I read this:
If the Flash Memory Writer utility was not able to successfully update a complete BIOS file, your system may not be able to boot up. If this happens, your system will need service. SERVICE....1 day motherboard
Why would you want to update the BIOS on a one day old motherboard? Have you ever changed a BIOS chip? it is not that hard if you have the tool to do it with, a new BIOS chip from ASROCK should not be very much. I have changed 4 already, from people who have had a failed attempt with an update.
You could send the board to Asrock and have them install the latest BIOS that way you will not have to update it, just time and money. Contact Asrock see what they have to say. Right now your board is just a paper weight.
