***************************************************

Release: Thursday, September 9, 1999, v 5.00.2122.1 (DX/NX support)

Driver changes:

1. Driver refresh on Win98SE caused blue screen. Fixed a C++ static data member
that was not reset when driver was restarted in halfactory. This driver still
blue screens but the traceback is now in MS code. Waiting for MS to respond.

2. Rebuilt using Win2k DDK build 2122.

Release: Wednesday, September 8, 1999, v 5.00.2112.3 (DX/NX support)

Driver changes:

1. Driver removal caused blue screen. This was caused by deleting an interrupt
sync object in the midi uart dtor which has already been preformed in the wave dtor.

Release: Saturday, August 28, 1999, v 5.00.2112.2 (DX/NX support)

Driver changes:

Fixed bug in RevokeMapping where released memory was accessed.
Fixed bug in FillBusMaster where current mapping was null but silence
filling still happened.

Note: DO NOT RUN ACT Driver Verifier when running ACT's. Microsoft
has informed us to disable Driver Verifier or Wave Driver tests will FAIL.

Release: Friday, August 27, 1999, v 5.00.2112.1 (DX/NX support)

Driver and INF changes:

1.) This is our first snapshot driver. It contains necessary support
to pass WHQL ACT 99 v5.0 tests. This includes Mixer, Wave, Midi Uart.
This has only been tested under Windows 2000 RC1 build 2112.

WARNING: Windows 2000 releases prior to build 2112 are known to have
WDM Port Class driver problems. ACT's will not pass unless you
are running build 2112 or greater.

Good luck!
