I have no idea how to figure out where the ohci interrupt is vectored. It seems likely that it goes via ISA like the other pci functions on that device (IDE etc) but I don't know what interrupt number it would use without looking at the datasheet. Perhaps if you upgrade your firmware, a more recent SRM will program the intline with a better value than 255? -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
