Firmware archive of 1.60 MB for the P-793H, a model name in the Zyxel Prestige series of DSL routers. No version or release date is given, so the archive should be opened and the firmware checked before use. Such images are used to bring back units with a failed upgrade or corrupted firmware, usually through the bootloader recovery console over serial or Ethernet. Verify the hardware revision on the unit label, since Prestige models were made in several versions with incompatible firmware, and keep a backup.
