  Adds a record into S3 boot script table.
 | 
						|
 | 
						|
  This function is used to store a boot script record into a given boot
 | 
						|
  script table. If the table specified by TableName is nonexistent in the 
 | 
						|
  system, a new table will automatically be created and then the script record 
 | 
						|
  will be added into the new table. This function is responsible for allocating 
 | 
						|
  necessary memory for the script.
 | 
						|
 | 
						|
  This function has a variable parameter list. The exact parameter list depends on 
 | 
						|
  the OpCode that is passed into the function. If an unsupported OpCode or illegal 
 | 
						|
  parameter list is passed in, this function returns EFI_INVALID_PARAMETER.
 | 
						|
  If there are not enough resources available for storing more scripts, this function returns
 | 
						|
  EFI_OUT_OF_RESOURCES.

                                specified script table.
