+EFI_MM_SYSTEM_TABLE
+
+The Management Mode System TAble (MMST) is a table that contains a collection of common services for managing MMRAM allocation and providinh basic I/O services. These services are intended for both preboot and runtime usage.

+UINTNNumberOfTableEntries;
+EFI_CONFIGURATION_TABLE*SmmConfigurationTable;
+
+MmConfigurationTable
+A pointer to the UEFI Configuration Tables. The number of entries in the table is
+NumberOfTableEntries. Type EFI_CONFIGURATION_TABLE is defined in
+the UEFI Specification, section 4.6.

+System Table contains pointers to the active concole devices, a pointer to the Boot Services Table,
+a pointer to the Runtime Services Table, and a pointer to the list of system configuration tables such as
+ACPI, SMBIOS and the SAL System Table.
+
+Entry point is the same for UEFI applications and UEDI drivers.

+PROTOTYPE
+	typedef
+	EFI_STATUS
+	(EFIAPI *EFI_IMAGE_ENTRY_POINT) (
+	IN EFI_HANDLE	ImageHandle,
+	IN EFI_SYSTEM_TABLE *SystemTabel
+	);
+
+PARAMETERS
+	ImageHandle The firmware allocated handle for the UEFI image
+	SystemTable 	A pointer to the EFI System Table. Contains standard output and input handles,
+			plus pointers to the EFI_BOOT_SERVICES and EFI RUNTIME_SERVICES tables.
+			The service tables contain the entry points in the firmware for accessing the core EFI system
+			functionality. The handles in the system table are used to obtain basci access to the console.
+			In addition, the System Table contains pointers to other standard tables that a loaded image 
+			may use if the associated pointers are initialized to nonzero values.
+			Example of such tables: ACPI, SMBIOS, SAL System Table, ...
+
+
+
+If the UEFI image is a UEFI application that is not a UEFI OS loader, then the application executes and
+either returns or calls the EFI Boot Services EFI_BOOT_SERVICES.Exit(). A UEFI application is always
+unloaded from memory when it exits, and its return status is returned to the component that started the
+UEFI application.
+
+EFI_TABLE_HEADER
+Datastructure that precedes all of the standard EFI table types
+
+typedef struct {
+	UINT64 Signature;
+	UINT32 Revision;
+	UINT32 HeaderSize;
+	UINT32 CRC32;
+	UINT32 Reserved;
+	} EFI_TABLE_HEADER;
+
+
+EFI_SYSTEM_TABLE
+Except for the table header, all elements in the service tables are pointers to functions as defined
+in Section7 (Services - Boot Services) and Section8 (Services - Runtime Services).
+
+Prior to a call to EFI_BOOT_SERVICES.ExitBootServices(), all of the fields of the EFI System Table are valid.
+After an operating system has taken control of the platform with a call to ExitBootServices(), pmöy
+Hdr, FirmwareVendor, FirmwareRevision, RuntimeServices, NumberOfTableEntries, ConfigurationTable fields
+are valid.

+
+PARAMETERS
+	ConcoleHandle		The handle for the active console input device. This handle must support
+		EFI_SIMPLE_TEXT_INPUT_PROTOCOL and EFI_SIMPLE_TECT_INPUT_EX_PROTOCOL.
+	ConIn			A pointer to the EFI_SIMPLE_TEXT_INPUT_PROTOCOL interface that is
+				associated with ConsoleInHandle.
+	ConsoleOutHandle	The handle for the active console output device. This handle must
+				EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.
+	ConOut			A pointer to the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL interface that is
+				associated with ConsoleOutHandle.
+	StandardErrorHandle	The handle for the active standard error console device. Must support
+				EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.
+	StdErr			A pointer to the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL inte4rface that is
+				assiciated with StandardErrorHandle
+	RuntimeServices		A pointer to the EFI Runtime Services Table (Section 4.5)
+	BootServices		Section 4.4
+	NumberOfTableEntries	Number of system configuration tables in the buffer ConfigurationTable
+	ConfigurationTable	A pointer to the system configuration tables. Number of entries in the table is
+				NumberOfTableEntries.
+
+EFI Boot Services Table
+	contains a table header and pointers to all of the boot services. Except for the table header, all elements
+	in the EFI Boot Services Tables are prototypes of function pointers to functions as defined in Section 7.
+	The function pointers in this table are not valid after the operating system has taken control of the platform with a call to 	
+	EFI_BOOT_SERVICES.ExitBootServices().
