It appears that the distribution there was only meant for a dual-RX50 MicroVAX 1 with an RD drive, and will not boot on any other machine. RQ0 needs to be an RD51 or RD52, and RQ1 and RQ2 need to be RX50s. TTI and TTO need to be 7 bit. To boot the installer, put 32m-1.0-bin/01 on RQ1 and 32m-1.0-bin/02 on RQ2. The install goes cleanly, albeit with quite a bit of disk swapping - the installation disk set is 13 floppies.<o:p></o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'>The QVSS is supported and will display some output on boot. I haven't yet looked into what is needed to use it as the console (if that's possible?).<br><br>The kernel seems to support what I assume is the DEQNA - it has references to a qe device - but I can't figure out how to get it recognized. Unfortunately there are no kernel config files in the distribution, so I have no idea if the stock kernel is expecting the controller at a non-standard address. Any help with this would be greatly appreciated, <o:p></o:p></p></div><p class=MsoNormal>-Henry<o:p></o:p></p></div></div></div></body></html>
