-Routine Description:
-
- This is the routine which an external caller uses to direct the browser
- where to obtain it's information.
-
-Arguments:
-
- UseDatabase - If set to TRUE, then all information is retrieved from the HII database handle specified
- If set to FALSE, then the passed in Packet and CallbackHandle is used and Handle is ignored
-
- Handle - A pointer to an array of Handles. If HandleCount > 1 we display a list of the formsets for the handles specified
-
- HandleCount - The number of Handles specified in Handle.
-
- Packet - Valid only if UseDatabase is FALSE. Packet defines the pages being passed into
- the browser. This is composed of IFR data as well as String information.
-
- CallbackHandle - The handle which contains the calling driver's EFI_FORM_CALLBACK_PROTOCOL interface.
-
- ScreenDimenions - This allows the browser to be called so that it occupies a portion of the physical screen instead of
- dynamically determining the screen dimensions.
-
- NvMapOverride - This buffer is used only when there is no NV variable to define the current settings and the caller
- needs to provide to the browser the current settings for the "fake" NV variable. If used, no saving
- of an NV variable will be possible. This parameter is also ignored if HandleCount > 1.
