2) Installation
   ============

    In a Windows 2000 enviroment the DataFire boards 
    are automatically detected by the hardware wizard. This 
    software starts the ISDN wizard (part of the Windows 
    2000 system) and the installation will start.  
    To install the driver software for the DataFire adapter simply 
    follow the steps displayed on the screen.
    For further details please refer to the manual for your DataFire board.
    
    If you want to configure the adapter (concerning the 
    D-Channel protocol), go to 'My Computer' icon on your 
    desktop, click the right mouse button and activate 
    'Properties', click to 'Hardware' and start 'DeviceManger':
    Under 'Network adapters' you will find in here your 
    installed DataFire adapter. Go to this entry
    and click again the right mouse button and start 'Properties'.
    On 'Advanced' and 'ISDN' you will find the places to take the
    DataFire adapter configuration.

    For more details see the manual.


3) Driver update
   =============

   If you want to update the installed driver please proceed as follows:
   Go to the Hardware tab of the "System Properties" dialog of 
   Windows 2000, click on "Device Manager" and select the installed 
   Digi ISDN card. Click the right mouse button and choose "Uninstall...". 
   After the current driver is deinstalled click the button 
   "Hardware Wizard..." on the Hardware tab. 
   The Digi ISDN adapter will be found by this routine and you have to 
   specify the path where the new driver is located.
   After this follow the procedure as described in chapter 2.


4) CAPI 2.0 Driver
   ===============

   The Windows 2000 CAPI 2.0 Interface supports the
   interfaces for 16 bit programs (capi20.dll),
   32 bit programs (capi2032.dll) and kernel mode
   drivers.


5) WAN Miniport Driver
   =================== 

   This ISDN card driver package contains a NDIS 4.0 
   WAN Miniport driver that can be used for dial-up 
   networking under Windows 2000.

   The WAN Miniport parameters can be configured on the 
   "Advanced" property page of the ISDN adapter.
   Click on the "WAN parameters" button.
   These items concern remote access connections in general.
   

6) Notes for using PCMCIA Adapter
   ==============================
  
   If you have registered an application on the CAPI interface
   you do not need to reregister after having plugged in the 
   adapter again respectively after wake up from standby-mode.
   In this case you should notice that a connection will be
   discontinued and needs to set up again.


7) Power Management
   ================
   This driver package supports Hibernate and Standby functionality 
   on Windows 2000 systems.
   The DataFire Micro V supports "Wake-On-Ring" via #PME on the PCI
   bus with all power states including D3-cold if the Motherboard 
   supports the ACPI standard.   

   "Wake-On-Ring"   
   --------------
   The DataFire Micro V supports the ACPI (Advanced Control and 
   Power Interface) standard and additionally "Wake-On-Ring". 
   This feature enables ACPI compliant systems both to wake up 
   the PC from standby mode on incoming telephone calls or faxes 
   and to accept the calls and fall back into the standby mode again 
   as soon as the calls are finished.
   It allows the system to accept incoming calls or faxes while 
   running on standby mode at reduced power consumption.
   
   Power States:
   Under Windows 2000 the following power states are supported by 
   the DataFire Micro V. They can be configured in the ACPI settings 
   of DataFire Micro V.The ACPI settings of DataFire Micro V do only 
   configure the DataFire Micro V card itself but do effect the 
   behavior of the complete system.
   
   S1:  Standby
   The standby support is the default parameter of DataFire Micro V 
   after installation. To use this function the complete system has 
   to support the ACPI standard. This means, that the BIOS of the 
   system and all installed components have to be ACPI compliant. 
   When forced to the standby mode the system will power down the 
   PC to power state S1 (standby). Forcing the system to standby mode 
   can be done manually within the Taskbar with items 
   Start/Shut-down/Standby or scheduled over the power management settings 
   in System/Control Panel. At present, S1 is the only power state that 
   supports the "Wake-On-Ring" feature if activated in the DataFire Micro V 
   "Power Management" tab and if there is a "listen"-functionactivated by 
   an application which is listening for incoming calls.

