CPU Board
The CPU board carries two sockets to support a powerful dual-CPU
configuration. The sockets accommodate the new Intel Pentium II
CPU running at 233/266 MHz. The Pentium II CPU incorporates the
first-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 both
fast-page mode and 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.
