Re-building WinXP - Mystery "PCI Device" and mystery "SM BusController"...

[ship]

Hi

I am rebuilding my Windows XP Pro (OEM).

When I check my Device Manager,
( Control Panel > System > Hardware > Device Manager )
...I find there are errors:
"? Other devices:
? PCI Device
? SM Bus Controller"
...with yellow ? marks.

The only card that I think I have in the box (judging by the outside)
is Matrox Millenium graphics card (see below)

Is it likely that it is causing the "PCI device" error??
Because it seems to be working fine (as far as I can see...)

Also can anyone tell me what a "SM Bus Controller" is and what
I should be downloading to fix that too?

Help!

With thanks

SM Bus controller driver should be part of the Chipset driver package
for your motherboard. The PCI device is likely a Modem or on-board
Sound Controller chip. If you enable DevMgr_Show_Details variable
you'll get a "Details" (TAB) when you open the properties of the device
in Device Manager. It will show you the Device_Instance ID that contains
a string of text that identifies the Vendor and Unique ID for the hardware.

And then use this very handy website to identify the exact device and
manufacturer. This is a super resource.

How is this done?

SM Bus controller driver should be part of the Chipset driver package

for your motherboard.

I downloaded something from Intel (Intel Chipset Device Software)
that seems to have removed the "SM Bus Controller" flag

If you enable DevMgr_Show_Details variable
you'll get a "Details" (TAB) when you open the properties of the device
in Device Manager.

Sorry to be dumb but how do I "enable DevMgr_Show_Details" ?
Is that something in the registry?

It's a System Environment Variable you add the name and
then set it's value = 1. System Properties, Advanced ( TAB),
Environment Variable button, button section for System level.
You may not need to do that just visit the Motherboard vendor site
and locate the drivers for your motherboard. All the built-in or on
board devices should have drivers posted there.

Okay - I've worked out how to set this.
(I think it was Control Panel > System > Advanced >Environmental
Variables > System Variables
And then I hit New, entered the variable and gave it a value of "1". )

So I now have a Device Instance ID of
"PCI\VEN_8086&DEV_27D8&SUBSYS_02028086&REV_01\3&61AAA01&0&D8"

Crikey. Now what?

Decoded it's an Intel based Microsoft UAA Bus HD Audio

Okay I'm guessing wildly, but I used that link from Colin to
http://www.pcidatabase.com/
and I reckon 8086 sounds like Intel. If so then my next guess is that
(using this URL
http://www.pcidatabase.com/vendor_details.php?id=1302 ) that the
device is 27D8
which comes up as:Chip Number: 29331019
Chip Description: Microsoft UAA Bus HD AudioNow I just need the driver.
But that is where the trail has gone cold...
I cant find anything on www.intel.com so far.

Okay on this page:
http://downloadcenter.intel.com/fil...XP+Professional&lang=eng&strOSs=44&submit=Go!

...I managed to get this driver to download and install:

"Audio: Sigmatel* (IDT*) 92XX Driver (19491KB)"
But it hasnt actually changed either the "?" against PCI.
Nor is there any Audio Device installed apparently.

So then I tried downloading: "Audio: Sigmatel* (IDT*) 92XX Audio
Drivers"
... and HURRAY - it works. We have sound folks.
And that ? has gone from Device Manager.

P.S. How come these things are still QUITE so hard?
