This is a basic setup to boot Arch Linux over PXE.

1. Mount the Arch Linux image.

    mkdir -p /mnt/archiso
    mount -o loop,ro archlinux-2013.02.01-dual.iso /mnt/archiso
   

2. Connect your server with your client and setup the server interface for that connection with a static ip address in the /etc/network/interfaces file.

    auto eth0
    iface eth0 inet static
    address 192.168.1.100
    netmask 255.255.255.0
    gateway 192.168.1.1
   

   Restart the network interface.

    ifdown eth0
    ifup eth0
   

3. Configure dnsmasq as dhcp- and tftp-server in /etc/dnsmasq.conf.

    dhcp-boot=/mnt/archiso/arch/boot/syslinux/pxelinux.0
    dhcp-option-force=209,boot/syslinux/archiso.cfg
    dhcp-option-force=210,/mnt/archiso/arch/
    enable-tftp
    tftp-root=/mnt/archiso
   

   Restart the service.

    service dnsmasq restart
   

4. Start an http-server inside the Arch Linux mount folder.

    python -m SimpleHTTPServer 80
