+## Raising Custom System Event Trigger
+
+Demonstrates how to register background task with the CustomSystemEventTrigger type and
+raise a custom system event when an OSR FX-2 device is connected to a system. The code to
+raise the event is part of the OSR FX-2 driver. This enables custom devices/NT services to raise a custom system event which triggers a background task.
+
+The code for the OSR USB FX-2 driver can be found in the
+[Microsoft Windows-driver-samples repo](https://github.com/Microsoft/Windows-driver-samples/)
+under
+[usb/kmdf_fx2/driver](https://github.com/Microsoft/Windows-driver-samples/tree/master/usb/kmdf_fx2).
+The driver must be built for Windows 10 version 1803 or higher in order to support
+the custom system event trigger used by this sample.
+
+## Firmware access
+
+Declaring the restricted capability `smbios` allows apps to read the SMBIOS.
+Call the
+[GetSystemFirmwareTable](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724379(v=vs.85).aspx)
+and
+[EnumSystemFirmwareTables](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724259(v=vs.85).aspx)
+functions with the 'RSMB' (Raw SMBIOS) table provider.
+
+The following custom capabilities can be used for accessing UEFI variables:
+
+- `microsoft.firmwareRead_cw5n1h2txyewy`: Read UEFI variables using [GetFirmwareEnvironmentVariable](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724325(v=vs.85).aspx)
+- `microsoft.firmwareWrite_cw5n1h2txyewy`: Read/Write UEFI variables using [SetFirmwareEnvironmentVariable](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724934(v=vs.85).aspx)
+
+UEFI access also requires the app to declare 'protectedApp' restricted capability and enable [INTEGRITYCHECK](https://docs.microsoft.com/en-us/cpp/build/reference/integritycheck-require-signature-check) for the project. This would trigger necessary store signing for protected apps during store submission. Currently the [INTEGRITYCHECK](https://docs.microsoft.com/en-us/cpp/build/reference/integritycheck-require-signature-check) can only be enabled on C++ projects properties.
+
+UEFI variables can be accessed only when the app is being used by a user belonging to Administrators group.
+
 **Note** The Windows universal samples require Visual Studio 2017 to build and Windows 10 to execute.
