Driver for Vista x64 (64 bit) – Unknown device on Intel(R) ICH8/ICH8R Family LPC Interface Controller – 2810

Upon installing Vista x64 on an , there were a couple devices in Device Manager that were missing drivers. The first was for the Attansic L1 Network Card, for which ASUS had a driver on their site.  The 2nd was an unknown device. Right clicking and going to Properties showed the location as “Intel(R) ICH8/ICH8R Family LPC Interface Controller – 2810”.

Thinking that maybe the Intel Chipset INF package might have the driver, I installed it. No such luck. Finally, I did a search which brought me to a couple other pages, the biggest help being from a post by d.chatten on, although a post was helpful as well. As it turns out, it’s for a device called the ATK0110 which may have something to do with legacy I/O.

Regardless, the link in the post was broken (asus vs ASUS), so I browsed to looking for the file, but noticed a file which, since it has “Vista” in the name, I thought I’d try first. The steps I took were:

  • Downloaded to the desktop (link at the bottom of this post)
  • Extracted the files
  • Device Manger –> right-clicked the unknown device, chose “Update Driver Software”
  • “Browse my computer for driver software”
  • Next
  • Installed!

Pretty simple stuff – it told me the “ATK0110 ACPI UTILITY” was installed, and that was that. It’s also worth noting there’s a regular “Acpi” folder which I’m guessing is a 32-bit version. Both the “Acpi” and “Acpi64” folders contain a “win2000” folder in addition to the “WINVISTA” folder, so to sum it up, I’d guess that it’s got the drivers for 32/64-bit 2000/Vista.

In case the ASUS site has a heart attack (or just plain moves stuff around enough to break a direct link), I’ve put up a copy of the file:

  1. Thanks a lot! This helped me so much. I was searching a long time for this one. 🙂

  2. Hey man thanks a lot this is almost my problem..

    I did the same thing I had Vista 32bit and then I installed 64bit and now i have one Unknown device on Intel(R) ICH8M-E LPC Interface Controller – 2815 so i guess its pretty much the same.Can you help me to find it?

    • HellFlyer:

      I did a quick google search, but there were piles of results. You could start there if you’ve got the time.

      Otherwise, (1) take a peek at the CD that came with your motherboard (if you’ve got it). It could be on there. (2) Try the Intel Chipset INF package from Intel’s website. (3) Finally if neither of those work, head to the motherboard manufacturer’s site and check the section there for your motherboard – if it’s still a no-go, toss them an email.

  3. Matt, you are my hero! After an hour of pointless searching on ASUS and Intel web sites I found your page via Google. Worked like a charm on my P5B-E!
