1. This procedures are used to update the flash / DOM (disk on module) firmware on the NAS.
2. Make sure no HDD installed before update.
3. Flash image are required for NAS with 16MB flash or 128MB DOM.
4. For NAS with 512MB DOM, just use the firmware on QNAP download site (http://www.qnap.com/download.asp).
5. This updated procedures are generally used when the NAS can be found by QNAP Finder but cannot be initialized with HDD(s).
6. QNAP NAS also store firmware on the HDDs. If you have initialized the NAS with HDDs before, this update procedures will cause the firmware version mismatch between the NAS and the HDDs. You need to update the firmware again after boot up with HDDs installed.
