Chapter 2 CPU Board
The CPU board carries two sockets to support a powerful dual-CPU configuration.
The sockets accommodate Intel Pentium II CPUs running at 266 MHz or 300 MHz
and incorporates the first-level and second-level cache and boasts a new
generation of power.
The board comes with four DRAM banks composed of four 168-pin dual-inline
memory module (DIMM) sockets that accommodate ECC/EDO (extended data
output) DIMMs.
Designed to work with Intel 440FX PCIset, the board includes the PCI
bridge/memory controller (PMC) and the data bus accelerator (DBX) chipsets.
The PMC provides bus control signals and address paths for transfers between the
host bus, PCI bus, and the main memory. The DBX supports multiple-bit error
detection and single-bit error correction through the ECC/parity feature.
