	I just checked and the V3.2 distribution disks on bitsavers are RL02 images (even if
	they are in the RL01 directory). The baseline image is an unmapped system which is
	a bit restrictive for your 11/40 but there is a full mapped system on the disk. To make
	the mapped system the default:

	1. boot the baseline unmapped system as Mark showed below. Make sure your
	    system is configured as an 11/40.

	2. type the following at the “>” prompt

		ins $boo
		boo [1,54]rsx11m

	  this will boot up the mapped system.

	3. to make this the default (after the acs command wait for a response that the
	    checkpoint file is inactive):

		acs sy:/blks=0
		sav /wb

	now you should have a bootable mapped system which you can copy to your
	physical RL02. Depending on the state of your EIS board you may want to
	stay with the original unmapped system - I suspect that the baseline mapped
	system will always try to use the “sob” instruction.
