- This function uses policy data from the platform to determine what operating

- also optionally make the use of user input to determine the operating system
- or system utility to be loaded and invoked. When the DXE Core has dispatched
- all the drivers on the dispatch queue, this function is called. This
- function will attempt to connect the boot devices required to load and invoke
- the selected operating system or system utility. During this process,
- additional firmware volumes may be discovered that may contain addition DXE
- drivers that can be dispatched by the DXE Core. If a boot device cannot be
- fully connected, this function calls the DXE Service Dispatch() to allow the
- DXE drivers from any newly discovered firmware volumes to be dispatched.
- Then the boot device connection can be attempted again. If the same boot
- device connection operation fails twice in a row, then that boot device has
- failed, and should be skipped. This function should never return.

- passed the amount of time that has passed since the previous timer
- interrupt.
-
- @param RegisterHandler
- Registers a handler that will be called each time the
- timer interrupt fires. TimerPeriod defines the minimum
- time between timer interrupts, so TimerPeriod will also
- be the minimum time between calls to the registered
- handler.
-
- @param SetTimerPeriod
- Sets the period of the timer interrupt in 100 nS units.
- This function is optional, and may return EFI_UNSUPPORTED.
- If this function is supported, then the timer period will
- be rounded up to the nearest supported timer period.

- Retrieves the period of the timer interrupt in 100 nS units.
-
- @param GenerateSoftInterrupt
- Generates a soft timer interrupt that simulates the firing of
