+*  Module Name:       Realtek 8019AS Driver
+*  
+*  Created By:        Louis Beaudoin (www.embedded-creations.com)
+*
+*  Original Release:  September 21, 2002 
+*
+*  Module Description:  
+*  Provides functions to initialize the Realtek 8019AS, and send and retreive
+*  packets
+*
+*  September 30, 2002 - Louis Beaudoin
+*    Receive functions modified to handle errors encountered when receiving a
+*      fast data stream.  Functions now manually retreive data instead of
+*      using the send packet command.  Interface improved by checking for
+*      overruns and data in the buffer internally.
+*    Corrected the overrun function - overrun flag was not reset after overrun
+*    Added support for the Imagecraft Compiler
+*    Added support to communicate with the NIC using general I/O ports
