I did not mean to imply that Win98SE was definitely required, just that
I used it in the attempt that ultimately was successful.  I likely had
this problem solved a few times without realizing it, since I made
numerous bootable freedos usb sticks.  They did not work in my bios
upgrade attempts, but they may very well have worked if I had correctly
guessed the right steps.   I have not seen a DOS prompt in several years
and I was worried about the boot menu because I expected the bios update
to be unable to handle dealing with a menu.  I was looking for a boot
straight into the C: prompt, then I realized the A: prompt was more
likely, and then realized the C: prompt would be the usb file system
root.  Then I decided just to try running the .exe file before buying a
new mobo.  In the documents you found there are two files discussed, one
of which is a bios.bin, which probably would have worked.  That was not
the case with the MSI download for my situation -- everything was
contained in the .exe file.

My personal opinion is that after repeatedly warning that a bios upgrade
can ruin your computer, there should be some effort to have directions
that match the process, but that is just me.  The whole thing was a
learning experience, which I may never use again.

It may be of interest to the FreeDOS community that the "M-Flash"
process required a UEFI boot setup on the DOS usb stick, which seems to
be a bit incongruous  (not if UEFI is really about selling more
product).  However, it was happy to use my non-uefi stick when it found
a bios.bin file, which was the old bios I backed up onto the usb stick. 
Directly running the .exe file did the upgrade, but you would not have
known that from the bios screen or any directions I found.
