Intro

This tutorial explains how to create an usb-stick with the debian netinstaller on it. If you have a model containing the "Intel WiFi Link 5100" network card, then a standard Debian Lenny net install works fine and is entirely strightforward, however if you have the "Intel WiFi Link 5300" network card then the 2.6.26.x kernel used will not recognise it so you have to do extra work to do a netinstall.

USB stick

Partition and format the stick

Use

foo:~# fdisk -l

to look which device name your stick has. I will use /dev/sdb in this tutorial. Use fdisk oder cfdisk to create a partition of at least 200MB and format it in FAT16 like this:

foo:~# mkdosfs -F 16 /dev/sdb1

Don't forget to make the partition bootable. What looks like this if you use fdisk

foo:~# fdisk /dev/sdb

Command (m for help): a
Partition number (1-4): 1

Command (m for help): w
The partition table has been altered!


Install MBR

You need the syslinux packet to do this

foo:~# aptitude install syslinux

then

foo:~# dd if=/usr/lib/syslinux/mbr.bin of=/dev/sdb
404 bytes (404 B) copied, 0.0275888 s, 14.6 kB/s


Get and copy Files

You will need following files:
http://ftp.de.debian.org/debian/dists/unstable/main/installer-i386/current/images/hd-media/initrd.gz
http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/i386/iso-cd/debian-testing-i386-netinst.iso
as you can see i use the i368 architecture, download the appropriate files if you want to use an other architecture


and here is a self compiled vanilla 2.6.27.7 kernel:
http://www.congerro.net/pub/vmlinuz.bz2

unzip the vmlinuz.bz2-file:

foo:~# bunzip2 vmlinuz.bz2


If you don't trust me compile your own kernel ^^ Get the sources from kernel.org, untar them, cd into the kernel-source-directory and execute make, easy huh?


mount the usb stick

foo:~# mount /dev/sdb1 /mnt/usb

then create a directory named syslinux on it

foo:~# mkdir /mnt/usb/syslinux

copy all three files into the directory

foo:~# cp vmlinuz initrd.gz debian-testing-i386-netinst.iso /mnt/usb/syslinux

Now create a file named syslinux.cfg

foo:~# vim /mnt/usb/syslinux/syslinux.cfg

and paste following two lines into it

default vmlinuz
append initrd=initrd.gz ramdisk_size=12000 root=/dev/ram rw

unmount the usb-stick

foo:~# cd && umount /mnt/usb

and install the syslinux boot loader

foo:~# syslinux -d /syslinux /dev/sdb1

Finished \o/
Press F12 during boot to select the usb-stick as boot device.

Note

It is not possible to install the 2.6.27.x kernel with the debian installer but you can copy the kernel from the usb-device afterwards ^^
