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.
