can't find command 'fwsetup'.

Hi,

I just got untangle installed on this box:

http://www.amazon.com/Intel-celeron-..._detailpages00

On initial boot, if I go to system setup I receive "error: can't find command 'fwsetup'.

I assume I want to go through system setup before anything else? What is this command and could I load it manually from the install iso?
