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. text/html 2009-11-05T15:46:25-07:00 http://etherboot.org/wiki/appnotes/autobootchainurl?rev=1257464785&do=diff Autoboot without a DHCP-supplied boot path gPXE can be built with an embedded image, which might be a script.
