Configuring the System Board
Configuring the System Board
This section contains information to help you properly configure the system board.
Features
The 64-bit, high-performance system board supports both the Intel Pentium™ and Pentium Pro™ microprocessors (also called CPUs). However, to provide maximum upgradability and flexibility, the microprocessors are not installed on the system board.
Instead, the system board has a special slot designed to accommodate a separate CPU board. This dual-processor CPU board contains both microprocessors and the embedded 512 KB pipeline burst second-level cache. See the section, “Installing CPU Boards,” in Chapter 3 of this manual.
Standard features such as a video port, two serial ports, one parallel port, diskette drive interface, and embedded fixed disk drive interface reside on the system board.
The system board has a 0 MB base memory and supports a maximum memory of 512 MB using 64 MB single-density single inline memory modules (SIMMs). A functional system is recommended to have at least 16 MB of RAM.
Major Components
The system board has the following major components:
∙Eight 72-pin SIMM sockets labeled Bank 0, 1, 2, and 3 (two sockets comprise one bank) that support single- and double-density 60/70 ns SIMMs
∙One CPU board slot
∙Two 32-bit EISA expansion slots supporting master/slave add-on cards
∙Four PCI local bus slots
