Read	CMOS index 0x4B to get debug level
DebugLevel	= IoRead8 (0x70);
OemSaveSmbiosPcdvalue	-- sub_41C
Reads	all system/board/chassis PCD values and saves them into the
OemSmbiosPcdValue	UEFI variable.
System	information buffers (280 bytes each for SMBIOS strings)
CHAR8	SmbiosStrings[13][280];
Read	existing variable (may not exist on first boot)

Token	188 - Chassis Type: if already 2, skip; otherwise restore from saved byte
OemRestoreSmbiosString	-- sub_1138
Applies	restored PCD values into the SMBIOS table via EFI_SMBIOS_PROTOCOL.
For	each type (1=System, 2=BaseBoard, 3=Chassis), if the corresponding
restore	flag is set, writes the string into the SMBIOS record.

OemSaveSmbiosDxeEntryPoint	-- _ModuleEntryPoint
Driver	entry point. Initializes globals, then calls the three main
routines	in order: OemRestoreSmbiosPcdvalue, OemSaveSmbiosPcdvalue
Initialize	HOB list
GetHobList	();
Standard	UEFI DXE driver entry.
