The packet driver demonstrates the use of the upper edge NDIS 3.0
services to communicate with NDIS MAC drivers.

The driver creates a device object which may be opened by Win32 apps
via a symbolic link.  A Packet may be sent by writing data to the
driver.  Receives may be pended to the driver by reading from the
driver.

The driver expects that it will be bound an Ethernet card as it makes
assumptions about frame size. If the driver is installed but the card 
doesn't exist, there will be a warning message box shown after the invalid
card is chosen at the first dialog. 

There are 4 necessary files:  
1. Oemsetup.inf   ------ the setup file
2. packet.sys     ------ the packet file
3. packet32.dll   ------ the AP DLL file
4. NT4Diag.exe    ------ the AP file

The install procedure is as followed:
1. Make sure that Oemsetup.inf, packet.sys and packet32.dll are in the
   same directory.
2. Choose "Start" --> "Setting" --> "Control Panel" --> "Network" -->
   "Potocols"
3. Press "Add..." and "Have Disk..". Key in the directory which is mentioned
   in step 1. The NT will start installing when you press "OK" in the 
   "Select OEM Option" dialog box.  
4. Check the item "Service" to see if "Ndis 3.0 Packer Driver" is shown.
   If yes, press "Close" and restart the computer. If not, repeat step 1 and
   try again.
5. Copy the execution file "NT4Diag.exe" to anywhere you want. 



Note: 1. Be sure to restart the computer after installation.
      2. Remove other protocols, if they disturb the test seriously.
      3. The function buttom of "Receive" in NT4Diag.exe v1.1 shows the test pattern only,
	 while NT4Diag.exe v1.0 shows each packet that NIC receives.
