DXE drivers that require read-only access or read/write access to volatile environment variables must have EFI_VARIABLE_ARCH_PROTOCOL in their dependency expressions. DXE drivers that require write access to nonvolatile environment variables must have the EFI_VARIABLE_WRITE_ARCH_PROTOCOL in their dependency expressions.  · Solved by writing driver that suggest to run an app. Idea to create event and catching EVT_SIGNAL_EXIT_BOOT_SERVICES wouldn't work because after this [actually after ExitBootServices()] event several fields of the EFI System Table should be set to NULL. 0x03 = PEI Driver 0x04 = DXE Core 0x05 = DXE Boot Driver 0x06 = DXE Runtime Driver 0x07 = SMM Driver 0x08 = EFI Application 0x09 = OS Loader 0x0C = EBC Exception 0x0D = X86 Exception 0x0F = PEI Service 0x10 = UEFI Boot Service 0x11 .

Use cmd ' bcfg driver add 0 fs1:\EFI\Boot\www.doorway.ru "V3 Full Turbo" ' where 'fs1:\EFI\Boot\www.doorway.ru' is path to DXE driver file on UEFI boot partition (use cmd 'mountvol x: /s' to mount in Windows as drive X: for writing) {Note: there is a bug which prevents accessing the mounted drive through File Explorer in Windows 10 build The Extensible Firmware Interface (EFI) can be implemented in many ways. One way is to implement via the Driver Execution Environment (DXE) Foundation portion of the Framework. As such, DXE represents a special type of driver that can be combined with EFI drivers in a given firmware volume. The DXE Foundation is considered a boot service component, so the DXE Foundation is also released when ExitBootServices() is called. As a result, runtime drivers may not use any of the UEFI Boot Services, DXE Services, or services produced by boot service drivers after ExitBootServices() is called.
