Ok, i have a HP Tablet PC TC1100, also known as a Tx1100. I have a need to change the serial number and the asset tag. I've tried using DMI tools however they can not write to this Bios. There is a field for the serial number (and other fields for much more information) in many generic BIOSes and methods to read these fields. The person manufacturing the BIOS should fill this with the correct information. Unless that is done the fields often read their default values (e.g. 'insert manufacturers name here' rather than the proper name.
I have two Panasonic toughbook CF-31 with AMI BIOS. One with locked BIOS, another on is OK. I used afudos to dump rom file from that unlocked one, and flashed bios on that locked one with that rom file. There was an error-wrong rom id, bu I used switch /x to ignore it. After flashing BIOS is unlocked, everything works, but serial number in BIOS is incorrect. BIOS shows serial number from laptop that was without BIOS password. I tried many programs to change serial, but non of them does work.
I read that DMIEDIT should work but I cant find link for download.
Does anyone have that program or some other idea?

There aren’t any supported non-WMI techniques to change a Hyper-V virtual machine’s BIOSGUID/UUID. Up through 2012 R2, you can modify the.XML file directly. From what I’ve seen of the new virtual machine file format in 2016, you should be able to perform something similar using a binary file editor.
