Different switches use different terms as well, you might see portfast (Cisco), client (Dell), other (Other) so read your documentation for your switch to determine how to properly set up Spanning Tree.  We've been forced to set our CISCO switches to portfast for PXE to work, but our HPs don't have this issue.
