<sect3 arch="arm"><title>Booting from TFTP on NetWinder</title>
<para>
NetWinders have two network interfaces: The 10Mbps NE2000-compatible
card is <filename>eth0</filename> and the 100Mbps Tulip card is
<filename>eth1</filename>.
</para><note><para>
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>:

After rebooting and interrupting the boot process during the countdown, you
must first configure the network either with a static address:
<informalexample><screen>
NeTTrom command-> 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-> boot diskless
</screen></informalexample>
</para><para>
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-> setenv kerntftpserver 192.168.0.1
NeTTrom command-> setenv kerntftpfile tftpboot.img
NeTTrom command-> save-all
NeTTrom command-> setenv netconfig_eth0 flash
NeTTrom command-> setenv kernconfig tftp
</screen></informalexample>
</para><para>
Only the last two of these interfere with normal disk booting, so it is
safe to <command>save-all</command> right before it, which will
store the network settings in case you need to boot from the network
again. Use the <command>printenv</command> command to review your
environment settings. Finally, if your <envar>cmdappend</envar>
NeTTrom variable has the <option>noinitrd</option> option (which is
necessary to boot 2.4 kernels), you must remove it so the downloaded
kernel can boot with its attached ramdisk.
