Firmware image named K17C121C, a 128 KB .ROM file. The name gives no brand, model or board number, so its target device is not clear from the label alone. The size suggests a small 1 Mbit flash, of the kind often used for an embedded controller or an older system BIOS. Inspect the header in a hex editor for vendor or version strings before use, confirm the chip capacity matches, and keep a full backup of the existing chip before any write.
