			Windows 3.1x Driver Package

				Release V1.52, 15 Aug 1996

Release notes

This version of the AD1812 Win31 drivers improves over the V1.0 drivers by 
adding support for the XCTL0 and the XCTL1 pins. Developers can now write
applications that directly control spatializers, such as QSound's, through
these pins.

This version also provides a much more user friendly SETUP.EXE program, that
lets the user opt for an installation with default settings, or for an 
installation with customized resource settings.

It further improves on older versions by fully detecting whether the AD1812
is enabled in PnP or non PnP mode on the board. When enabled in PnP mode and
running Win95, the user can still default back to Win31 without having to
change the AD1812's jump setting.

This version will compatible with the ICU (Intel Configuration Utility) for
non PnP BIOS mother-board. You can run the ICU dos configration utility to
setting the PnP resource. We recommend the customer to setting the same
resource for the AD1812 during install the AD1812 win3.1 device driver and run
the ICU dos configration utility.

This version also reduced the TSR memory requirement.

Sound Blaster DOS games. When Win3.1is started, this utility will 
automaticly switch to the Windows Sound System mode. When you 
exit from Win3.1, it will automatically switch back to Sound Blaster mode.

Trouble shooting

In Win3.1 it's possible a hardware conflict occurs, that crashes the system.
In such case, manually remove the TSR PnP utility in the autoexec.bat file, and
run the hwsetup program again. Alternatively, you can take out the board and run 
the setup program again with other choices of I/O resources.
