what is Intel LPC Controller @ hardware manager?

webwilli · 08-03-2004, 05:44 PM

i have installed an asus p5gdc (grantsdale) motherboard. after winxp fresh installation, i had a yellew ? (unknown hardware) in the hardware manager. the newest intel driver was installed but no changes... i installed asus ai booster for a test and the ? was gone!! also i have checked the ai booster setup dir and find a dir named "acpi". In this dir was a driver for the unknown hardware.

my questions:

1. what does the atk0110 driver?
2. where can i get a newer version? this ver here is from last year.
3. now i have two LPC Controller in hardware manager. what does a LPC Controller do?

thx...

Wrong Forum for this thread, so I am moving it to Intel Chipsets, where you will get more attention for your question.

ups...

thx

No problem, glad to help. BTW, I don't have your board, but I think you may have some incorrect bios settings which is what is causing the problem. Probably in the Power bios menu. BTW, I love your city, great place.

I spent a couple of weeks there on business a few years ago. I had my family along - it was summer, we had a lot of fun.

Check out the Power settings, normally you want APM to be disabled and APCI to be enabled along with ACPI 2.0, but not having your board, I am not sure what your correct settings should be.

i have copy the bios settings from the pdf manual

see att...

my settings:

Power Menu
Suspend Mode: auto <- i don´t use it...
ACPI 2.0 Support: no
ACPI APIC Support: enabled

APM Menu
all settings equal like pic

Try turning on the 2.0 support. I think you need that for a HT CPU.

webwilli · 08-03-2004, 06:35 PM

ACPI 2.0 enabled. no change.

crazy thing.

I have asus P5gdc pro motherboard, when I installed WindowsXP with sp2 yesterday, this problem came too.
I checked the bios, nothing found;checked "Windows Upgrade", nothing found too.When I checked the ID:atk0110, I found here.
Today, this problem has gone. Now, it shown as "ATK0110 ACPI UTILITY", however, I don't know how it works, and what function it provide.
At first, all of my harddisk paritition is NTFS, when it showned as "Unkown Device"( of cause, in chinese).This morning I was about to clone my system by using ghost utilty, so I had to trasfer one of my partitions to FAT32. And then, the miracle came.
I never came here before, but I wrote this down, maybe can do some help.
BTW: My English is not good, if any error occurs, show some mercy. ^_^

This had me baffled for quite a while too. This discussion was the only sensible thing that came up from Google about it.

I think this device allows the Ai NOS crap to work (dynamic overclocking and stuff). It may be Asus specific which is why instaling the Intel chipset drivers don't help. If you don't want to install the Asus overclocking tools but just want the device manager error to go away, you can install the driver without all the supporting software.

Put the chipset support CD in. Don't let it auto-run, or just kill the autorun program if it does.

Go to hardware manager, right click on the ? device, say "Reinstall driver".

Choose custom location

Be sure your CD-ROM is included in the list of places to look

Windows will recursively look through the .inf files on the CD and install the appropriate driver. Didn't even need to reboot.

lpc is the Low Pin Count controller. this is where all older isa devices are located. lpt, com, thermal asic (application specific integrated circuits) for thermal monitoring, etc. lpc lowers the pin count of the integral devices and allows them to be able to use pci tranfers and sometimes isa for compatiblity.

when reading the posts i noticed incorrect bios selections. you should have acpi 2.0 enabled. this is a must for proper hyperthreading operation. not version 2.0 but acpi in general. acpi is plug and play, thermal management, other system specific configurations and communication all rolled into one. usually, on some boards when acpi is enabled, apic will be enabled along with it. if there is a apic selection, this should be enabled also-which your motherboard does (this is important for multiprocessor and hyperthreading systems). however, since you are using windows the previous installation hal will be overwritten to a new one. many will argue this, but a reinstall should be performed when any hal change is made. even microsoft has posts on how to circumvent this, but it is not recommended and i concur
