Dave,
The client is just a p3 800 mhz, equipped only with a matrox g450 with tv out cable and a via rhine network card fitted with a boot prom. The software resides entirely on the server, which runs the dhcp and tftp servers required for netbooting.
would you mind providing some more information about your netboot image? Maybe even make the image/ tools available for other people to use?
I currently have a single VDR installation, but want to create a recording only server in my attic, plus use the other machine as my live view system plus VOMP server. Saving a harddisk would be nice... ;-)
