#menu# install a DDA device into the VP/ix Environment
#help#
#help#  This procedure allows you to "register" an add-on board for
#help#  Direct Access in the VP/ix Environment (that is, without the
#help#  support of a specially-written device emulation module).
#help#  You should not attempt this operation unless you fully
#help#  understand how to install and configure add-on boards.
#help#
#help#  Once a device has been registered, VP/ix users may request
#help#  access to it by specifying its name in their vpix.cnf files.
