I'm looking at this right now :) Looks very useful, thanks! Just one more question to clear a little confusion on my side, the device that i'm trying to write/port driver for is a cardbus device. Do i have to do something specific about this, or can i get away with accessing/using it as a plain PCI device? (yes, it appears as pci device to the system, and is shown in pciconf) Thanks again! --niki
