Sure, but there is no instruction for the use of proper commands with that tool just:
nvram: (usage: no such option as -?)
nvram [-x] [-p] [-f filename] [-d name] name[=value] ...
-x use XML format for printing or reading variables
(must appear before -p or -f)
-p print all firmware variables
-f set firmware variables from a text file
-d delete the named variable
-c delete all variables
name=value set named variable
name print variable
Note that arguments and options are executed in order.
What would be the proper format for the 'file'?
If your Netboot server resides on a different subnet than your client machines, you will have to configure your network router to pass the necessary BSDP traffic between subnets. If you don't have control of the router config, talk to your Network admin. If the router is Cisco kit, the 'ip helper-address' command will be what's needed to make this work. Failing that, do the following:
On PPC machines you need to issue the following command in Terminal.app:
sudo nvram default-bootp-vexts="%00"
Then you can issue this command:
sudo nvram boot-device enet:220.127.116.11
where '18.104.22.168' is the IP address of your Netboot server. These values will stay in nvram until they are reset.
