Xerox WorkCentre 7220/7225 billing data stored where?

[Detonation]

Ethernet port broke on a near new 7220, so I replaced the SBC PWB with one form a know working machine. I made sure I transfered the original EEPROM as well as flash card, and performed Altboot. However, the near new machine now shows billing data of the old machine. Vice versa, when I boot the old machine, it shows the billing data of the new machine.

I didn't switch over the memory module, but as this is simple RAM I cannot believe billing data can be stored there. What am I missing? The serial number data are correct, so it's just the billing data that are transfered.

I would try to swap back the hdd and sd, altboot then the machine should have original meters.

The meters are located in the SD card. NOT the HDD
