Thank you for your interest.
My laptop is a Clevo W76TUN.
It is sold by Novatech. The Novatech stock number is nnb-801
I tried a new installation of Ubuntu 12.04 with the "latest" BIOS that I was given by Novatech. I got the same error message. I tried to write it down while it was still on the screen:
Something like that.
Piix4=Smbus 7.0 SmBus base address uninitialised. Update BIOS
Despite the error, the installation went ahead OK. It is not nice to get an error message during installation though.
I would deeply love to get the latest BIOS from Phoenix, just to satisfy the itch, but there is no way I am paying $30.00 for it.
