Debian on the Thecus N2100
The Thecus N2100 is a Network Attached Storage (NAS) device based on Intel's IOP 80219 CPU and it can be used to run Debian. It offers the following features:
- Intel IOP 80219 CPU running at 600 MHz
- 2 SATA slots
- 1 DDR400 slot, populated with 128 MB RAM
- 3 USB 2.0 ports
- 2 GBit Ethernet
- 1 mini-PCI slot
These specs are similar to comparable NAS devices but one special feature of the N2100 is that it features a normal, expandable DDR400 RAM slot. In theory, up to 1 GB are supported using 64-bit DDR RAM, but RedBoot needs major modifications to support more than 512 MB.
While this device is produced by Thecus and sold as the Thecus YES Box N2100, it is also available from a number of other companies. The only difference is that some of those vendors include 256 MB rather than 128 MB RAM. So far, the following devices based on the Thecus N2100 are known:

Thecus for providing an N2100 to Lennert Buytenhek and me, for answering some questions in great detail and for generally supporting this effort. Lennert Buytenhek integrated support for the Thecus N2100 into the mainline kernel and significantly improved generic IOP support. David Karlström and Riku Voipio reverse-engineered various aspects of this machine, and Riku also wrote a driver for the fan and LEDs.
