Revision Information

By scanning and manipulating the STX104 registers one can determine the firmware revision that is installed.

Revision Releases

Date	Revision ROM Label	Board ID Register Value
July 16, 2004	071604	Does not exist
February 14, 2008	080214H	0x1008
April 4, 2008	080407H	0x1008
January 15, 2009	090115H	0x1009

Note:

1. Revision 080214H has been replaced by 080407H including boards in the field effectively eliminating the 080214H revision entirely. Revision 080407H corrects for several minor issues that were discovered in revision 080214H which does not warrant a change to the board ID.

2. Revision 090115H added mapping the 8254 registers through the index register set to improve accessibility by driver software.
