<just typing a B to the prompt would do it, or B <bootstrap device> such <as <B CSA0 ,,, Allison'd probably know better on this... You have three bootable devices... B DUA0 *RD5x in the box, never seen one external but it can be done. B MUA0 or 7 *tk50 tape I forget the device number as it's slow. B XQA0 *boot via eithernet. It was possible to run them diskless. B does the default device first (dua0) then tape then eithernet. Allison
