Firmware for the LG 22V280 all-in-one, with EAX67843201, an LG board part number, also in the name. The archive is very small at 49.7 KB, so it probably holds a small EEPROM dump or a similar compact image rather than a full BIOS, but the name does not say which. Technicians write such data with a programmer to fix display, boot or settings faults. Check what is inside, identify the target chip on the board, and back up its original contents before writing.
