To add some more salt in the wounds of trying to bypass forced enrollment.... Over the past three days I have been learning, the hard way unfortunately, that people and sellers on the internet cannot be trusted at all. The guy I got this beautiful Dell CB13 from showed me it booted, fantastic! So I have found a possible solution but it does require purchasing some hardware and one of my old hobbies: Reprogramming EEProms. I do not want to violate any rules so here are two keywords to check online: SOP8 Flash Chip IC and CH341A USB programmer. The serial number needs to be changed and it is stored in a little EEProm on the motherboard. You are on your own from here.
