Board Revision note: A small bar-coded label, similar to the diagram
shown below, can be found on the component side of the desktop board. The numbers following the
letters "AA" can help identify the type and version of your desktop board. The AA contains a 6
digit main number, and a 3 digit dash number (the 3 numbers following the "-".
The statement "...or later" refers to the dash number of the AA (the three numbers following the
"-"). If this number is greater than the number listed in the table, the board supports the
associated processor(s).
If your 6 digit main number is not listed in the table, contact your system manufacturer for
processor support information.
