ICH7

Motherboards Asus P5LD2VM and a Toshiba Tecra A8 both have the ICH7 chipset
and display the same problem.

Immediately after WXPPro is installed, before any other drivers or patches
are added, installing Intel's Chipset Software Installation Utility (7.1,
7.3, 8.01 or 8.1), both motherboards display an `unknown' device in the
device manager.

82801GBM LPC Interface Controller.

An identical entry also exists in the System Devices with the driver
properly loaded. It doesn't seem to affect functionality...

What gives?

Possible mismatched driver. Re-install the motherboard's
chipset drivers, either downloaded from the Asus website
or from the cdrom.

I thought the same too, but I have tried both the Intel native version of
the CSIU, and the respective
motherboard manufacturer's custom version of the CSIU on virgin WXPPro.sp2
installations for both the Asus and the Toshiba.

This is the only device on both mobos that is outstanding.

IIRC, only one version of the chipset drives (and this includes
ICH7) can be installed --- either the motherboard's OEM version
or the Intel version. The recommendation was to use the OEM-maker's
version or copy. Also, ICH7 covers a number of different items and
it would be worthwhile to make sure that all of them are accounted
for, including SATA.

sigh...

Just to be absolutely clear here about what I'm doing:

1. wipe hdd
2. install WXPPro.sp2
3. install one set of Chipset Software Installation Utility drivers (Intel,
or OEM, from versions 7.0 up to 8.1; 6 different versions)
4. all other system and expansion drivers installed and accounted for
5. unknown device remains despite identical entry in system devices
6. lather, rinse, repeat at step 1, changing driver package at 3.

This specific `unknown device', the 82801GBM LPC Interface Controller, shows
up identically, but properly 'drivered' in the system devices. This is
occuring on two very different manufacturer's motherboards, through 6
different driver packages, whether they be Intel or OEM (Asus and Toshiba).

What I'm hoping for by posting to this ng is that someone may have also
built up an Asus P5LD2VM that this did not occur on, and which driver
package(s), version or order they used to do so.

The only thing that comes to mind is that perhaps setting the BIOS of the
ASUS to use S3 could account for this... the Toshiba however, has no option
like this... using TPM; another fine kettle of fish; and their proprietary
windows only BIOS configuration program... so I'm scratching my head here.

LPC Controller = Low Pin Count Controller. It's a single interface for
all of the legacy devices in a PC (serial ports, parallel ports, floppy
drive, typically, with some variation).

It's driver is supposed to be in the chipset software. You are not the
only one who has this issue, however, a google search found other people
looking for the driver for the LPC Controller.

Not sure that you are doing anything wrong, or that there is anything
you can do about it.

Windows is particularly flakey with its error messages,
especially when it comes to resolving "unknown devices".
There were times when the only way to discern what the
device that was supposed to be operating (or not) was the
warning icon in Device Manager and a PCI/VEN number. And
this usually reflected the failure to install some obscure
driver because some setting was inadvertantly toggled in
the bios settings via the desktop management interface.
One might want to consider re-setting the bios to default
or to do a line-by-line check.

Yeah, I see another user had this problem due to the lack of an "Intel Quick
Resume Technology Driver" only associated with XP Media Center Edition.
He had to disable a setting in the power management section of the BIOS for
the unknown device to be removed.
Might be something to do with the common integrated Intel Graphics
accelerator.

Your are possibly looking for this interface driver (ATK0110) or one
like it by a different name.

It is sometimes (hidden) on the manufacture's installation CD.

Install by pointing to manufacture's original CD root and let windows
grind through and find it to update.

Shows up as unknown device in hardware list but clears list as it
really installs in System Section.

Also may be missing a "mass storage" driver which will clear the list
even though no such device output is provided for to my knowledge on
the laptops.

The Intel chipset utility will not clear the condition.

Call manufacturer to save time if "No Joy".