   S3: Suspend-To-RAM
   If this feature is enabled and the system falls into standby mode the 
   entire memory contents are written to the RAM (Random Access Memory). 
   This allows the system to work on a low power consumption level.
   To use this feature the system has to support the "Suspend-To-RAM" (STR)
   function for the standby mode. This setting can be configured in the BIOS 
   power management section of the system.
   Note: Till now the S3 power state can not be used for the "Wake-On-Ring" 
   function because the PC does not wake up fast enough to accept an 
   incoming call. Microsoft is aware of this problem and has found a 
   "Fast Boot PC" initiative with the goal to decrease the time the PC 
   needs to wake up from the S3 mode.

   
   S4: Hibernate 
   If this setting is activated in the DataFire Micro V driver 
   software and the system falls into standby mode the entire memory 
   contents are written to the hard disk (Suspend-To-Disk). To use this 
   feature the complete system has to support the ACPI mode for Hibernate.
   The Hibernate mode allows the system to run on a very low power 
   consumption level but is not an appropriate mode for the "Wake-On-Ring" 
   functionality because the PC does not wake up fast enough.

   
   System Requirements for Wake-On-Ring:
   To use the "Wake-On-Ring" functionality the following 
   requirements have to be met:

   1) The motherboard has to support the ACPI standard 
      and the Standby function.
      These settings can be configured in system BIOS 
      in the Powermanagement section of these systems.

   2) The operating system has to support the ACPI standard and 
      the standby function. At present this is realized in Windows 2000 
      only and planned for Windows Millenium. The ACPI support of 
      Windows 98 SE that can be enabled in the registry is not officially 
      supported by Microsoft and therefore not applicable. In Windows 2000 
      the "Standby" mode can be configured in different ways. One way is 
      to do this manually over items: Start/Shut-down/Standby. 
      This causes the PC either to fall back into the standby mode until an 
      incoming call wakes up the PC or to become activated by a keyboard 
      shortcut configured in the system BIOS.
      In addition to that the system can be configured to use the standby mode 
      under items My Computer/Control Panel/Power management /Standby. 
      The settings allow to activate an inactivity timer which forces the 
      system to fall into the standby mode as soon as there isnt an active 
      call any longer.
  
   3) To use the standby function all components like graphic adapter, 
      hard disk, sound card, etc. have to support the ACPI standard. 
      If one of the components does not support ACPI the standby feature 
      will not be offered by the operating system.
      Furthermore, the capability of the "Wake-On-Ring" feature to accept 
      incoming calls in time, depends on the period of time the system needs 
      to wake up from the standby mode. The wake up time itself is basically 
      depending on the installed hardware components 
      (hard disk, graphic adapter, sound card, etc.).

   4) Concerning the ISDN line and the "Wake-On-Ring" feature 
      please note the following:
      The DataFire Micro V reacts on a change of layer 1 state of the 
      ISDN bus. Because of this it is required to run the DataFire Micro V 
      on an ISDN bus with a non permanent layer 1.
      This layer 1 is deactivated as long as there is no active call on the 
      ISDN bus. In case of an incoming call layer 1 of the ISDN bus will be 
      activated and the DataFire Micro V thereby can cause the PC to wake up 
      from standby mode. After finishing the call layer 1 will be 
      deactivated automatically by the telephone switch after a short period.
      Note: Till now there is no way to check whether an incoming call is 
      directed explicitly to the software applications of the 
      DataFire Micro V card or to any other device on the same ISDN bus. 
      So the DataFire Micro V will wake up the PC even if the call was 
      directed to a device outside the PC (e.g. a telephone or a fax) but 
      on the same ISDN bus. In addition to that all other devices 
      (telephone, fax or other ISDN cards) will bring up layer 1 
      if they generate an outgoing call. In this case as well the 
      DataFire Micro V will wake up the PC because layer 1 of the 
      ISDN bus has been activated.
