How can I remove the service tag off my bios? I tried using the dell support live image but I get this error: "ERROR: cannot change the service tag. Please ensure the tag is in a correct format, and the SETUP password is disabled." I ensured the tag was in the correct format and my setup password was indeed disabled. And if anybody knows anything about spoofing the serials off my type of motherboard (Insyde) please also let me know. Thanks.
