Change Motherboard Serial Number Using

Re-entering the server serial number and product ID

Another thing to note is the serial# is stored in the BIOS and often on a programmable EEPROM chip. If u ever had a bad flash, remanufactured board, ran a program to update flash values to user specified values, or simply never had the serial# programmed for any reason you can get empty string for that machine. After being on the phone with Dell (and trying to use the asset application to change the service tag) I was told that the motherboard had to be replaced and the tech would put on the correct service tag. This didn't seem right to me as the system was working perfectly otherwise, so I did some digging on the net. Here is my solution.
