You can't easily make a CD, but I'll make one for you. You know how to burn ISO image correct?
This is a ISO File, DO NOT EXTRACT if you think it's Zip or other format as it is not. If you are unsure how to burn a ISO image please google "how to burn ISO image"
http://www.mediafire.com/?9c9l8fs3vgj651gOnce you boot to this CD you will have to do the following:
Change drive path to Z after DOS Loads
type Z: at the A:> Prompt
Then dir/w shows the files on Z if you want to view them
Then type the following (At the Z: Prompt) to actually do the BIOS flash
flashspi X58AUD3R.FF
Again, please DO NOT extract the above linked file, it is NOT a Zip file.
