Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and https://flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Error accessing GD25Q256D, 0x2000000 bytes at 0x00000000fe000000 /dev/mem mmap failed: Operation not permitted Could not map flash chip GD25Q256D at 0x00000000fe000000.
