  Is there a potential problem here?

 I have an 11/53 microPDP11 with a RQZX1 controller connected to a single
 DEC DSP3043 drive (535MB) and a single RX33 floppy.

 The autoconfigure setup in the RQZX1 puts the hard disk at DU0 and the
 Floppy as DU1.  OK.  I boot RT11 from the disk, V5.7. Works fine.

 I would like to use some of the extra space on the disk by setting up
 RT11 disk partitions.

 However, one of the partitions is DU1, but that is what the Floppy is
 called.  How do I stay away from what seems like a conflict?

 Doug  SET DU2: UNIT=0,PART=1
 SET DU3: UNIT=0,PART=2

 ** reboot **

 INIT DU2:
 INIT DU3:

 Thanks, it did work. I'll just stay away from DU1:.? I forgot about the 
reboot required for these changes to take effect.
