    Although it is not pin compatible with the Pentium, the Pentium Pro is backward code-compatible. Software written for previous HP Vectra PCs will run on the Pentium Pro-based HP Vectra PCs. Bus Frequencies Like the Pentium and 80486 DX2 processors, the Pentium Pro uses internal clock multiplication.

  • Page 25: Chip-Set

    Chip-Set The Intel 82440 FX chip-set comprises three chips. Two are concerned with controlling memory accesses. These are the data bus accelerator (DBX) chip (SB82442FX) and the combined PL/PCI bridge and memory controller (PMC) chip (SB82441FX). The DBX chip, controlled by the PMC chip, implements a 64-bit data path (not interleaved) between the Processor-Local bus and main memory modules.
