Small 136 KB ZIP containing firmware for a device identified only as E1940S-PN. The name states no brand, so the exact product is not confirmed here; the code resembles a monitor model, and a file this size often holds a display scaler or EEPROM dump rather than a laptop BIOS. Verify the model sticker and the chip type on the board before writing anything. Read the existing chip with your programmer and keep the backup, and check the image size equals the chip capacity before flashing.
