Gents, How should a system behave if ???? -Frame# was asserted for a valid address -IRDY# asserted -DEVSEL# asserted -TRDY# never came down and the system hung..... Abnormalities in PCI targets are related to DEVSEL not responding but not TRDY#. Thanks. Monji Jabori Tel: 281-518-0552 Email: MonjiJ@netgate.compaq.com £ 0
