  <sect3 arch="arm"><title>Booting from TFTP on Netwinder</title>

<para>

Netwinders have two network interfaces: A 10Mbps NE2000-compatible
card (which is generally referred to as <filename>eth0</filename>) and
A 100Mbps Tulip card.

You need NeTTrom 2.2.1 or later to boot the
installation system. NeTTrom 2.3.3 is recommended: get these files
from
<ulink url="ftp://ftp.netwinder.org/pub/netwinder/firmware/"></ulink>:

When you boot your Netwinder you have to interrupt the boot process during the
countdown.  This allows you to set a number of firmware settings needed in
order to boot the installer.  You must first configure the network, either
with a static address:

<informalexample><screen>
    NeTTrom command-&gt; setenv eth0_ip 192.168.0.10/24
</screen></informalexample>

where 24 is the number of set bits in the netmask, or a dynamic address:

<informalexample><screen>
    NeTTrom command-&gt; boot diskless
</screen></informalexample>

You may also need to configure the <userinput>route1</userinput>
settings if the TFTP
server is not on the local subnet.  The rest of the config is pretty
standard (the save-all step is optional):

<informalexample><screen>
    NeTTrom command-&gt; setenv kerntftpserver 192.168.0.1
    NeTTrom command-&gt; setenv kerntftpfile boot.img
    NeTTrom command-&gt; save-all
    NeTTrom command-&gt; setenv netconfig_eth0 flash
    NeTTrom command-&gt; setenv kernconfig tftp
    NeTTrom command-&gt; setenv rootdev /dev/ram
    NeTTrom command-&gt; setenv cmdappend root=/dev/ram
</screen></informalexample>

Only the last four of these interfere with normal disk booting, so it is
safe to issue <command>save-all</command> right before them, which will
store the network settings in case you need to boot from the network
again.

If you want to use the serial console to install your Netwinder, you also
need the following setting:

<informalexample><screen>
    NeTTrom command-&gt; setenv cmdappend root=/dev/ram console=ttyS0,115200
</screen></informalexample>

Use the <command>printenv</command> command to review your
environment settings.
