As I mentioned on my previous post about high CPU usage by audiodg.exe, I highly suspected that the culprit is because I upgrade my ASUS Notebook BIOS. So, here I’ll show you how to downgrade your Asus Notebook BIOS.
Asus Notebook has two way of upgrading/downgrading your BIOS. One way is using EasyFlash via BIOS boot screen and another way is using WinFlash utility. I’ll use WinFlash in this tips. Why? Because I can’t take BIOS boot menu screenshot
WinFlash can be found on your Notebook CD driver companion or from Notebook Asus driver download page.
Normally, WinFlash would not let you downgrade your BIOS. You’ll get warning and can’t click on “Flash” button. So, we need “unusual” way to start WinFlash utility
There you have successfully downgraded your Asus Notebook BIOS!
Tested on: Windows 7 64bit, Notebook Asus A43SV, BIOS Revision 317 downgrading to Revision 314
