SET DW
Copy the DW handler to DV and use the SET DV SLOT=n command to support the
PRO Expander. (Using device name DV is optional; you can use any device name
not recognized by or assigned to RT–11.) Use the SLOT=n option only to support a
PRO Expander and only with the created handler.
Use the SLOT=n option to identify the PRO Expander RD5x controller card slot in
the Professional’s backplane. The six card slots are numbered 0 through 5, from
front to back. The first RD5x controller is typically in slot 0. The second RD5x
controller typically goes in slot 5. Assuming that arrangement, issue the following
commands to support the PRO Expander:
.COPY SY:DW[X].SYS SY:DV[X].SYS
.SET DV SLOT=5
.INSTALL DV
