4. Manual Installation
----------------------
  After installation, the following drivers are stored as listed.
      <Windows 95 directory>\System\AgartD.VXD
      <Windows 95 directory>\System\ALiPCIMP.PCI
  
  We can backup those files and install drivers manually in the future.
           
Windows 95:
  1. Copy AgartD.VXD to "<Windows 95 directory>\System\" directory.
  2. Add a key "AGARTD" in the registry:
     KEY:"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\AGARTD" 
     with: 
     NAME:StaticVxD
     DATA:"AgartD.VXD"
 
Windows 98 (M1541 chipset):
  1. Copy ALiPCIMP.PCI to "<Windows 95 directory>\System\" directory.
  2. Add a key "154110b9" in the registry:
     KEY:"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\PCI\GARTMINIPORT\154110B9"
     with:
     NAME       DATA
     --------------- 
     Instance   00 00 00 00
     Name       "ALi M1541"
     Path       "ALiPCIMP.PCI"

Windows 98 (M1621 chipset):
  1. Copy ALiPCIMP.PCI to "<Windows 95 directory>\System\" directory.
  2. Add a key "162110b9" in the registry:
     KEY:"HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\PCI\GARTMINIPORT\162110B9"
     with:
     NAME       DATA
     --------------- 
     Instance   00 00 00 00
     Name       "ALi M1621"
     Path       "ALiPCIMP.PCI"    

-----------------------------------------
5. Verifying Installation of the Driver
-----------------------------------------
  To make sure if the ALI AGP driver is properly installed,
  We need run "Regedit" and check whether the key AGARTD exists in 
  the following path
      "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD"
  for Windows 95 or the NAME/DATA pair 'Path  "ALiPCIMP.PCI" ' exists in
  the following path
      "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\PCI\GARTMINIPORT\154110B9"
      "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\PCI\GARTMINIPORT\162110B9"
  for Windows 98.

------------------------------------------------
6. Verifying Validation of the AGP Functionality
------------------------------------------------
  To check whether the AGP mechanism is able to activate, we can try the
  anyone of the following:
  1. a. Open the "Control Panel" folder
     b. Invoke "Direct X" icon
     c. Click on "Direct Draw" tab 
     d. Check if the video memory is more than the VGA card's memory.
        If it is, that means the AGP can be activated properly.
     If the "Direct X" icon doesn't exist, please get DirectX 5.0 SDK from 
     http://www.microsoft.com/msdownload/directx/dxf/sdk5.0/default.htm (
     idx5sdk.exe or idx5sdkm.exe). After unpacking, run setup.exe in the 
     root directory to start the SDK setup. Select "DirectX runtime only" 
     from the Setup Type selection dialog box.
  
  2. run ddtest.exe in the previous DirectX 5.0 SDK unpacking_dir\sdk\bin 
     directory. Click the "Connect" button. Check if the "Total Vmem" is
     more than the VGA card's memory. 
  
  3. get the debug or retail versions of the DirectX 5 runtime from previous
     WWW site (idx5dbg.exe or idx5rdst.exe). Run dxtool.exe in the 
     unpacking_dir\debug\directx or unpacking_dir\redist\directx. Check the 
     value of "DirectDraw\Primary Display Driver\Total Video Memory".
     
-----------------------------------------
7. Identifying the Drivers Version Number
-----------------------------------------
  The version of the drivers can be obtained by querying the driver file's
  properties under File Manager.

  After installation, the following driver are stored as listed.
    <Windows directory>\System\AgartD.VXD
    <Windows directory>\System\ALiPCIMP.PCI
  
  1. Invoke the "Explorer" application.
  2. Select the driver file.
  3. Open the "File" menu.
  4. Click on the "Properties" item.
  5. Click on the "Version" tab.
  6. The driver's version should be listed in the "File version" or "Product 
     Version".
