LiveUpdate runs on any OS the purchaser might install, or just Windows? I have never had to perform a BIOS update with any off the shelf computer from ASUS. I have looked at the BIOS updates on offer. I cannot recall that they were always hosted on a server using HTTPS. Or that MD5 signatures were provided. But my understanding was that only users that knew what they were doing applied BIOS updates after purchase. Is flashing the BIOS really common with ordinary users? It's a major change and not something I would want to be done automatically by a third party. This auto-updating craze is becoming a bit farcical. Running programs that let third parties open ports, and run downloaded executables. But the concern is whether someone can MITM or tamper with the download?
