If lspci doesn't show the PCI-PCI bridge, the i960 RAID card is using that internally. parisc (and any other architecture) should discover and configure all PCI-PCI bridges already. I know it did for the "multifunction" cards I had available 10 years ago. cheers, grant -- To unsubscribe from this list: send the line "unsubscribe linux-parisc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
