You can use 16-bit add checksum of original eeprom dumps for idenifing HW/SW numbers
Here are some cases:
0261200280 037906022B 1267356092 CS=91D1
0261200280 037906022B 1267356189 CS=93EE
0261200342 037906022CN 1267356348 CS=21D8
0261200342 037906022DM 1267356636 CS=5EDF
0261200346 037906022CP 1267356046 CS=87F2
0261200552 037906022EH 1267357296 CS=73B3
0261200346 1267356409 CS=91F2
thank you, but when I have some moded files? There is another checksum
