MISC_SMBIOS_TABLE_FUNCTION (
|
|
MiscPortInternalConnectorDesignator
|
|
)
|
|
/*++
|
|
Description:
|
|
|
|
This function makes boot time changes to the contents of the
|
|
MiscPortConnectorInformation (Type 8).
|
|
|
|
Parameters:
|
|
|
|
RecordType
|
|
Type of record to be processed from the Data Table.
|
|
mMiscSubclassDataTable[].RecordType
|
|
|
|
RecordLen
|
|
Size of static RecordData from the Data Table.
|
|
mMiscSubclassDataTable[].RecordLen
|
|
|
|
RecordData
|
|
Pointer to copy of RecordData from the Data Table. Changes made
|
|
to this copy will be written to the Data Hub but will not alter
|
|
the contents of the static Data Table.
|
|
|
|
LogRecordData
|
|
Set *LogRecordData to TRUE to log RecordData to Data Hub.
|
|
Set *LogRecordData to FALSE when there is no more data to log.
|
|
|
|
Returns:
|
|
|
|
EFI_SUCCESS
|
|
All parameters were valid and *RecordData and *LogRecordData have
|
|
been set.
|
|
|
|
EFI_UNSUPPORTED
|
|
Unexpected RecordType value.
|
|
|
|
EFI_INVALID_PARAMETER
|
|
One of the following parameter conditions was true:
|
|
RecordLen was zero.
|
|
RecordData was NULL.
|
|
LogRecordData was NULL.
