Let me know if you can't find a good virus free download. My file is called "Asus G73jh Notebook.zip" and is 173,957,026 bytes. MD5 checksum is 72fe2920a9d126a0f4299888327c04ca
It contains all of the vBios's including the OD2, and the auxillary files needed.
Then test your current Catalyst, it may work with this vBios.
