PCI Serial Port driver missing

I have an Intel DH55HC board with an i5 CPU and I'm running Win7 64bit OS. From the first, it was telling me I lacked a "PCI Serial Port driver" and I am unable to find these through Device Manager. Device Manager only says devices in these slots cannot work because they have no drivers. I have also searched Intel's site without success. Nothing inserted in the board's PCI slots or in its PCI x1 slots will operate, although the PCIx16 slot seems to work fine- I have a graphics adapter in that one. Perhaps I am missing the obvious, but this is a serious problem with this board, and I would very much appreciate some advice.

    If you go to Intels website and ensure all the relevant drivers for your motherboard (including the Intel ME Management Engine driver) are installed, you shouldn't have device manager complaining with an exclamation mark anymore. Let us know how you get on.

    A big thank you to Flying_Kiwi, whose advice worked. I carefully worked through all the relevant drivers on the Intel site, and now have those slots working away as they should. Chalk it up to the learning curve and again- thanks.

    Glad to know it's now sorted. That cryptic name for the missing device doesn't help but my DG45ID comes up with a similar message if the ME driver is missing - that's how I knew.

    Well, I thought I had overcome the problem with reloading the Intel board drivers, but I guess I only shifted it. I gave up trying to make the video card in the PCI 1x slot work and tried another card (Sparkle PCI 8400GS) in a standard PCI slot. (My goal is to set up three monitors, two from the primary video card in the PCIexpress 2.0x16 slot, and one from another card.)The Sparkle card cannot start either: Device Manager says I have a code 10 on the PCI standard PCI-to-PCI bridge. Troubleshooting to configure a device says "PCI to PCI bridge is missing a driver". When I try to update the driver in Device Manager, it says I have an up to date driver installed.

    I have very carefully gone through all the drivers I can find on the Intel download site for my board (DH55HC) and seem to have all the latest installed. I have also updated my bios. I am very happy with the overall performance of this board, but still have this persistant problem. At this point, I am unsure where to look for a solution.

    Thanks!

    There is only a limited memory space that can be filled with devices that use memory at boot time. If you set up a PC to have many devices using that boot memory, sometimes there just isn't enough left and as a consequence some things may not function as expected. I've encountered this sort of problem before with using both a network bootable NIC, a fancy graphics card and a RAID card all in the same PC and I found I had to replace the NICs boot footprint with a smaller one by flashing a special (less complex) firmware package onto it in order for it to work as expected. Perhaps you're encountering similar issues with all the devices in this PC? Have you reset the BIOS to load default values and made sure nothing is 'forced' in terms of configuration? If so, I'd get in touch with the PCI graphics card supplier and see what they have to say about it. You may have to do a bit of trial and error card juggling around into different slots (if you have the option) to see if that gets things working.

    Dear Flying_Kiwi:

    Once again you have given me a very solid reply and much food for thought, and I thank you. I will check out the BIOS default values as you suggest. I try to keep the start up as lean as possible, but there may be room for some more triming. I do have four HDDs, but they are not in RAID and I use them just to help keep things sorted out. Slot juggling is out, as the graphics card is fat and therefore covers a slot as well as uses one, and I have a sata card in the third PCI slot.

     

    I've also thought about swaping mother boards for a bit more robust one. Would I be able to load my OS to a new board, or just get myself into more trouble?

     

    Thanks:

    Sorry to hear that slot juggling was not an option. It's not a matter of robustness as to whether this problem crops up and at the time I was experiencing the issue, swapping to another motherboard would have made little difference. If you do decide to go down the different motherboard path, you may want to get the supplier to test one out with your system first. The last thing you want is to buy it and have the same issue.

     

    Personally, I'd first be loading default values in BIOS and if that makes no difference then contact the manufacturers of your cards (and/or search their websites) to see if updated lower memory footprint firmware revisions are available to address the issue. Loading your existing OS with a new motherboard should be OK but if it's an OEM version of Windows it may refuse to activate, in which case you'll need to liaise with Microsoft explaining what you've done to obtain a new code.
