As Jones says, EZflash2 and a usb stick work quite nicely on Asus boards. Always read the instructions in your manual and on the Asus site. The largest dangers of bios flashing are power interruptions, whether it be from the utility company or the user stopping the process part way, don't do that.
Don't forget that after flashing, you need to go into the bios and load setup defaults, then save and exit. On the reboot go into the bios again and make your usual adjustments.
