Remember just > because it's on the motherboard doesn't mean it's a non-PCI device. Compare the output of acpidump and the datasheet for a Super I/O chip some time. Everything on the LPCB is legacy and is thus probed through ACPI, not PCI. IRDA is almost always on the Super I/O. http://www.via.com.tw/en/Products/superIO.jsp -Nate ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
