Bios chip location on asus mother board

It's next to the red sata ports. You will need a special tool called a PCLL puller, available at some online venders for about $10. Asus will mail you a new bios chip if they have any left for your board for about $15-20 shipped, depending on which part of the world you live in.

You can also get a BIOS chip from here http://www.biosman.com/

May be a little more money, but very fast service.
