HP Evo D500 Using Windows 95 on Compaq Evo Desktop Computers - Page 4

WHITE PAPER (cont.) ... SETTING UP YOUR COMPAQ EVO DESKTOP PC TO WORK WITH MICROSOFT WINDOWS 95 The Windows 95 "Patch" When Windows 95 was released by Microsoft, processor speeds were much slower than they are today. Windows 95 contains "speed-sensitive code" that causes operating system lockups on computers equipped with newer, faster processors. This was first noted with the AMD K6 processor. The software patch referred to as the "AMD K6 Patch" allows Windows 95 to function correctly on systems with fast processors, including those found on the Evo Desktop PCs. It is important to note that this patch is not AMD-processor specific; it merely reflects the name of the first processor with which Microsoft noted the issue. For additional information about this patch, you may refer to Microsoft Knowledge Base Article Q192841, found here: http://support.microsoft.com/support/kb/articles/Q192/8/41.ASP?LN=ENUS&SD=gn&FR=0&qry=Q192841&rnk=1&src=DHCS_MSPSS_gn_SRCH&SPR=W95 On some platforms, including Evo Desktops, the patch cannot be run by following the procedures outlined in the Microsoft Knowledge Base article, because the affected platform cannot start Windows 95 in Safe Mode. The following alternate procedure can be used in these cases: 1. Connect to the Internet and browse to the Microsoft Web site at http://www.microsoft.com/windows95/downloads/contents/WURecommended/S_WUServicePa cks/AMDPatch/Default.asp to download AMDK6upd.exe. 2. Save AMDK6upd.exe to a bootable floppy disk. 3. Extract the files from AMDK6upd.exe to the floppy by executing: AMDK6upd.exe /T:a:\ /C Switches are documented; run AMDK6upd.exe /? for more information. 4. Start the Windows 95 installation, following normal procedures. 5. The first time you start the computer after installing Windows 95, an error may occur, or the computer simply many not start. Insert the diskette created in step 2, above, and restart the computer. 6. Manually copy the updated driver files on the diskette to the hard drive folders shown below.* You can create a batch file to perform this task if you need to do this on many computers. Locations for each of the files are: scsiport.pdr - copy to C:\Windows\System\IOSubsys disktsd.vxd - copy to C:\Windows\System\IOSubsys esdi_506.pdr - copy to C:\Windows\System\IOSubsys hsflop.pdr - copy to C:\Windows\System\IOSubsys cdfs.vxd - copy to C:\Windows\System\IOSubsys vfbackup.vxd - copy to C:\Windows\System\VMM32 ios.vxd - copy to C:\Windows\System\VMM32 int13.vxd - copy to C:\Windows\System\VMM32 * These paths assume that Windows 95 is being installed to C:\Windows. If a custom path was chosen for the Windows 95 installation, you will need to change the paths above to reflect the appropriate subdirectory. 15LA-0901A-WWEN 4
