Now that 8CB based workstations start pouring in,
let's prepare the configuration for 1E8CB mobos
(3 PCIe slots so 1/2/3-seaters possible and tested).

This should have been done when reworking Workstation,
but better that late than making a copy for Education.

NB: directory name has been chosen to both sort late
    (so that functionality related checkboxes come first
    and graphics setup related ones sit down there), and
    to relate to X11 as well.
