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