Contains information about the I/O descriptors. The full descriptor consists of this structure and an array of IO_RANGE structures.

IOD_Count

Number of IO_RANGE structures in this resource descriptor.

IOD_Type

Size, in bytes, of each IO_RANGE structure in this resource descriptor.

IOD_Alloc_Base

Allocated base port address.

IOD_Alloc_End

Allocated end port address.
