      Plug and Play
      =============
      
      Plug and Play (PnP) is a new system architecture for ISA bus
      computers that automatically configures PnP hardware devices, such
      as your NodeRunner Pro(TM) adapter, when you turn on the
      computer.
      
      Currently, two types of computers can be called "Plug and Play."
      The first type has a PnP BIOS, while the second type doesn't. Both
      types need a PnP Configuration Manager (CM). When you buy a
      computer with a PnP BIOS, it should come with a CM. If it doesn't,
      contact your computer vendor.
      
      A Configuration Manager is a DOS based program (a device driver)
      that controls system resource assignments such as IRQ and I/O
      address. The CM functions as a backup to the PnP BIOS -- it
      configures any system resource that the PnP BIOS doesn't assign.
      
      In the case where you don't have a PnP BIOS, the CM configures all
      the system resources.
      
      For both computers, install the adapter according to the
      instructions in your Installation Guide.
      
      
      Computers with Plug and Play BIOS (recommended)
      ===============================================
      
      The ideal Plug and Play computer has a PnP BIOS and a PnP
      Configuration Manager. The PnP BIOS automatically configures your
      NodeRunner Pro adapter when you turn on your computer (before
      the operating system starts).
      
      You can view or modify your adapter's configuration using NProSet
      or the Configuration Manager's ISA Configuration Utility (ICU). For
      more info, see "Locking the configuration" and "Changing the
      configuration" at the end of this file.
      
      If you have a Plug and Play BIOS and are running OS/2*, Windows
      NT*, or a NetWare* server, make sure you DISABLE Plug and Play on
      your adapter using NProSet (Advanced Options menu). Having Plug
      and Play enabled may cause configuration problems because these
      environments don't support Plug and Play (they don't support a
      Configuration Manager.)
      
      
      If you have Flash
      -----------------
      
      After the PnP BIOS configures the adapter, the Flash memory
      receives control before the operating system loads. Flash updates
      the adapter's default system resources (such as IRQ and I/O
      address) with the values the PnP BIOS assigned.
      
      Warning: Disabling Flash cancels this updating process.
      
      
      Computers without Plug and Play BIOS (not recommended)
      ======================================================
      
      If you want PnP features without a PnP BIOS, you must have a
      Configuration Manager. The CM automatically configures your
      NodeRunner Pro adapter when DOS boots.
      
      This type of computer isn't recommended for a file server because
      the CM is DOS/Windows based and won't work in other environments
      such as Netware or OS/2.
      
      
      Locking the configuration
      =========================
      
      Every time you add a Plug and Play device to the computer, the Plug
      and Play software re-analyzes the system and may assign a new I/O
      address (or other system resource) to the Plug and Play devices
      you've already installed.
      
      In most cases, this isn't a problem. But when you have more than
      one NodeRunner Pro adapter installed, the network driver uses
      the I/O address to identify each adapter. If Plug and Play assigns
      a new I/O address to the old adapter, the network driver won't be
      able to find the adapter.
      
      To make your adapter's I/O address permanent, use the Configuration
      Manager's ISA Configuration Utility (ICU) to lock the
      configuration.
      
      
      Changing the configuration
      ==========================
      
      If you don't want to accept the configuration settings that the PnP
      BIOS or PnP CM chose for the adapter, you can disable Plug and Play
      on the adapter and configure the adapter yourself.
      
      You need to disable Plug and Play if you're running OS/2, Windows
      NT, or a NetWare server.
      
      1  Insert the Configuration disk into a drive, switch to that
         drive, and type NPROSET.
      
      2  From the main menu, select CHANGE ADAPTER CONFIGURATION.
      
      3  Select ADVANCED OPTIONS, then PLUG AND PLAY, then DISABLE.
      
      4  Return to the Change Adapter Configuration menu, select the
         configuration settings you want, and press F10 to save those
         settings.
      
      
      Troubleshooting
      ===============
      
      If Plug and Play doesn't seem to be working, NProSet can help you
      isolate your problem.
      
      From the NProSet main menu, select VIEW ADAPTER CONFIGURATION.
      
      Look for the "Plug and Play version" entry and use the following
      table to get more information about your computer's Plug and Play
      configuration.

      X.XX                       This is the version number of your
                                 PnP BIOS.
      
      PnP BIOS only              You have a compliant PnP BIOS, but no
                                 Configuration Manager. Contact your
                                 computer vendor to get a CM.
      
      Noncompliant PnP BIOS      Your computer's PnP BIOS isn't Plug and
                                 Play compliant. Contact your computer
                                 vendor and see about getting a new, PnP-
                                 compliant BIOS.
