Microprocessor Board

The microprocessor board contains the high-speed components: the microprocessor, backside cache, main memory, system ROM, and the IC that contains the memory controller and the PCI bus bridge.

The Microprocessor board has two memory card slots. The top slot is the user- replaceable slot. The slot on the underside of the board is used by the factory.
