It doesn't exist. The list is published in more than one of the
manuals, for example it's in the Micro PDP-11 Maintenance Manual.
Here's the list Roger Wallace posted to vmsnet.pdp11 many years ago.
It's valid for all the -BE to -BJ versions, with the caveats that the
TMSCP boot is only present in the last versions, older versions don't
support later hard drives, -BE doesn't support TSV05/TK25 or the MSCP
sniffer boot.
If S1-1 to S1-6 are all open, autoboot is disabled; if they're all
closed, the self-test loops (and does not autoboot, of course). The
MSCP sniffer boot first tries all removable-media MSCP devices, then all
fixed MSCP devices, and boots from the first it finds with a valid
bootstrap.
======================================
S1-8: Console Select -- ON = ANSI CRT (e.g. VT-100)
OFF = NOT ANSI CRT (Hard copy TTY)
S1-7: Memory Diagnostic -- ON = Run Quick Memory Diagnostics
(But the system seems to run this anyway, even
with the switch OFF)
S1-1 through S1-6: Select Boot Device as follows (0=Open/1=Closed):
S1 6 5 4 3 2 1 *** Device ***
0 0 0 0 0 1 TSV05 Unit0 (TK25)

Other possible combinations are "reserved" or "unused".
With luck 8-} , I copied these correctly from by KDF11BJ ROM upgrade kit
manual. The DU: "Sniffer Boot" was the default for DEC Micro-11 systems;
it tests _removable_ MSCP devices, then _fixed_ MSCP devices, in
numerical order and boots the system from the first bootable device found.
