No, that's not what that means.
It does say that micro diagnostics are required; when those are disabled, the
device is rejected because of that failure.
However, it also says that "XM0: is missing ECO's, but will still function."
That means the device is enabled, and it should be there and work when you
start the system. More precisely, if it doesn't work that would be for a
different reason.

Tried what with QBus? DMC? Only a DMV is valid on Qbus.
Mark, here is the code from the RSTS INIT code that generates the "missing
ECO's" message. I'll take a look at why it doesn't like DMR11s.

.SBTTL Check the Micro-code for latest ECO level
