# IOResourceMatch

One or more system-specific or device-specific resources that your driver requires.

## Discussion

The value of this key is a string or an array of strings. Each string contains the name of a resource that must be published in the global resource list before the system loads the driver. For example, specify `IOBSD` to prevent the system from loading your driver until after the BSD kernel is available.

To access the list of global resources, call the <doc://com.apple.documentation/documentation/kernel/ioservice/1532617-getresourceservice> method of [`IOService`](https://developer.apple.com/documentation/kernel/ioservice-1g). To publish custom resources from your driver, call the <doc://com.apple.documentation/documentation/kernel/ioservice/1532848-publishresource> method.
