Original data for a Lenovo G580 laptop, 256 bytes in size. Despite the BIOS label, a file this small matches the size of a display EDID block rather than a system firmware image, so it most likely comes from the LCD panel EEPROM; the name does not state the panel model. Such a dump is used to restore panel identification when the screen stays dark or shows the wrong resolution. Compare the panel installed in the machine with the source before writing, and save the current EEPROM contents first.
