I already did the "restore stock" procedure.

What it did, AFAIK, was force the box to fetch some bits via TFTP.
Then, those fetched bits grabbed some more to reinstall the box properly.

If I can have the box fetch "bootmini2440", will it automatically try to find 
some NetBSD kernel or will it drop to prompt and wait until I issue "dhcp" and 
"go" commands ; as seen here (http://xpg.dk/nb-mini2440-ht/) ? That way I could 
prepare a remote NFS install.

Sorry, I thought it was better to shortened them.

Thanks.
