Charles,
are the boot ROMs DEC ones? I had similar problems with my 11/23+, and found
that the boot ROMs were OEM ones, and had completly different settings. I
have the options of network boot or RL01. All the other settings are for
application specific diagnostics.
You may find different versions of DEC boot ROMs have different switch
settings - all the switches do is set a start address in ROM that is
interpreted by the microcode.
Jim.
