Frequently Asked Questions (FAQ)
Is Debian on the QNAP TS-409 fully supported?
Debian includes support for the QNAP TS-409 but the device is no longer supported by Debian installer. The recommended way to install Debian is to install Debian 6.0 (squeeze) and then perform an upgrade to Debian 7 (wheezy) and then to Debian 8 (jessie).
Is Debian on the TS-409 suited for people new to Linux?
No, I would not recommend you install Debian on your QNAP if you don't have any experience with Linux and Debian. Debian will not install a web interface through which you can control your QNAP, so I recommend you stay with the QNAP firmware.
Can I have both the QNAP firmware and Debian?
No, Debian will completely replace the QNAP firmware on disk and in flash. You have to choose between the QNAP firmware and the Debian installation described on my pages. However, it would be possible to make a small Debian system on your disk with the QNAP firmware by using
Can I go back to the QNAP firmware if I don't like Debian?
Yes, you can restore the original QNAP software without any problems.
Will this installer work on the QNAP TS-409U?
Yes, the TS-409U is fully supported.
Will this installer work on the QNAP TS-101 or TS-201?
Will this installer work on the QNAP TS-509?
No, the QNAP TS-509 is based on an Intel Celeron chip and therefore not compatible with this installation routine which only supports QNAP devices based on Marvell's Orion (ARM) chip.
Is there a recovery mode?
Yes, the TS-409 has a recovery mode with which a firmware image can be written to flash. This is useful in case there are problems during the installation or an upgrade of Debian. See the recovery mode page for more information.
Is the serial header soldered onto the board already?
Yes, a serial header is on the main board. You only need to prepare a cable with a TTL level shifter for a serial console.
Will I need a serial console to use Debian?
No, the installation and operation of Debian on your QNAP doesn't require a serial console.
