I assume that was posted to prevent bricking the MB if the BIOS update fails. Under warranty the MB would be replaced as opposed to a charge outside of warranty. My opinion...if the system is working fine with no other reason to update the BIOS, then leave well enough alone. The forum is full of posts dealing with BIOS updates gone wrong. If you look at MB manufacturers such as MSI, ASUS, Gigabyte, etc., they post notices on their BIOS update pages stating if the MB is running fine then they do not recommend updating the BIOS.
Someone on this forum said that one should not install bios updates after the warranty has expired. I would like to hear what opinions others have, pro and con.
