This DXE driver tries to register keyboard shortcut (LCtrl + LAlt + F12) handler for all text input devices.
The handler tries to find a writable FS, enumerates all GOP-capable video devices, takes screenshots from them and saves the result as PNG files on that writable FS.
The main goal is to be able to make BIOS Setup screenshots for systems without serial console redirection support, but it can also be used to take screenshot from UEFI shell, UEFI apps and UEFI bootloaders.
To start the driver, you can either:
It’s a normal EDK2-compatible DXE driver, just add it to your package’s DSC file to include in the build process.
Load the driver, insert FAT32-formatted USB drive and press LCtrl + LAlt + F12 to take screenshots from all GOP-compatible graphic consoles available at the moment.
To indicate it’s status, the driver shows a small colored rectangle in top-left corner of the screen for half a second.
