‘PCI Device’ driver needed – but which? (SP2)

Topic

New Reply

On the Dell Optiplex 320 XP Pro PC with which I have had all the trouble recently, I have managed to resolve all the problems to do with network printing by reinstalling Windows (twice), and then applying device drivers for the on-board NIC, the on-board Graphics, and something called SM Bus. However, I am still left in Device Manager with a big yellow question-mark for something called “PCI Device”. The appropriate driver cannot be found by searching any of C:DellDrivers, C:DellI386, the Dell System Recovery CD, the Dell Drivers CD, an OEM XP Pro CD, and the XP Pro SP2 CD.

I cannot see anything relevant in Dell’s Drivers and Downloads. Has anyone any clues about how to find out which driver(s) is/are needed?

Thanks!

A couple of things:

1] Several threads I came across, although not directly applicable, point to making sure you have the chipset/motherboard drivers loaded after a re-install. (See e.g. http://hardware.mcse.ms/archive14-2005-7-213232.html%5B/url%5D)

2] I also came across this aptly named freeware: Unknown Devices which will allegedly ” Find out what those unknown devices in Device Manager really are”.

If Leif’s freebie doesn’t do the trick, I wonder about SIW which I think you have already in your toolkit. I’ve never run SIW when something is missing or amiss, so I wonder, under Software what the “Drivers” selection will show. Also, under Hardware, there’s “Devices” and “PCI” that might show something missing.

Well, good that you found the drivers for the SM Bus; on an old system I had it sometimes popped up in the DM, and no searching on mobo CD’s etc. did help.

Anyhow, as you probably already have guessed a “PCI Device” can be anything; sound, SATA controller to mention some. The NIC and graphics are not reported as “PCI Device” by DM (Ethernet & Video Controller) so that gives fewer alternatives left. Since it is a “branded” PC, I’m a bit surprised that you found the NIC and SM Bus, but not this unknown PCI Device’s driver on the CD.

If you, in Device Manager, take a look at the Properties of this unknown device, and select the Details tab, look at the Device Instance ID (the details tab is enabled by default in XP SP2 and 2003 SP1).

The ID contains a string that is used when reporting hardware and locating the correct driver for the device.

You could try to locate the vendor and device number in that string and do a search on the net. A search at http://www.pcidatabase.com[/url%5D might give you some help. Though, it lists what people have reported so it can be wrong. There are probably other databases to search on the net.

Ex. graphic card
PCIVEN_10DE&DEV_01D1&SUBSYS_ etc.
Vendor 10DE = Nvidia, OK.
VIA IDE Controller
PCIVEN_1106&DEV_0571&SUBSYS_ etc.
1106 identifies VIA, but 0571 is reported as sound card, obviously wrong in my case.

Things like Windows Help and MS System information will probably report unknown device, so no help there.

Thanks, folks, the string is almost unintelligible but VEN_1002 seems to be ATI (even though I’ve installed the drivers for that video chipset…)

I will pursue more tomorrow…

Shucks, ya didn’t try Leif’s little freebie? I’m dying to see how that one would work and I don’t have a “live” situation to check it with. Both of my machines are up to snuff in device manager.

I just had a ‘minor’ problem where somebody sent out several hundred 5.4 MB emails, thereby rendering our Exchange server hors de combat for about 4

A quick FYI…

I thought I’d give it a try. You download a zip file which gives you an exe, and it is this you run to use it – no ‘installation’. It successfully identified an errant and surplus network card on one of our W2K servers, and with a ‘copy to Google’ facility allowed me to find the driver in no time. (I did need to trim the search term a bit first!)

So, full marks from me for a basic test. More info and a review is available here at Softpedia.

I ran the Unknown (PCI) Device program as suggested by Leif, and got some good results!

And your conclusion is?

When you said vendor 1002, you didn’t mention the whole device ID, or the device number, so there wasn’t much to go by. From your picture the little program mentions: Unknown Device and Unknown Chipset, albeit from ATI or Dell, not much help, or?

The first; Vendor 1002 Device 4383, could be sound (“audio”), IXP SB600 High Definition Audio Controller.
The second; Vendor 1002 Device 438D, could be ISA bridge: IXP SB600 PCI to LPC Bridge.

LPC bus is an Intel replacement for the ISA bus.

SB600, could that be SouthBridge that I mentioned? Hmm, yep, it seems so: ATI SB600 Series

The chipset in the Optiplex 320 is ATI Radeon

I can now report that I ran the extremely-unlikely-looking audio drivers file from Dell’s Drivers and Downloads, and it has removed the yellow question mark from Device Manager! (I didn’t imagine I had a Analog Devices ADI 198x Integrated HD Audio…). Thanks to all contributors for their help!

I would guess from what I find that this PC has an ATI Radeon Xpress 1100 Pro. chipset, and an, as you mentioned integrated graphics, Integrated ATI Radeon X300 Graphics (128MB ATI Radeon X1300 is aparently an option).

Thus, you have ATI there for more than just graphics.

But a quick look at the Dell support (I went trough a little modell search/support click-around, to get to the same page you linked in your first post (albeit in US)), and looked at chipset drivers.

What I thought was, IF your device vendor is true, it could be some IDE controller etc. But since you have fixed the SM Bus driver you maybe fixed that other too.

“This combo release contains SMBus INF (version 5.10.1000.6) as well as ATI mini-IDE driver (version 1.00.0000.0).”

In that driver they combined two drivers it seems.

Ah, probably was tired on typing, and stopped thinking; should do the opposite; first stop typing, then stop thinking.

The IDE/SATA controller would probably be reported by DM as “System Interrupt Controller” and a question mark, not a “PCI Device”. Your NIC was probably reported as a Ethernet Controller, graphics maybe as Video Controller.

On my latest hardware I also have another SATA Controller chip, and that one was reported as PCI Device. (Then I had an odd one, the ACPI, only had to put the mobo CD in and autorun to install. Obviously something one may miss if one download drivers separately, but that one is reported as “unknown device”, not PCI Device.).

It could be sound (but then you found ATI, so not), SATA, southbridge …, we’ll see.
