Hermès Bélusca-Maïto d25d9ea618 [NTVDM] 
- Enable experimental sound support (only PC speaker for the moment, aka. uses beep.sys).
- Introduce a #define WORKING_TIMER which aim is to disable the currently problematic approximate performance counter value calculation done in order not to call QueryPerformanceCounter each time.
  The problem is that we then compute a number of clock ticks for the PIT, which becomes negative, and therefore everything starts to hang.
  Disabling this code and calling each time QueryPerformanceCounter, fixes everything; we gain in precision but we loose in performance...
  A definitive fix must be found, [TheFlash] !!

This fixes sound (and hangs) in Advanced NetWars, Dangerous Dave, ElitePlus and Rescue Rover (the games that I've tested so far).

========================
ReactOS Version 0.3.x
Updated Dec 16, 2006
========================

1. What is ReactOS?

   ReactOS is an Open Source effort to develop a quality operating system
that is compatible with Windows NT applications and drivers.

   The ReactOS project, although currently focused on Windows XP/2003
drivers compatibility, is always keeping an eye toward compatibility with
older version of Windows NT family ( NT 4.0, 2000 (NT 5.0)) and new
Windows NT releases (Vista, etc). Applications (Win32 API) compatibility
focus is Windows XP.

More information is available at http://www.reactos.org/.

2. Building ReactOS

See the INSTALL file for more details.

3. More information

See the media\doc subdirectory for some sparse notes.

4. Who is responsible

See the CREDITS file.
