   I know this
has been discussed before, but I can't find the info. I just
 aquired a Maxtor 2190 disk drive that I want to convert into a DEC RD54. I
 know about formatting it under XXDP, but I remember that a jumper had to be
 changed on the drive. Can anyone help me out here?  You need to reset the jumper to
DS3. 
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
