All very 20 th Century.

On some HP towers, as well as on a much lesser known Supox mainboard, 
all I had to do was put the relevant firmware binary in the root 
directory of a FAT32 USB stick, plug in the stick and press a 
(specified) Function key during power up.  A routine in the firmware, 
then runs the upgrade.
