I have setup and assembled an Intel P4 Orignal M/B built in sound and VGA, with all requirements, the pc boots up fine but in the device manager i see a yellow exclamation mark, it saya PCI device unknown. The PCI modem is detected but it is not recognized as a modem rather it assumes it to be a pci device and when asks for the driver it does not accept the modem driver. Please help

It may not be the modem it has a problem with. start by removing the modem. Check for the problem to still be there. delete the offending item. reboot windows and let it do another search for new hardware. get your system working without any errors before adding the modem back in. Then install the modem and use the have disk. The fact that it is a voice modem ( has two connections) may be enough to cause a conflict with the onboard sound if the onboard sound does not get in the registery first. I had this same problem when adding a sound blaster card and modem at the same time and it was hard to tell which was acting up and there was no way to know which was the offending party. Hope this helps.

Check your documentation on the modem. Undoubtedly this is what is tripping you up. You may need to install the drivers in a certain order or there may be multiple drivers included with your install CD (not all of which are correct). I would start out by removing the present modem. Then reinstall it and use the latest driver from the manufacturer (download this from their website). Hopefully that will resolve your problem.

Good luck!

Depending on your operating system, (W98 and Me inparticular) you need to install the INF driver for the motherboard before it can properly recognize PCI cards.

I would download the latest driver from Intel, and transport it to this system.
Or, it should be on the CD that came with the motherboard.

It is likely that you need to install a specific controller chip for the modem in order for the modem to be recognized and installed. Instead of choosing to install a modem, let windows look for a driver but specify the location yourself. Downloadthe latest driver for the modem and uncompress the files contents to a new folder. That folder is where you should have windows look. The first device that is installed will probably be some sort of controller or communications device, then the modem will automatically be detected and install.

Disable your com ports in the bios, and remove them in the OS. If it works after that, it was a hardware conflict, as the modem will be using the same IRQ and Port as the com port.

If that fails, try the modem in a different slot, and try upgraded drivers.

I have encountered a similar problem with a P4 motherboard recently and decided to let WindowsXP search the motherboard driver CD for the drivers. It decided the unknown device was something to do with Power Management and installed the drivers. The system was no longer able to boot and I had to go back to Last Known Good configuration. Just a warning.

Is there anything not working? If there is, then it's a problem. If everything works, leave it and get on with your life. Nobody is perfect.

in this case maybe you want to try to change some setting on the bios, see if it the internal modem is enable or not.
or you can try to check the selected irq, to see if got any corruption

Look no further. Only try to find the modem drivers for that specific OS. This will solve your problem. That unknown device is only the modem but you have to have the perfect matched drivers.
