Flashing MSI 945GZM6-F succeeded perfectly.
It helped me automatically installing 23 workstations using PXE,
while the previously installed BIOS had a bug in the PXE ROM.
No need to say how happy I am to save all these motherboard. They
are now in use for free by refugees. Obsolete systems for Windows,
great machines for Linux. Another miracle by the open source
community.
