<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.
