Each distinct ARM architecture requires its own kernel. Because of this the standard &debian; distribution only supports installation on a number of the most common platforms. The &debian; userland however may be used by any ARM CPU. Most ARM CPUs may be run in either endian mode (big or little). However, the majority of current system implementation uses little-endian mode. &debian; currently only supports little-endian ARM systems. The supported platforms are: IOP32x Intel's I/O Processor (IOP) line is found in a number of products related to data storage and processing. &debian; currently supports the IOP32x platform, featuring the IOP 80219 and 32x chips commonly found in Network Attached Storage (NAS) devices. &debian; explicitly supports two such devices: the GLAN Tank from IO-Data and the Thecus N2100. Kirkwood Kirkwood is a system on a chip (SoC) from Marvell that integrates an ARM CPU, Ethernet, SATA, USB, and other functionality in one chip. We currently support the following Kirkwood based devices: OpenRD (OpenRD-Base, OpenRD-Client and OpenRD-Ultimate), plug computers (SheevaPlug, GuruPlug and DreamPlug), QNAP Turbo Station (all TS-11x, TS-21x and TS-41x models), and LaCie NASes (Network Space v2, Network Space Max v2, Internet Space v2, d2 Network v2, 2Big Network v2 and 5Big Network v2). Orion5x Orion is a system on a chip (SoC) from Marvell that integrates an ARM CPU, Ethernet, SATA, USB, and other functionality in one chip. There are many Network Attached Storage (NAS) devices on the market that are based on an Orion chip. We currently support the following Orion based devices: Buffalo Kurobox, D-Link DNS-323 and HP mv2120. Versatile The Versatile platform is emulated by QEMU and is therefore a nice way to test and run &debian; on ARM if you don't have the hardware.
