unknown device and PCI System Management Bus drivers problems

can anyone help me resolve this problem. At startup of computer running 98se I get 2 prompts for unknown device and pci system management bus drivers which the computer nor myself can find

 

The PCI System Management Bus appears to be part of the Intel chipset drivers.

The original drivers will be on a CD that came with the computer.

You could look for updated drivers on the Intel website.

My guess is your system will be too old for using the identification utility so you will need to identify the motherboard using the BIOS string.

The motherboard model number will contain the chipset number.

Find and install the Inf Update Utility:

These will apply to non-branded computers. For a branded computer like Dell, Gateway, etc., look up the downloads at the manufacturer's website. Some manufacturers have proprietry drivers (eg. Hewlett Packard) and the drivers are only available on the CD that came with the computer.

Once you have the drivers installed for the PCI system the "unknown device" should be detected and may be automatically installed.
