    please guide me how to revert it to 805

    Looking at the specs for the board...looks like your correct...don't see it either....not to worry....download and extract bios 805 to a USB...make sure drive is FAT32 formatted....rename the bios file as a cap file ...then boot back into the bios EZ 3 update utility....and choose storage as method to update....pick the drive that the bios is stored on and look for the bios file that has been renamed .... as a .CAP....you should get the message to read the file...pick yes...then it should update

    Like I said previously, you have to use the bios flashback feature to revert to an older bios.

    If the board doesn't have bios flashback, it can't be done.

    Thanks NemesisChild...saw that OP never had FB option on board...figured it was worth a shot to try as a last ditch effort to help OP

    You say bios 805 yet the old bios 18/06/08 is actually '0805'.

    You should have updated to 0805 before updating to 1002 because 0805 has the 'new' MEI update.

    There is no bios flashback feature on this board. So you are right back to clearing the cmos if you want anything to change.

    The OP can possibly downgrade the bios within Windows using the CMD prompt and either Easy Flash or WinFlash....however ...do so at your own risk.
