"Each PCI Express Link is equivalent to a logical PCI bus. In other words, each Link is assigned a bus number by the bus enumerating software. A PCI Express endpoint is device 0 on a PCI Express Link of a given bus number. Only one device (device 0) exists per PCI Express Link." -- PCI Express System Architecture, p. 51 --Ed -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
