How to know if I/O range is reserved? And by whom?

    I have a PCMCIA device that uses a list of possible I/O to work, for
    example 1B8-1BF.
    This range does not appear on the device manager view by type in
    "Input/outpout (IO)" section but the device cannot start (code 12 :
    Windows cannot find enough resource) and the 1B8-1BF range is marked
    as not available.
    What could use this range ? BIOS ?
    Is there a way to list the I/O ranges that are occupied by Windows or/
    and BIOS ?

  2. In the kernel debugger, run !arbiters 1.

    How is the pcmcia device claiming the resource? Is it thru an INF file?
