Good morning,

I don't understand, when I dump the bios of a latitude 7400 and save it, it only weighs 1025KB. This is the WINBOND IC 25Q80DVSIG. I wonder if I have the wrong integrated circuit... Merry Christmas

I finally found the bios chip. This is the 25B256DV which is located on the other side of the motherboard. I unlocked your bios, it worked fine

Hello,
It is possible to change service tag ?

If I use someone else's bios, I will have the same service tag. Does this pose a problem? Will I have problems with DELL service if I use SupportAssist to download the drivers?
