Then I changed it to USB HDD and it brought up a page indicating windows did not boot up successfully.

I want to update the BIOS on my two servers with Supermicro boards (X10SRH-cF and X10SL7-F). I've downloaded the 3.0a BIOS for each of these boards, and if I understand the directions correctly, I 'simply' need to copy the contents of the expanded zip files onto a bootable USB stick. Do I need to add an OS such as FreeDOS, or are the contents of the BIOS zip from Supermicro all I need? How would I create a bootable USB stick using macOS 10.13? All the info I've found so far assumes you want to use an ISO to make a bootable USB stick, so they point to tools like UNetbootin. I've tried using diskutil partitionDisk /dev/disk3 MBR MS-DOS X10SL7F 0b at the CLI in macOS, but Disk Utility says the resulting USB stick is not bootable. How large a USB stick do I need? I've got some ancient 64MB ones that I'd like to use for this, if possible. That is way more than the size of the expanded BIOS zip archives. I'm sure the info I need is buried in this forum somewhere, but my Google-fu isn't strong enough to find it. Thanks for any pointers.
