The web server software you use on your WAN boot server and install server must meet the following requirements.
Operating system requirements – WAN boot provides a Common Gateway Interface (CGI) program (wanboot-cgi) that converts data and files into a specific format that the client machine expects. To perform a WAN boot installation with these scripts, the web server software must run on the Solaris 9 12/03 OS, or compatible version.
File size limitations – Your web server software might limit the size of the files you can transmit over HTTP. Check your web server documentation to make sure the software can transmit files that are the size of a Solaris Flash archive.
