Good points. I must admit that I have not contacted Gigabyte as my experience with such large companies tells me that I will only get elevated blood pressure and absolutely no usable answer.

My main concern is not if the BIOS is secure, I'm very sure it's full of security vulnerabilities like most other software I use, but I have decided to trust Gigabyte like I have decided to trust the developers who build the Linux distro I'm using in that they are not malicious and trying to steal my information. The packages in my Linux distro are signed, so I can verify that they have not been modified since they left the developers machine, but I can't do the same thing with the BIOS update and that's what makes me uncomfortable.
