Just and FYI for the yellow or triangle with and exclamation point in Device Manger after installing / upgrading my HP 510 DT p024 Desktop to Windows 11. I tried the solution mentioned in other posts
but after installing sp101171.exe and rebooting nothing changed. Still had the same issue showing up in device manager.
TITLE: Intel Chipset Installation Utility
VERSION: 10.1.18243.8188
DESCRIPTION:
This package contains the Intel Chipset Installation Utility. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager.
PURPOSE:
SoftPaq NUMBER: sp101171
SUPERSEDES:
EFFECTIVE DATE: 01/03/2020
SSM SUPPORTED: Yes
LANGUAGE(S):
English (US)
ENHANCEMENTS:
- Provides the updated Intel Chipset Installation Utility driver.
TL;DR
Solution:
Right click Unknown Device named “PCI Data Acquisition and Signal Processing Controller driver" and click Update driver and browse my computer and i typed C:\ and that found an old serial uart (which I think is a dial up modem driver) and the hardware item was added int he long list of itmes under System Devices as "Legacy Device"?. I don't think it has any impact on the system but I don't like having driver errors becasue it makes it harder to troubleshoot when there is a problem.
