|
|
All future revisions will be backward compatible to the current revision.
|
|
|
|
@param ParentHandle

|
|
the firmware's boot manager.
|
|
|
|
@param SystemTable
|
|
The image's EFI system table pointer.
|

|
|
@param DeviceHandle
|
|
The device handle that the EFI Image was loaded from.
|
|
|
|
@param FilePath
|
|
A pointer to the file path portion specific to DeviceHandle
|
|
that the EFI Image was loaded from.
|
|

|
|
@param LoadOptionsSize
|
|
The size in bytes of LoadOptions.
|
|
|
|
@param LoadOptions
|
|
A pointer to the image's binary load options.
|
|
|
|
@param ImageBase
|
|
The base address at which the image was loaded.
|
|
|
|
@param ImageSize
|
|
The size in bytes of the loaded image.
|
|
|
|
@param ImageCodeType
|
|
The memory
|
|
|
|
@param ImageDataType
|
|
