-===== How to install debian squeeze ==== +
- +
-==== Quick install ==== +
- +
-  * Format a usb key in dos format. One partition. +
- +
-  * Download [[ftp://lacie-nas.org/kernel/kirkwood/debian-installer-kirkwood/uImage-2.6.35-debian-installer|Image-2.6.35-debian-installer]], and rename as uImage on the usb key. +
-  * Download clunc at .... +
-  * Create a shell script with +
-<code bash> +
-#!/bin/bash +
- +
-#  +
-nas_ip=192.168.1.9 +

-  * Check that your nas is connected with Ethernet cable and can have access to internet using DHCP. +
-  * Then run the script, you will see this message: +

-==== Details install ===== +

-=== Patch the initrd === +
- +
-We patch the debian installer initrd to include a 'presseed' file. This file will contains automatic answer when the debian installer will ask to configure the network. Another solution is to put all answers on the kernel command line. I use this script to unpack the initrd and rebuild it +
- +
-<code shell> +
-#!/bin/sh +
- +
-wget http://ftp.fr.debian.org/debian/dists/squeeze/main/installer-armel/current/images/kirkwood/network-console/qnap/ts-219/initrd.gz +
- +
-rm -rf unpack +
-mkdir unpack +
-cd unpack +
-zcat ../initrd.gz | cpio -imd --quiet +
-rm -rf lib/modules/2.6.32-5-kirkwood +

-=== Rebuild your own kernel === +
-  +
-Debian squeeze kernel (2.6.32) is too old for your board. You must use a recent kernel (>=2.6.35). +
-Download this [[ftp://lacie-nas.org/kernel/kirkwood/debian-installer-kirkwood/uImage-arm-kirkwood-2.6.35|prebuilt kernel]] to boot debian-installer. +
- +
-Include the ../debian-installer.cpio into the kernel.  +
- +
-Note: uImage must not be greater than 6Mbytes. (U-boot will not support it). +
- +
-TODO +
- +
-=== Boot debian installer with clunc === +
- +
-==== TROUBLESHOOTING ==== +
- +
-If you get "failed to download a file" error during the install, try the following clunc script with "debian-installer/allow_unauthenticated=true": +
- +
-<code bash> +
-#!/bin/bash +
- +
-#  +
-nas_ip=192.168.1.9 +
-# You can get it by ifconfig eth0 +

-usb reset; +
-fatload usb 0:1 0x800000 uImage; +
-usb stop; +
-bootm 0x800000; +
