How to identify lenovo B450 bios chip

[benmintaarhin]

Greetings,
I have to reset a forgotten bios password by flashing the eeprom chip. The laptop is lenovo B450, it has been very difficult for me to identify the eeprom chip and i would be more than happy if you can help me identify it on my motherboard.
