    Ok so with a bit of help I've managed to backup my BIOS using "BACKUP_Tools19l" which appears to make a dump of my BIOS to a .bin file.
    I've been able to open it up in a HEX editor and make the required modifications, only trouble is machine is a Dell write-protected Dual-chip BIOS.

    I have my .bin/.rom fil;e but have no idea on how to flash the modded dump back? Any ideas?

    @Carlos Detweiller Do you know were I can go, or, how can I do to change Dell Service Tag?

    Nope, I'm not a BIOS/UEFI guy, sorry.
