Firmware package for the Zyxel DR-810 network device, 1.50 MB in RAR form. The name gives no version, hardware revision or flash chip, so the contents need checking after extraction to see whether it is a raw flash dump or a vendor update image. Raw dumps are written to the SPI flash with a programmer to recover a device that no longer boots, while update images go through the web interface or recovery mode. Back up the existing flash first and compare image and chip sizes.
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.
