Jerome Fine replies:

In a BA123 box, all the drives are set to DS3 and the I/O distribution board
in slot 13 manages the rest. But, if the RD54 is the second drive in a BA23
box (rare but possible in a 6 switch front panel), then you must use DS4.

This arrangement was VERY FIRMLY impressed on my memory one day
about 10 years ago when I had just done a format of an RD52. Just to
be careful, I removed the first RD52 drive before I did the format for the
second drive. After it was done, I put the first RD52 back into the system, but
forgot to set the second drive to DS4. I wound up with both RD52 drives
requiring a format - and lost all the files from the first RD52.

Sincerely yours,

Jerome Fine
