&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. You need NeTTrom 2.2.1 or later to boot the installation system. NeTTrom 2.3.3 is recommended: get these files from : nettrom-2.3-3.armv4l.rpm nettrom-2.3.3.bin nettrom-2.3.3.bin.md5sum 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: 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-> boot diskless You may also need to configure the route1 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): NeTTrom command-> setenv kerntftpserver 192.168.0.1 NeTTrom command-> setenv kerntftpfile boot.img NeTTrom command-> save-all NeTTrom command-> setenv kernconfig tftp NeTTrom command-> setenv rootdev /dev/ram NeTTrom command-> setenv cmdappend root=/dev/ram Only the last three of these interfere with normal disk booting, so it is safe to issue save-all 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: NeTTrom command-> setenv cmdappend root=/dev/ram console=ttyS0,115200 Use the printenv command to review your environment settings. 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
