- \r
- This function checks to see if a controller can be managed by the ISA Bus \r
- Driver. This is done by checking to see if the controller supports the \r
- EFI_PCI_IO_PROTOCOL protocol, and then looking at the PCI Configuration \r
- Header to see if the device is a PCI to ISA bridge. The class code of \r
- PCI to ISA bridge: Base class 06h, Sub class 01h Interface 00h \r
- \r
- Arguments:\r
- \r
- This - The EFI_DRIVER_BINDING_PROTOCOL instance.\r
- Controller - The handle of the device to check.\r
- RemainingDevicePath - A pointer to the remaining portion of a device path.\r
-\r
- Returns:\r
