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. First of all, start by loading the default settings: <informalexample><screen>
NeTTrom command-> load-defaults
</screen></informalexample> Furthermore, you must configure the network, either with a static address: <informalexample><screen>
NeTTrom command-> setenv netconfig_eth0 flash
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-> setenv netconfig_eth0 dhcp
</screen></informalexample> You may also need to configure the <userinput>route1</userinput> settings if the TFTP server is not on the local subnet. Following these settings, you have to specify the TFTP server and the location of the image. You can then store your settings to flash. <informalexample><screen>
NeTTrom command-> setenv kerntftpserver 192.168.0.1
NeTTrom command-> setenv kerntftpfile boot.img
NeTTrom command-> save-all
</screen></informalexample> Now you have to tell the firmware that the TFTP image should be booted: <informalexample><screen>
NeTTrom command-> setenv kernconfig tftp
NeTTrom command-> setenv rootdev /dev/ram
</screen></informalexample> If you use a serial console to install your Netwinder, you need to add the following setting: <informalexample><screen>
NeTTrom command-> setenv cmdappend root=/dev/ram console=ttyS0,115200
</screen></informalexample> Alternatively, for installations using a keyboard and monitor you have to set: <informalexample><screen>
NeTTrom command-> setenv cmdappend root=/dev/ram
</screen></informalexample> You can use the <command>printenv</command> command to review your environment settings. After you have verified that the settings are correct, you can load the image: <informalexample><screen>
NeTTrom command-> boot
</screen></informalexample> In case you run into any problems, a <ulink url="http://www.netwinder.org/howto/Firmware-HOWTO.html">detailed HOWTO</ulink> is available.
