Many current generation computers use the PCI configuration method and the 256 byte PCI configuration space memory required of all PCI-compliant devices to help set up and manage system chipsets and I/O peripherals. Using PCI configuration for a bus protocol such as HyperTransport goes a long way toward promoting software compatibility with the millions of systems already supporting buses employing PCI-based configuration, including PCI, AGP, PCI-X, USB, etc. HyperTransport is designed for PCI plug-and-play configuration and to minimize impact on existing BIOS and driver software. |
