Preface

Overview
The Intel® Chipset Software Installation Utility was developed for updating Windows* Operating Systems with the Plug and Play feature on Intel chipsets. The Intel Chipset Software Installation Utility is not required or compatible with Operating Systems without the Plug and Play feature, such as Windows NT* 4.0. This utility allows the operating system to correctly identify the Intel chipset components and properly configure the system. The Intel Chipset Software Installation Utility installs specific Windows INF files. The INF files inform the operating system how to properly configure the chipset for specific functionality, such as AGP, USB, Core PCI, and ISA PnP services. For more details about the specific INF files that are updated, please refer to the readme.txt file that is included with the Intel Chipset Software Installation Utility for Intel chipsets. These Release Notes outline the new features and key changes of this software since the last release. Additional information regarding troubleshooting, software sightings, and bug fixes is also included here.

5. | Software Sightings and/or Known Issues
Software Sightings and/or Known Issues
ID | Information
1 | This software will install the ICHxSMB.INF file on systems running Windows 98 Second Edition, even though the SMBus device is natively supported by the OS. This is done to allow the easy update of any future SMBus driver.
2 | During the Windows setup stage, the USB keyboard and mouse may not be accessible. This is because the legacy USB driver may be inactive when Windows enters the GUI mode. There is a small window of time when it may not be possible for the system to accept user input. Since the Chipset Software Installation Utility may cause prompts during the Windows setup stage, it should be ensured that the system BIOS support for legacy USB keyboard and mouse is enabled.
3 | When the Chipset Software Installation Utility is run on a system with Windows 95 Original Release, the Device Manager may report a memory resource conflict. This conflict involves the resources allocated to PCI cards that are located behind a PCI bridge. The operating system incorrectly reports a memory conflict even though the memory resources in question are fully contained within the PCI bridge aperture. This appears to be a known issue with the Windows 95 operating system. The Chipset Software Installation Utility operation has no effect on this issue.
4 | Older revisions of the Intel(R) LANDesk Software Package may cause a Device Manager warning when installed on a system after the Chipset Software Installation Utility has been executed on the system.
5 | When running this software on Intel PIIX4-based chipset platforms, an extra reboot message might appear after the operating system has completed setup.
6 | The Intel(r) Chipset Software Utility does not successfully install under the Microsoft* Windows* 2000 Finnish or Microsoft* Windows* 2000 Russian operating systems.
7 | The check for signature Block mode settings is not performed for the Windows* ME operating system environment.
8 | The ICH2CORE.INF and ICH2CORM.INF files are not signed for the Microsoft Windows 98 Gold version of the operating system. Microsoft is no longer signing specifically for the Windows 98 Gold operating system. The following devices will NOT be updated if BLOCK mode signing is enabled under Windows 98 Gold: 2440, 244E, 244C, 2448.
9 | When Installing the INF files prior to OS Installation on an ICH2-M based system using Windows 95 (all versions) Windows 98 or Windows 98 Second Edition, the user must ensure that the INFPreload.txt file has been edited to include a reference to the ICH2CORM.INF file. If these edits are not performed, then the ICH2-M bridge information will not be correctly installed. Below are the steps required to properly edit the INFPreload.txt file and ensure that the ICH2-M bridge information is correctly installed: Step 1) Edit the [PreCopyFiles] Section to refer to ICH2CORM.INF and comment out ICH2CORE.INF Step 2) Edit the [InfCopyFiles] Section to refer to ICH2CORM.INF and comment out ICH2CORE.INF Step 3) Edit the [SourceDiskFiles] Section to refer to ICH2CORM.INF and comment out ICH2CORE.INF
