1. The first installation of the Marc 4 Digi an related drivers

* If you want to install a Marc 4 Digi for the first time, then
  go ahead as follows:

  - Switch off your computer and open the cover.
  - Put one or more (max. 4) Marc 4 Digi's into free PCI slots.
  - Close the cover and switch on you computer.
  - Start Windows95/98/ME and 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 4 Digi Sound System is ready for action.

------------------------------------------------------------------------------
2. Update from older drivers to this driver version

* If you have installed one ore more Marc 4 Digi(s) and related drivers so go ahead as follows:

  - Start Windows and remove the Marc 4 Digi entry from device managers device list.
    (recommend for users with one card only)

    O R

  - Start Windows in SAFE MODE
    (recommend for users with more than one card)

3. What's new ?

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 and 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.
* On some computers a driver error could stop recording and playback after appr. 1h.
  This error is solved with this version.

Version 1.04:

* Marc 4 Digi Manager Software now uses the registry branch "HKCU" (User related) 
  to store it's settings.

Version 1.03:

* Some Multicard-Support issues solved

Version 1.02:

* all ;-)

4. Notes: Digital Device Usage

  - ASIO User:
    Please note, that if you choose the "Digital Input" Device as active record device within the
    ASIO setup, then take care that your external digital device is connected, switched on and
    outputs a valid S/PDIF signal. The clock of this will be taken as reference clock for all
    active ASIO devices. If there is no clock present, you will not hear anything.

------------------------------------------------------------------------------
5. Notes: 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 4 Digi. 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 4 Digi driver.
  (see Marc 4 Digi Manager - Settings - Synchronization)

5. Notes: 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 4 Digi entry from windows device manager's
  list! This may cause problems in interaction with the Marc 4 Digi 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.
