If you're running an NT-based system, it is not possible to directly
access the OPL chip, even when running as Administrator. Fortunately,
-it is possible to use the third-party "PortTalk" driver:
+it is possible to use the "ioperm.sys" driver developed for Cygwin:
- http://www.beyondlogic.org/porttalk/porttalk.htm
+ http://openwince.sourceforge.net/ioperm/
-TODO - the NT driver hasn't actually been written yet..
+It is not necessary to have Cygwin installed to use this. Copy the
+ioperm.sys file into the same directory as the Chocolate Doom
+executable and it should be automatically loaded.
