I am working on an eMachine T5062 which originally had 32 bit Vista
installed on it. The owner wants XP and provided a new XP Pro CD to install
it with. I checked on the eMachine (Gateway) site and found that they had
the XP drivers for video and audio listed so I went ahead and did the
install. I had to use those downloaded drivers which worked fine for the
audio & video. Also not installed were the SB Bus Controller, LAN and modem
devices. I installed a temporary wireless adapter to access the internet
and then the Hardware Wizard located the drivers for the LAN and modem.
That leaves only the SM Bus Controller which I have spent half the night
trying to find a driver for. The processor is an AMD Athlon 3800+. The SM
Bus Controller is showing up under Other Devices with a yellow question
mark. I spent close to a half hour in chat with a gateway/eMachine tech and
he couldn't come up with a fix, but agreed that that model supports XP
since they provided audio and video drivers for it. Supposedly an elevated
support person will be calling me Monday but I got the feeling from the way
he talked it's going to be a fee based call.
Does anyone have any ideas on this?
Incidentally, everything seems to be working just fine *without* the
controller. I'm not even sure what it is supposed to do!
Google hasn't been my friend. I've downloaded about 5 different files that
were supposed to fix it, but none of them would even install.

You need chipset drivers, for an Nvidia 6150SE. That's the info I got here.
There are tools like Everest and Belarc Advisor, that might tell you things
like that, but I don't really like any of the tools, in terms of there
thoroughness. In this case, I can at least get some info on the chipset,
but I don't know exactly what other peripheral chips might be present.
SMBus is a slow serial bus, that originates on the Southbridge. It
connects to the DIMMs, and the DIMM timing tables are read out using
that bus, by the BIOS. Perhaps CPUZ wouldn't run properly with that
driver missing ? Or maybe Speedfan would have problems ?
The SMBus can also be used to host temperature sensors, but on modern
machines, much of that will have moved to LPC bus. At one time, there
was even an SMBus header on the motherboard, so you could connect
"toys" to the SMBus. The Asus iPanel might have been an example of that.
Now, the trick will be finding a driver. I happened to track down one
similar to this recently, so this wasn't too hard to find.
nForce 4 Series
nForce 430 / GeForce 6150SE
nForce Driver 15.26, 2009.03.16, 162MB
Windows XP 32-bit Driver Versions:
* Ethernet Driver (v67.89) WHQL
* Network Management Tools (v67.96) "Sedona"
* SATAIDE Driver (v10.3.0.46) WHQL
* SATARAID Driver (v10.3.0.46) WHQL
* RAIDTOOL Application (v10.3.0.46)
* SMU Driver (v1.61) WHQL
* SMBus Driver (v4.69) WHQL <---------
* Away Mode Driver (v6.0.6000.107) WHQL
* Installer (v6.69)
As far as I know, the installer will offer tick boxes, and
you'd just tick the SMBus one and not bother installing
the rest of it. If the motherboard design uses the
built in Ethernet, then the Ethernet MAC layer will be
in the Southbridge, and a separate PHY chip outside completes
the Ethernet implementation. You'd tick the box next to the
Ethernet Driver (v67.89) WHQL entry, if you needed that one.
If the motherboard designer uses a completely separate Ethernet
chip (like a RealTek), then you'd be off to a separate
web site to get a driver. You said you already got the Ethernet
running, so probably nothing to worry about there. Some of the
other driver choices, would be a function of the disk operating
mode. As for the "SMU" one, not a clue :-) I'd have to look that
