Intel Chipset Compatibility with Microsoft Windows
Background Information
Microsoft* Windows* operating system uses device information files (*.INF) specify define characteristics various controller device classes operating system. certain classes, device controller's Device must explicitly listed file optimal operation. Historically, release schedules Intel chipsets Microsoft operating systems have aligned; therefore, Device some Intel chipset components listed versions Windows* This Application Note describes additions required Windows* .INF files complete Intel chipset support, Intel(r) 440GX AGPset.
Windows* Versions .INF Files
Since Windows* "Gold" retail release (August 1995), Microsoft released three complete operating system updates prior release Windows* June, 1998. various Windows* releases their respective version numbers listed below. Windows* Versions Retail release ("Gold") Version .950 Service Release ("OSR1") Version .950a Service Release ("OSR2") Version .950b Service Release with Supplement ("OSR2.1") Version .950b letter update) Service Release ("OSR2.5") Version .950c (Windows* version information obtained System applet Windows* Control Panel.) Each five Windows* versions listed above contains unique .INF files. From Windows* Gold release Windows* release, number .INF files increased operating system been enhanced support many device classes. Additionally, content core chipset .INF files increased, later versions Windows* inherently identifies relatively chipset devices. This Application Note addresses changes required three .INF files, namely: MACHINE.INF (contains core chipset device names) MSHDC.INF (contains controller device names) USB.INF (contains controller device names) These files usually found C:\WINDOWS\INF, although WINDOWS directory name differ depending Windows install convention used.

Editing .INF Files System Testing
following procedures used modify MSHDC.INF, MACHINE.INF, USB.INF files system testing. strongly recommended that edited MSHDC.INF MACHINE.INF files present time Windows* installation. Although MSHDC.INF MACHINE.INF files edited after installation, this procedure discouraged potential system lockup (see Section 4.5). update USB.INF file, Windows* OSR2.1 OSR2.5 must installed first.
Note: Note:
Incorporating MACHINE.INF MSHDC.INF Files Time Windows* Installation
This only acceptable procedure Windows* OSR1 This suggested procedure High Volume Manufacturing Windows* distribution contains \CAB directory containing operating system .CAB files installation program. name directory vary depending distribution (i.e,. \WIN95\*.CAB, etc.). Copy .CAB files installation files from Windows* directory directory hard disk. recommended prepare subdirectory with necessary .CAB files .INF files perform installation from this subdirectory. This procedure requires large amount disk storage. important make sure this enough disk space before beginning copy process. Extract MACHINE.INF MSHDC.INF files from .CAB files contained your Locate EXTRACT.EXE program either your system. extraction with following commands: EXTRACT PRECOPY1.CAB MACHINE.INF EXTRACT PRECOPY1.CAB MSHDC.INF This command will start with PRECOPY.CAB file work through chain .CAB files until finds MACHINE.INF MSHDC.INF saves them your current directory. Make copy existing MSHDC.INF MACHINE.INF files then edit both files according procedures listed above. SETUP.EXE install Windows* After setup complete, view devices Device Manager ensure devices configured correctly. using Windows* Gold OSR1 releases, devices should correctly this time. using Windows* OSR2.1 OSR2.5, will configured correctly until Supplement been installed USB.INF file been updated correctly. view Device Manager: Control Panel System applet Click Device Manager Click View devices connection Click Plug Play BIOS Click Confirm none "PCI bus" devices preceded with yellow symbol. Figure shows example correct configuration devices.

Select restart system. (For warning, Section 4.5) Windows* will display messages when various hardware components system recognized. When prompted install driver, select Windows Default Driver appropriate device drivers from disk provided hardware manufacturer, needed. Select restart system. (Steps 10-11 occur several times.) Re-install custom drivers from disk provided hardware manufacturer, needed.
Note:
Editing MACHINE.INF MSHDC.INF Files After Installation
Please note that this method updating system files recommended. preferred mechanism incorporate updated MACHINE.INF MSHDC.INF files time installation described above. Also, this procedure Windows* OSR1 based systems. Make copy existing MACHINE.INF MSHDC.INF files. C:\> \<Windows Path>\INF C:\<Windows Path>\INF> COPY MACHINE.INF MACHINE.000 C:\<Windows Path>\INF> COPY MSHDC.INF MSHDC.000 Edit MSHDC.INF MACHINE.INF files, adding necessary information described Sections 3.2.

Restoring Original MACHINE.INF, MSHDC.INF, USB.INF Files
desired restore original MACHINE.INF MSHDC.INF file: Make copy existing MACHINE.INF, MSHDC.INF, USB.INF files Restore original MACHINE.INF, MSHDC.INF, USB.INF files C:>CD \<Windows Path>\INF\ C:\<Windows Path>\INF> COPY MACHINE.000 MSHDC.INF C:\<Windows Path>\INF> COPY MSHDC.000 MSHDC.INF C:\<Windows Path>\INF> COPY USB.000 MSHDC.INF Delete from Device Manager doing following: Control Panel->System applet. Click Device Manager Click View devices connection. Click Plug Play BIOS. Click bus. Select Remove. (For warning, Section 4.5) Select restart system. (For warning, Section 4.5) Windows will display messages when various hardware components system recognized. When prompted install driver, select Windows default driver appropriate device drivers from disk provided hardware manufacturer, needed. Select restart system. (Steps 10-11 occur several times.) Re-install custom drivers from disk provided hardware manufacturer, needed.
Warning Potential System Lockup
System lockup occur during Device Manager Remove operation Control Panel Restart result possible system issues during these operations. event system lockup, restart machine view Device Manager. devices listed properly system experiences further problems, then .INF file update process successful. devices configured correctly further problems experienced, re-install Windows repeat editing process using pre-install method described above.
