ABSTRACT:
A method for accessing a main resource descriptor for a hardware device. A device driver accesses a hardware device's partial resource descriptor of a translated main resource descriptor stored in an operating system registry. The device driver accesses raw BIOS-assigned configuration information for the hardware device. The device driver compares the memory address in base address register0of the partial resource descriptor to the memory address in base address register0of the BIOS-assigned configuration information. The device driver selects the translated main resource descriptor that contains the partial resource descriptor with the memory address in base address register0that matches the memory address in base address register0for the raw BIOS-assigned configuration information.
