This error indicates that you have attempted to retrieve a non-existent [[:settings|setting]].
Things to try:
* If you are using the ''[[:cmd:show]]'' command in an iPXE [[:scripting|script]] to display the value of a setting, consider using the ''[[:cmd:echo]]'' command instead. For example: #!ipxe
dhcp
echo IP address: ${net0/ip}
You may also want to use the ''[[:cmd:isset]]'' command. For example: #!ipxe
dhcp
isset ${net0/ip} && echo IP address: ${net0/ip} || echo No IP address
