User-specific boot menus

This page outlines the steps I took to implement a proof of concept comprising user authentication at preboot time and dynamically generated boot menus. The user is first presented with a login screen. The user's credentials are passed via an SSL-encrypted link to a server, which authenticates the user and then provides a boot menu containing a list of authorised boot selections. The list of boot selections can vary according to the user.


Find a suitable Apache web server, complete with valid SSL certificate. Create a directory called “boot” on this web server. For the purpose of this documentation, I will assume that the full URI for this directory is http://my.web.server/boot.

In the boot directory, create a file “.htaccess” containing


and a file “menu.gpxe” containing

  kernel -n menu https://${username:uristring}:${password:uristring}@my.web.server/boot/vesamenu.c32 menu.php
