Netbooting

The Open Desktop Workstations (ODWs) use SmartFirmware. The SmartFirmware user manual has a good netbooting tutorial. The DHCP support in the firmware is slightly buggy and requires inserting a client and server IP of 0.0.0.0 in the boot-device string, like so:

setenv boot-device eth:dhcp,0.0.0.0,,0.0.0.0

(The double comma indicates an empty boot file name--it is supplised by the DHCP server.)

This can be saved in the firmware by editing the nvramrc script. To begin editing, type nvedit and add the above command to the end of the list (change 'eth' to the devalias of whatever ethernet device you wish to use). When finished, hit control-C to exit the editor. Then, type nvstore to save your changes.
