-//
-// Legacy16InitializeYourself
-// Description: This is the first call to 16-bit code. It allows the
-// 16-bit to perform any internal initialization.
-// Input: ES:BX pointer to EFI_TO_COMPATIBILITY16_INIT_TABLE
-// Output:
-// Legacy16UpdateBbs
-// Description: The 16-bit code updates the BBS table for non-compliant
-// devices.
-// Input: ES:BX pointer to EFI_TO_COMPATIBILITY16_BOOT_TABLE
-// Output:
-// Legacy16PrepareToBoot
-// Description: This is the last call to 16-bit code where 0xE0000 -0xFFFFF
-// is read/write. 16-bit code does any final clean up.
-// Input: ES:BX pointer to EFI_TO_COMPATIBILITY16_BOOT_TABLE
-// Output:
-// Legacy16Boot
-// Description: Do INT19.
-// Input:
-// Output:
-// Legacy16RetrieveLastBootDevice
-// Description: Return the priority number of the device that booted.
-// Input:
-// Output: BX = priority number of the last attempted boot device.
-// Legacy16DispatchOprom
-// Description: Pass control to the specified OPROM. Allows the 16-bit
-// code to rehook INT 13,18 and/or 19 from non-BBS
-// compliant devices.
-// Input: ES:DI = Segment:Offset of PnPInstallationCheck
-// SI = OPROM segment. Offset assumed to be 3.
-// BH = PCI bus number.
-// BL = PCI device * 8 | PCI function.
-// Output: BX = Number of BBS non-compliant drives detected. Return
-// zero for BBS compliant devices.
-// Legacy16GetTableAddress
-// Description: Allocate an area in the 0xE0000-0xFFFFF region.
-// Input: BX = Allocation region.
-// 0x0 = Any region
-// Bit 0 = 0xF0000 region
-// Bit 1 = 0xE0000 region
-// Multiple bits can be set.
-// CX = Length in bytes requested
-// DX = Required address alignment
-// Bit mapped. First non-zero bit from right to left is
-// alignment.
-// Output: DS:BX is assigned region.
-// AX = EFI_OUT_OF_RESOURCES if request cannot be granted.
-// Legacy16SetKeyboardLeds
-// Description: Perform any special action when keyboard LEDS change.
-// Other code performs the LED change and updates standard
-// BDA locations. This is for non-standard operations.
-// Input: CL = LED status. 1 = set.
-// Bit 0 = Scroll lock
-// Bit 1 = Num lock
-// Bit 2 = Caps lock
-// Output:
-// Legacy16InstallPciHandler
-// Description: Provides 16-bit code a hook to establish an interrupt
-// handler for any PCI device requiring a PCI interrupt
-// but having no OPROM. This is called before interrupt
-// is assigned. 8259 will be disabled(even if sharded)
-// and PCI Interrupt Line unprogrammed. Other code will
-// program 8259 and PCI Interrupt Line.
-// Input: ES:BX Pointer to EFI_LEGACY_INSTALL_PCI_HANDLER strcture
-// Output:
