Take hi-res photo of your whole mainboard and attach here. We need to inspect every 8-pin chip (lables as well), so you can do more photos by pieces. We don`t have your m/b and eeprom location. Look at this wiki article. You have to search for 8-pin chip, labeled ATML.. or just digits (eg. 24512) near to the SoC.

You just could post labels of 8 pin chips next to the photos in this post.

I have updated my posting and sharing of the pics and now it should be possible to read the
chips..

I see Z1021HAI | ZA0E37
Z1031AI | ZA0H38

on the backside of the board I found a chip IC8002 with was labeled ATLMH016 and nearby i found a description TP_FRCS_EEPROM_WP
and a second one IC 8505 beginning with (maybe) 4256BRP (it's not good to read) and here a description like TP-LD-EEPROM_WP

Question: Are there "two eeprom chips" on the board ?
1. for Firmware / Operating System IC8002 found here https://www.dropbox.com/sh/hwqfncfymlut ... C00183.JPG
2. for Settings / Configuration IC8505 found here https://www.dropbox.com/sh/hwqfncfymlut ... C00191.JPG
