Linksys NSLU2 installer images for Debian
The Linksys NSLU2 is no longer supported by Debian.

The Intel IXP4xx chip used in the Linksys NSLU2 needs some proprietary microcode for the Ethernet driver. As such, it cannot be distributed by the Debian project since we believe in free software and the advantages it offers to our users. While you can download an NSLU2 image directly from Debian this is probably not what you are looking for. It will only work if you use a USB Ethernet adapter. If you wish to use the Ethernet port of your NSLU2, you have to use the unofficial images which are a copy of the Debian images plus the proprietary Ethernet microcode.
Once you have obtained the installer image, please follow the installation guide.
