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

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.

This function closes the specified boot script table and returns the base address

table. Once this function is called, the specified table will be destroyed after it is
