I've got the chip specs. for all the functions, but I'm having some trouble with the application. I don't want to go through a lot of trouble re-inventing the wheel, so I'm checking to see if there is any source code available. Anything, even sample routines, would be greatly appreciated.

IBM used to publish the source to their BIOS a long time ago, and programmers could get it fairly easily several years ago. Of course this was back in the DOS 2.11 days. *********************************************************************** Earl W. Bollinger @ "You were in the Clone Wars!", said Luke excitedly.
