EFI_ACPI_DESCRIPTION_HEADER EFI_ACPI_6_4_BOOT_GRAPHICS_RESOURCE_TABLE::Header |
UINT64 EFI_ACPI_6_4_BOOT_GRAPHICS_RESOURCE_TABLE::ImageAddress |
8-byte (64 bit) physical address pointing to the firmware's in-memory copy of the image bitmap.
UINT32 EFI_ACPI_6_4_BOOT_GRAPHICS_RESOURCE_TABLE::ImageOffsetX |
A 4-byte (32-bit) unsigned long describing the display X-offset of the boot image. (X, Y) display offset of the top left corner of the boot image. The top left corner of the display is at offset (0, 0).
UINT32 EFI_ACPI_6_4_BOOT_GRAPHICS_RESOURCE_TABLE::ImageOffsetY |

UINT8 EFI_ACPI_6_4_BOOT_GRAPHICS_RESOURCE_TABLE::ImageType |
1-byte enumerated type field indicating format of the image. 0 = Bitmap 1 - 255 Reserved (for future use)
UINT8 EFI_ACPI_6_4_BOOT_GRAPHICS_RESOURCE_TABLE::Status |
1-byte status field indicating current status about the table. Bits[7:3] = Reserved (must be zero) Bits[2:1] = Orientation Offset. These bits describe the clockwise degree offset from the image's default orientation. [00] = 0, no offset [01] = 90 [10] = 180 [11] = 270 Bit [0] = Displayed. A one indicates the boot image graphic is displayed.
