We have customised our WIndows 10 IoT Enterprise (1607) OS image to boot into the custom Shell Launcher rather than the standard Windows desktop. The Shell Launcher successfully runs our application and there are no UI elements with Windows branding displayed.
However there is a long period of time (~15-20 seconds) during which a black screen is displayed. This time occurs after the BIOS splash screen disappears and prior to our Application being launched (launching our application takes <1sec).
The boot sequence we observe is as follows:
- BIOS splash screen is displayed (~5-10 seconds).
- Black screen is displayed (~15-20 seconds).
- Application UI is displayed
This behaviour is very disconcerting to a first time user of our device as it appears the device has shut itself off during power up.
Is there a way to configure the OS so the BIOS splash screen remains visible until the Application UI is displayed (i.e. eliminate the black screen)?
