I assume you mean you've built Standalone Backup on your system disk
in root [SYSE].

Close.   The command is:

>>>B/E0000000  ddcn

where ddcn is the optional device specification.  The value after the
"/" is just the hex value stored in register R5 (can also be specified
as >>>B/R5:xxxxxxx).  As such, the top 4 bits of R5 (as passed to VMB)
specify the root to boot from.  The interpretation of R5 is the same
for all VAXes.
