Hello folks, my Zephyrus has a bricked bios and I am trying to recover it. So far I took it apart and found out that there are 2 Winbond chips on the motherboard.
One could be EC bios and the other one the main bios so I need some help identifying the right one before I read and dump from the chip.
1st one is located next to the RAM and is Winbond 25Q80EWING 1805 (1.8V 8M-BIT)
2nd one is near the SSD and display connector - Winbond 25Q80DVSIG 1803 (3V 8M-BIT)
If I read both I am not sure how to identify the one that holds the actual bios. I am not certain how to proceed as of now so any help will be greatly appreciated.
Edit: I also located another chip candidate: 25B127DSIG, note that 25Q80EWING looks slightly smaller than the other two chips.
Hi. did you manage to identify wich on is wich?
