CLX64L	Platform SMBIOS String Table Definition
This	table defines how SMBIOS string fields are mapped to HII string IDs
for	the CLX64L platform. Each entry is a 10-byte record:
Bytes	0-1: HII StringId (UINT16)
Byte	2: Field type encoding
Byte	3: SMBIOS structure sub-type
Bytes	4-5: Reserved (field size/offset info)
Bytes	6-9: Reserved
A	total of 22 entries are defined covering memory, cache, port, slot
onboard	device, OEM, and system information SMBIOS types.
Memory	Device - Type 17 fields
Physical	Memory Array - Type 16 fields
Cache	- Type 7 fields
Port	Connector - Type 8 fields
System	Slots - Type 9 fields
Onboard	Device - Type 10 (or extended) fields
OEM	Strings - Type 11 fields
System	Information - Type 1 fields
CLX64L	Platform SMBIOS Data Table Definition
This	table defines the SMBIOS data update entries for SMBIOS types
layout	of platform-specific binary data to be installed.
The	table is indexed by the SMBIOS type groups and contains raw
SMBIOS	structure data with embedded string references.
Type	0 - BIOS Information
Type	1 - System Information
Type	2 - Baseboard Information
Type	3 - System Enclosure
Type	4 - Processor Information
Type	7 - Cache Information
Type	8 - Port Connector Information
Type	9 - System Slots
CLX64L	Platform SMBIOS Memory Data Table Definition
This	table defines the SMBIOS data update entries for memory-related
SMBIOS	types (Type 11, 17, 19, 20). These provide OEM-specific
memory	configuration data and memory device mapping.
Type	11 - OEM Strings (memory-specific)
Type	17 - Memory Device
Type	19 - Memory Array Mapped Address
Type	20 - Memory Device Mapped Address
Initialize	SMBIOS string structure header:
Then	populate the structure from the string table entry fields
and	retrieve the actual string data from the HII database.
Structure	header (3 bytes)

Unused	handle
Map	string table entry fields into the output buffer.
Retrieve	the SMBIOS string from the HII database for all
configured	languages and format it into the string pack buffer.
return	EFI_SUCCESS;
Copy	the platform SMBIOS data template for the specified
data	table group into the output buffer. Each data table
group	contains a complete SMBIOS structure including:
For	CLX64L, the data table groups are:
Build	the appropriate memory SMBIOS structure:
Retrieve	the string from the HII database via the HII String protocol.
First	query the required buffer size, then allocate and retrieve.
StringSize	= 0;
Calculate	total string data size by iterating through the package list.
Each	package entry consists of:
PackageArray	= (UINT8 )PackageList;**
Calculate	string data size: total package size minus 4-byte header
StringDataSize	*= (UINT32* )PackageArray[Index] - 4;**
Allocate	the string pack buffer (24-byte header + string data)
StringPackBuffer	*= (UINT8 )AllocateZeroPool (TotalSize + 24);**
Initialize	the string pack header:
CopyGuid	*((EFI_GUID )StringPackBuffer, PackageGuid);**
Copy	string data into the pack buffer, starting at offset 20
UINT8	*DestPtr = StringPackBuffer + 20;
Append	the terminating 4-byte entry
Register	the string pack with HII database
Status	= gHiiDatabaseProtocol->NewPackageList (
Not	associated with a driver handle
If	no strings to update, return success
if	(NumStrings == 0) {
Build	the string pack by retrieving all strings sequentially.
Each	string is null-terminated and concatenated into the output buffer.
The	buffer format is compatible with SMBIOS string table expectations.
Retrieve	each SMBIOS string from the HII database
RetrievedString	= GetSmbiosString (
Grow	the buffer as needed
StringBuffer	*= (CHAR8 )AllocateZeroPool (TotalBufferSize + StringLen);**
Copy	the string data
if	(CurrentOffset > 0) {
Verify	the total string size does not exceed the maximum
supported	by the SMBIOS string table format
if	(TotalBufferSize > SMBIOS_STRING_PACK_BUFFER_SIZE) {
Allocate	a working buffer for string pack construction.
The	buffer must be large enough to hold the largest SMBIOS
string	table entry (768 bytes).
WorkBuffer	*= (UINT8 )AllocateZeroPool (SMBIOS_STRING_PACK_BUFFER_SIZE);**
Phase	1: Install SMBIOS String Table Entries
Iterate	through all 30 (0x1E) string table entries and install
each	one by formatting the SMBIOS structure and adding string
references	from the HII database.
for	(Index = 0; Index < SMBIOS_MAX_STRING_ENTRIES; Index++) {
The	formatted string table entry is ready for installation.
Write	it to the SMBIOS table via the string pack mechanism.
UpdateSmbiosStringPack	(
Phase	2: Install SMBIOS Data Table Entries
Install	Type 0-9 data tables for the CLX64L platform.
for	(Index = 0; Index < SMBIOS_MAX_DATA_ENTRIES; Index++) {
Phase	3: Install SMBIOS Memory Data Table Entries
Install	Type 11, 17, 19, 20 memory data tables.
for	(Index = 0; Index < SMBIOS_MAX_MEMORY_ENTRIES; Index++) {
This	is accomplished by sending an end marker via the string
protocol	to terminate the SMBIOS string pack.
