Firmware archive for a Zoltrix ZW888, marked test OK in the name, meaning the image was reported working. The name gives no board revision, flash chip or capacity, so inspect the 1.89 MB RAR contents before use. Such files are typically written to the device flash with a hardware programmer to recover from corrupted firmware. Read and save the original chip first, compare the image size with the chip capacity, and check the device model markings match.
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.
