Firmware for the IQ2X0IH board at version 1.1, stored in an 8.74 MB ZIP archive. The name gives no brand or device model, so identification depends on matching the IQ2X0IH code silkscreened on the motherboard. Extract the archive and check the binary size against the flash chip before programming; a separate 16 MB dump with the same code also exists, suggesting the target chip may be 128 Mbit. Write the image with an SPI programmer only after reading and storing the original contents, which may contain serial or MAC data.
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 @biosarchive. Enginerys does not host this file.
How to open a .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
