Hi, i have acer
SF315-41
i have removed the bios IC but it doesnt get detect by my programmer it say 6,7,8 pins are not connected or damaged . i tried 2 more programmers still no joy . can you extract the first version of bios as well as EC? i have soldered the 2.12 but it doesnt do anything . i have checked all powers comes on but doesnt display anything so it has to be bios issue. it use MX25U6435F bios name

i have created the isflash.bin is that correct?
