The code for the bootrom for selected cards (ed0 driver, basically) is alredy available on FreeBSD. Probably it would be nice if the if_xxx drivers were a bit easier to integrate with the "netboot" code. > What net boot servers can be got for FreeBSD ?

The only concern might be with the absence of keyboard and video board. Perhaps it is just a matter of disabling probes to these devices.
