to change Bios version

with rom, I have olny succeded to change Motherboard serial number.

Till now I can change MAC, serial of primary partition, name/type of HDD, maybe HDD serial number but no idea how to make it make nothing, user name, computer name and Bios version.
If I want to keep Bios id on other PC, then have to choose I moved it.

any sugestions for Bios and CPU names and serial numbers are welcomed.
