A belated thanks for your help, Paul.
I've fixed the SM Bus Controller as per your instructions. Your remarks on the "Video Controller (VGA Compatible)" make perfect sense.
I've checked the "unknown device" in Device Manager but there's not much information on it. The General tab gives the location as "on PCI standard ISA bridge". The Details tab says that the Device Instance ID is "ACPI\ATK0110\1010110". Would any of the other fields in the Details tab give us sufficient information to determine what this thing is so that I can find the right drivers? If not, would it do any harm to simply remove the "unknown device" from the list in Device Manager? How would I remove the device from the list if that's what I want to do?

speed. It connects to things like the DIMMs, and allows the timing to be
read out. The interface should be part of the chipset, and use
"Chipset Drivers". The chipset driver package may have a list of what
devices are included in the package. I downloaded the chipset package,
and there are a lot of storage drivers, as well as the SMBUS you're
looking for. This is extracted from install.ini (and packages like
this may support more than one chipset).
"Unknown device" could be just about anything. In WinXP, you can do properties
on things like this, and there may be enumeration information.
As a cheat, features like "overclock controller" are passed as ACPI objects.
The driver comes with an Asus proprietary application, like say an
"Overclocking Application", which also installs a driver that connects
to the object. I presume this is the preferred method of gaining
hardware access with a non-administrator account. Looking in the manual
for M3A, I see "AI Gear 2", as the most likely solution to your
"unknown". If you install and then uninstall AI Gear 2, there is
a chance the "unknown" will be gone for good. You can decide
for yourself, whether stuff like that has a place on your
computer (if I overclock, it is always via BIOS controls).
VGA is coming from your video card. I don't see a GPU inside
your ATI 770 Northbridge, so I have to assume that is coming
from your new video card. Your new video card needs a driver,
but after you've installed the chipset stuff. Some chipset
packages are needed, to get system resources properly labeled.
Your video card may also insist on a certain minimum version
of DirectX, which will be included on the video card CD.
Try to install "AI Gear 2" then promptly uninstall it. The
unknown device, as near as I can tell, should be resolved
once AI Gear 2 is installed. On removal, it is possible the
driver will be left there, and the unknown device will then
The ATK thing is an Asus identifier, which means it is
created as a means of passing something from the BIOS
to the OS. My guess is, that AI Gear 2 is what uses
that interface. The unknown device is not real hardware,
but a virtual device that Asus made and passed via
an ACPI table entry.
