How to change the Service Tag in a Dell Latitude D630 BIOS

I have a Dell Latitude D630 and the motherboard died, It's out of warrenty so I bought a Motherboard on ebay. The Bios Service Tag does not match the number on the bottom so I would like to chage it to the correct one. How can I do this?

I read about a DST CD = Dell Service Technician CD that has this option but I can't find one.

It's not a real important thing but when I use the Dell System ID application it reads the Bios Service tag and not the real system tag that Is registered to me.

If your Dell motherboard has an asset tag Dell says it cannot be changed. Only if the motherboard asset tag area is blank can you add a new tag
