Hi My drive is cd-burner asus 1610A (16x10x40x), revision 1.20. It has 2mb of memory. Additional Info about it is on following page: http://www.asus.com.tw/optical/crw-1610a/specification.htm Asus claims about its models with A (such as 1610A) that they are created by ASUS, on inet i found note about acer. Drive is connected to intel'bx controller (my board is abit be6-ii). Jan
