Yes, although it is very platform specific -- there are actually transistors in the pci bridge chip, which actually short out lines, and so, from the point of view of the rest of the chip, it did actually see a "real" error. Its supposed to be a very realistic test. > I've been vaguely musing a PCI device failure patch for > x86, just so people can test driver failure paths. That would be good ... I've recently agreed to accept a fedex to test someone elses card for them, which is outside my usual activities. There's also supposed to be some PCI-X riser card out there, (never seen one) which has the ability to inject actual pci errors. Its the Agilent PCI BestX card; I got the impression they might not sell it anymore; dunno. One guy in the lab used to brush a grounding strap across the pins; this usually got a rise out of the audience. --linas
