&boot-installer-intro-net.xml; Netwinders have two network interfaces: A 10Mbps NE2000-compatible card (which is generally referred to as eth0) and a 100Mbps Tulip card. There may be problems loading the image via TFTP using the 100Mbps card so it is recommended that you use the 10Mbps interface (the one labeled with 10 Base-T). You need NeTTrom 2.2.1 or later to boot the installation system, and version 2.3.3 is recommended. Unfortunately, firmware files are currently not available for download because of license issues. If this situation changes, you may find new images at . 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: NeTTrom command-> load-defaults Furthermore, you must configure the network, either with a static address: NeTTrom command-> setenv netconfig_eth0 flash NeTTrom command-> setenv eth0_ip 192.168.0.10/24 where 24 is the number of set bits in the netmask, or a dynamic address: NeTTrom command-> setenv netconfig_eth0 dhcp You may also need to configure the route1 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. NeTTrom command-> setenv kerntftpserver 192.168.0.1 NeTTrom command-> setenv kerntftpfile boot.img NeTTrom command-> save-all Now you have to tell the firmware that the TFTP image should be booted: NeTTrom command-> setenv kernconfig tftp NeTTrom command-> setenv rootdev /dev/ram If you use a serial console to install your Netwinder, you need to add the following setting: NeTTrom command-> setenv cmdappend root=/dev/ram console=ttyS0,115200 Alternatively, for installations using a keyboard and monitor you have to set: NeTTrom command-> setenv cmdappend root=/dev/ram You can use the printenv command to review your environment settings. After you have verified that the settings are correct, you can load the image: NeTTrom command-> boot In case you run into any problems, a detailed HOWTO is available. On CATS machines, use boot de0: or similar at the Cyclone prompt. &boot-installer-intro-cd.xml; To boot a CD-ROM from the Cyclone console prompt, use the command boot cd0:cats.bin &boot-installer-intro-firmware.xml; There are three ways how to put the installer firmware into flash: Go to the administration section and choose the menu item Upgrade. You can then browse your disk for the installer image you have previously downloaded. Then press the Start Upgrade button, confirm, wait for a few minutes and confirm again. The system will then boot straight into the installer. You can use upslug2 from any Linux or Unix machine to upgrade the machine via the network. This software is packaged for Debian. First, you have to put your NSLU2 in upgrade mode: Disconnect any disks and/or devices from the USB ports. Power off the NSLU2 Press and hold the reset button (accessible through the small hole on the back just above the power input). Press and release the power button to power on the NSLU2. Wait for 10 seconds watching the ready/status LED. After 10 seconds it will change from amber to red. Immediately release the reset button. The NSLU2 ready/status LED will flash alternately red/green (there is a 1 second delay before the first green). The NSLU2 is now in upgrade mode. See the NSLU2-Linux pages if you have problems with this. Once your NSLU2 is in upgrade mode, you can flash the new image: sudo upslug2 -i di-nslu2.bin Note that the tool also shows the MAC address of your NSLU2, which may come in handy to configure your DHCP server. After the whole image has been written and verified, the system will automatically reboot. Make sure you connect your USB disk again now, otherwise the installer won't be able to find it. There is a tool for Windows to upgrade the firmware via the network.
