They DMA a small program into memory Ah, I was wondering about that, because there aren't any separate boot ROMs on the DEUNA. I bet the "small program" is just part of the T11 code. And I'm assuming that this scheme didn't work on any UNIBUS VAXes - only PDPs. I'd assume so as well. On a semi-related note, wasn't it not possible to netboot a UNIBUS VAX with a DEUNA? I seem to recall that from the manual. It required an intermediate bootloader or something, right? Unibus VAXen basically means VAX-11 machines. They booted either from VMB on console media, or (for the 11/750) from a boot block. No network capabilities there. They could not even boot from tape. Johnny Really? Not from tape?
