He has specifically determined, and Dell has even admitted to me in chat and phone support, that the BIOS does not implement the features necessary for the hotplug support that the hardware supports. This is complete Dell, this is not what I wanted when I bought the hardware. Sure, maybe XP does work, but that is because it does not use the correct method because XP does not natively know anything about pci-express. However, Vista specifically _does_ use the correct _OSC method in order to hotplug pci-express devices (aka many expresscard devices). If you don't believe me, go read http://www.microsoft.com/whdc/system/bus/pci/BIOS_HotPlugPCIe.mspx which is a very good whitepaper. /Mikael > > > /Mikael > -- Plus ça change, plus c'est la même chose ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
