I.  Overview
---------------------------

A.  SYSTEM REQUIREMENTS:

	1.  Windows NT 4.0 PC with:
	    * Pentium 166MHz or faster CPU
	    * 32MB DRAM
	    * Available PCI slot.
	    * Windows NT installed.

B.  NEW FEATURES:

   1.  Added Stereo X2 Quad Support
   2.  Added support for Sigmatel 9208 Codecs
  
C.  WINDOWS NT 4.0 DRIVER ISSUES:

   1.  BIOS Settings - For proper operation, any BIOS support for 
       "Plug and Play OS" or "Windows 95 OS" must be disabled. The NT 
       drivers attempt to configure the audio card if the BIOS setting 
       is set correctly, but are not successful on all machine types.

   2.  Matrox Display Adapters - The Matrox drivers shipping with NT 
       4.0 are poorly behaved in the system and hog the PCI bus during 
       heavy graphics usage, which can cause noticable audio dropouts. 
       If using Matrox Millennium II driver v3.20, (4.0.55), try 
       upgrading to the latest Matrox drivers. Upgrading to the latest 
       driver will not guarantee any improvement.  In this case, you 
       may want to contact Matrox directly to address this problem.

   3.  Number Nine Display Adapters - The Number Nine Imagine128 
       drivers shipping with NT4.0 are poorly behaved in the system 
       and hog the PCI bus during heavy graphics usage, which can 
       cause noticable audio dropouts. 

   4.  Riva 128 Display Adapters - The Riva 128 drivers shipping 
       with NT4.0 are poorly behaved in the system and hog the PCI bus 
       during heavy graphics usage, which can cause noticable audio 
       dropouts. A new set of drivers for Riva128 display adapters
       fixes the problem and is available from:

       http://www.stb.com/drivers/velocity/vl128.html

   5.  3COM network card drivers - Version 1.0 of the XL 3COM network 
       card driver found on the NT distribution CD can cause blue 
       screens during installations. Be sure to use 1.1 or above.
