Chapter 2. System board features
This section includes information about system board features. For an illustration of the system board,
see “System board, types 6268, 6278, and 6288” on page 13.
Celeron microprocessor with MMX technology
PC 300GL Types 6268, 6278, and 6288 comes with an Intel Celeron microprocessor. The
microprocessor, which has a heat sink attached, plugs directly into a connector on the system board.
More information about this microprocessor is available at http://www.intel.com on the World Wide Web.
