This sequence of simh-vax commands auto boots (as it should)

        load -r ka655x.bin
        set cpu 128m
        ... extraneous stuff deleted ...
        dep -b BDR 0
        boot cpu

but this doesn't -

        load -r ka655x.bin
        set cpu 48m
        ... the same extraneous stuff deleted ...
        dep -b BDR 0
        boot cpu

You don't get any errors, but instead of auto booting the MicroVAX firmware
just stops at the >>> prompt.

  It looks like the BDR setting only works if the CPU is "extended" with
more than 64Mb of memory.  That doesn't seem right - certainly a real
MicroVAX would be able to auto boot under these circumstances.  Am I doing
something wrong, or is this a bug?

Thanks,
Bob Armstrong
