Post the laptop serial number.. .What model is your programmer and software version. What part number is etched on top of the bios chip, is it in the programmers support list, is it detected. Is it 3.3V or 1.8V

The 25Q80EWS chip is 8-Mbit , 8 Mega bits. 8-Mbits is equal to 1MB Mega Byte. It is not the bios chip, it will be the firmware for the vBios, Thunderbolt or something else. Read this thread - https://www.badcaps.net/forum/troubl...fh52m-la-j891p
