Unknown device....but what??

December 14, 2005 at 12:51:58
Specs: Windows 98SE, 500/256

Just reinstalled Windows on a Tiny branded Windows 98SE system - motherboard is an Intel based MS6178 ver1.1. All drivers are installed except for one - an 'unknown PCI device'.

The system has integrated graphics & sound - both identified & working. Only card is an MR modem - again, installed & working, including the 'wave device'. There are no other cards, everything else on the system works ok but I still get this 'unknown device'.
Has anyone got any idea what this device might be or how I can either identify or eliminate it?

Not knowing what connections you have brought out, could it be a USB(s) or IR port? Network card?

Some times windows will give an "unknown" to the system, that is the motherboard.
Some times called the PCI bus. But it also can be something like a Network card.

You can remove the "unknown" from the Device manager shut down. Then pull the Modem out restaret and see if windows still finds the unknown. If it does then I would look for a Driver for the PCI Bus. Look in device manager under system for a pci bus

I think I've gotten that error when some of the audio items weren't installed. May have been the gameport.

It could also be associated with the modem. You can just physically remove the modem card to check that. If on next boot up the 'unknown' message is gone, then it was the modem.

Thanks for all responses. There's no network or IR facility on the board; the usb ports are identified & listed; the 'unknown device was already listed before I applied drivers for the sound & modem & have gameport & legacy audio drivers listed. I couldn't find specific motherboard drivers & didn't fancy possibly installing incorrect ones so this may be the cause. Thanks again for ideas.

Try installing the chipset drivers.

Aah, that's the slight problem - the system is a 'Tiny' branded and the mobo model number is labelled as MS6178v1.1 - I've gone through the MSI downloads but I cannot find the exact board - v1.1 doesn't seem to exist and there are a lot of minor differences in the boards they do have so I don't particularly want to use incorrect drivers & possibly cause future problems. The system's gone back to it's owner now & I've asked him to let me know if he notices any non-operating bits or other problems so we'll wait & see.

Thanks again

That motherboard has an Intel chipset. Choose the second download (Intel Inf drivers) from this page
