Tiny 2-byte companion file holding the saved status register value from reading the flash chip that produced the 440 G4 COPY image. Some programmer software stores the chip status register this way, which covers write-protection and block-protect bits. It is not firmware and cannot be flashed by itself. It is useful when restoring the matching dump, so protection bits can be set back to their original state. Keep it alongside the 16 MB image and ignore it if your programmer software has no use for it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
