* If you want to install a Marc 2 PRO for the first time, then
  go ahead as follows:

  - Close the cover and switch on you computer.
  - Start Windows95/98 amd follow the instructions on the screen.
  - First, the Windows operation system may not find a driver, because it doesn't exists
    at the root directory of you installaton disk.
  - Search for the language directory of you choice und click "Ok."
  - Under Windows95b/c it may happens, that you have to choose the correct installation
    directory once again.
  - After you have installed the drivers, the Marc 2 PRO Sound System is ready for action.

3. What's new ?

Version 1.06:
* Non-Audio digital format added in "Marc 2 Pro Manager | Digital Output". 
  (useful e.g. for streaming AC3 audio to an external AC3 decoder)

Version 1.05:

* ASIO: performance improved when used with more than one card
* ASIO/GSIF: When using an ASIO/GSIF application, the driver overrides user's clock 
  nd start/stop synchronization settings with appropriate values.
  (these user settings are applicable for MME/DirectSound applications only).
  Now, the driver restores the user settings again, when the last ASIO/GSIF application
  has finished.
* ASIO/GSIF error "Failed in Kernelmode" solved.
* Marc 2 Pro Manager Software now uses the registry branch "HKCU" (User related) 
  to store it's settings.
* Marc 2 Pro Manager display error when using more than one card solved. 
* Start/Stop Synchronization of record and playback assured
* MME: synchronous buffer return improved
* Bug fixed: If the digital input "RCA" was selected, this setting now will be restored 
  after a windows restart.

Version 1.02:
Version 1.01 Beta:
* All :-)

4. Attention: Windows System Sounds

* After the first installtion of an audio device driver,
  Windows switchs on the Windows System Sounds per default.
  The system will playback these sound if a message box appears or
  a windows will be minimized or maxminized.
  The use of this system sounds may cause some problems in conjunction
  with running audio applications.

* Per default the driver takes care of a synchron start and stop of all
  devices of the Marc 2 PRO. This is a really important feature for
  each multichannel harddiskrecording program but it may cause conflicts 
  with the windows system sounds.
  If a running playback- or recording session will be interrupted by
  a system sound (because of a message box or window actions) the
  playback- or recording session will STOP too and the related audio
  application will hang (under specific circumstances) in a undefined state.
  You can solve this behavior by switching off the system sounds
  (Control Panel->Sounds) or by deactivating the Start/Stop
  Synchronization Option of the Marc 2 PRO driver. 
  (see Marc 2 PRO Manager - Settings - Synchronization)

5. Attention: Multicard Users

* If you get an error message at windows start which shows an harware
  initialization error, please remove ALL card from you computer and test
  each card alone. This is the only safe way to find out the defect card!
  Please request your hardware dealer to Exchange of the defect card 
  against a new one.

* NEVER disable or remove a Marc 2 PRO entry from windows device manager's
  list! This may cause problems in interaction with the Marc 2 PRO Manager
  and Driver. System crashs may be the consequence.
  This problem will be solved in the next driver update.

* Please install a driver update ONLY like described under 2.
