Alternate 4.00 MB firmware dump carrying the 4330S model name and a copy suffix, suggesting a second sample of the same machine's BIOS. No board number, revision or version information is included, so compare it with the companion file before use. Such raw images are written to the SPI flash chip with an external programmer to repair corrupted firmware. Back up the original chip, keep any machine-specific data such as serial numbers, and make sure the chip capacity matches the 4 MB image.
