Today i updated my asus maximus iv extreme from bios version 1303 to version 3604 with the ez flash 2 tool. the update was succesfull, but after the restart windows won't boot, because of an inaccessible device.. Long story short it won’t boot and when starting computer it only displays the asus bios utility.i cannot restore bios to original using f5. and went to advance mode/tool/asus ez flash 2 utility and clicked on it. what i see is this-flash 2 utility. it ran the utility three times and now when i start it all i get is my monitor saying. This quick tutorial shows how to flash your firmware (update bios) using any modern asus board. we used an asus crosshair v in this guide, but the steps apply to any other e-z flash-equipped board..
Reboot. when the system is at post, press "alt" + "f2" to enter ez-flash. alternatively, on late model motherboards you may press "delete" to enter bios setup, then access ez-flash from the "tools" option on the navigation bar. (select tools > asus ez flash 2 > yes). Geforce
