Device-direct I/O is available under FILDDT. Do it from the console login so
that you're properly 1,2. If you run FILDDT and type /H to its prompt, you
will see what the options are. Basically, you want something like RPA0:/U to
start, and remember to multiply every sector number by 200 (octal) to get the
disk address right. The HOM blocks are sectors 1 and 12, so their addresses
are 200 and 2400 respectively.

Since DEC never supported SCSI hardware (that was done independently by SC and
XKL at different times for different hardware), that's never going to work.
I don't have an SC install manual, so I can't begin to guess how to boot from
