Here is the beginning of the CrScreenshotDxe project. It is from the year 2016. According to the instructions, LCtrl + LAlt + F12 is the keyboard shortcut handler although I already told you that my Apple Keyboard works with F10.

As you can read, the project was looking for a way to take screenshots of the UEFI BIOS screens using the feature of adding DXE drivers into BIOS images with UEFITool.

But, as you surely know, many modern BIOSes have this feature built in. We must boot the PC with a USB flash drive (formatted as FAT or FAT32) previously connected and press F12 or Print Screen when we are in the chosen BIOS screen. If the screenshot is captured successfully, a confirmation message should appear immediately. The image is saved to the USB stick in BMP format.
