After spending about 3 hours last night trying to figure out how to make bootable media in order to get this done, I reread the Read Me file. I guess I had skipped over the F7 BIOS option. All I had to do was enter the motherboard setup, go to Advanced>Boot configuration and enable Display F7 to Update BIOS. Then from the splash screen at startup, I just hit F7 to access my flash drive.
The only thing that confused me from there was that I only saw two options on-screen: 1) Refresh list of flash media and (2) Exit F7 BIOS Update. After a few minutes of confusion as to why my flash drive was not displayed, I pressed the up arrow so that nothing on the screen was selected. I pressed Enter and it opened my flash drive to show the .bio update file. All is good now.
Glad that all is good. I had trouble updating the BIOS via window method, but the flash drive method was a charm.
BTW, you don't need to enable the F7 to display, just hit F7 anyway and it will give you the flash drive.
