like i said above--this is a kind of crippled image.  if you know what
you need to do you're fine, but it lacks even the 'copy con' ability
to print a text file, much less run rename (ren).

my bios update was a batch file that literally renamed a .sys file to
a .exe and ran it with some flags, but the 'ren' command wasn't found
and i couldn't read the batch file on the machine to figure out what
went wrong...

while there are other freedos images that have more commands, i could
not find one larger than 2.44MByte that i could modify usefully.  i
was probably just doing it wrong, but after a few rounds of unetbootin
and downloading i decided to just ask the lazyweb and found someone
who could help.  (actually lots of someones, but all of the other
instructions i could find needed legacy grub that i was unwilling to
install, since it wanted to remove the new grub to do so!)
