Code:

type ModuleRecord is 							
	record	
		GTag : std_logic_vector(7 downto 0);		
		Version : std_logic_vector(7 downto 0);	
		Clock : std_logic_vector(7 downto 0);
		NumInstances : std_logic_vector(7 downto 0);
		BaseAddr : std_logic_vector(15 downto 0);
		NumRegisters : std_logic_vector(7 downto 0);
		Strides : std_logic_vector(7 downto 0);
		MultRegs : std_logic_vector(31 downto 0);
	end record; 

Note that normally the only thing you would change is the "NumInstances" field
( 09h in your example )

The constants come from the IDROMConst.vhd file
