The Intel® Desktop Board VC820 supports either a single
Pentium® III processor at system bus
frequencies of 1 GHz, 133 MHz, 256 KB, P17 or greater, or a single
Pentium® II processor at a system bus frequency of 100 MHz. The
processor's VID pins automatically program the voltage regulator on
the desktop board to the required processor voltage. The system bus
speed of 100 MHz or 133 MHz is automatically selected. The processor
connects to the desktop board through the 242-contact slot connector.
Warning: Processors not specifically listed by type and
rated speed may have requirements that are not supported by the
desktop board's design. Use of unsupported processors may result
in improper operation, damage to the desktop board or processor,
or reduced product life.

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.
