512-byte binary whose name only says i6400, most likely tied to the Dell Inspiron 6400, although the name does not confirm what chip it is for. The tiny size suggests EEPROM content such as panel EDID rather than a system BIOS, which would be far larger. Inspect it in a hex or EDID viewer to identify what it contains before use. If it is EDID, it is written to the LCD EEPROM with a programmer; always read and keep the original data first, as the wrong image can blank the display.
