How to get the Asus CDRW 522452A Dos firmware to use with MTKflash or WinMtk?

where can i find the Bin file so i can update it ??

the asus site only has EXE file a Win Executble

and it doesn’t Boot Well, i dunno what is wrong, and my Yamaha 3200E 1.0d is almost same, slow and sometimes says there is problem with coping when installing winXP from boot

any ideas?
