		 INSTALLING MICROSOFT WINDOWS NT DRIVERS FOR
                  THE HP DeskDirect 10/100 PCI LAN ADAPTERS

 The HP DeskDirect PCI network adapters come with a 32-bit NDIS 3.0 
 driver which support both a high performance bus master and I/O-mapped
 mode of data transfers. It is recommended that the bus master mode be used 
 unless your system does not support bus mastering.  The Microsoft Windows NT 
 network setup uses a file OEMSETUP.INF to determine the driver information 
 for the HP PCI LAN adapter you have installed in your computer.  

 The NDIS 3.0 driver and its OEMSETUP.INF file is located in the 
 HP Support Disk directory:

     \NT\HPDDND3.SYS

 NOTE:  The Novell Netware Windows NT Requestor does not use this driver.
        See the file \NOVELL\README.NT on the HP Support Disk.
 
 NOTE:  Throughout these instructions, the term 'HP LAN Card' will be used
        to refer to the HP DeskDirect 10/100 PCI LAN Adapter.

 Use the following instructions to install the HP LAN Card and its Windows NT
 driver:
 
 1.  Install the HP LAN Card into the computer.
 
     Follow instructions in the 'Setting Up Your Card and LAN Connection'
     sections of the Installation Guide and the computer documentation for 
     the correct procedure to install an adapter into the computer.  See the 
     topic on "Interrupts Sharing" in the file /TECHNOTE/PCI_INFO.TXT.  Ensure 
     that power has been disconnected from the computer before opening the 
     computer's case.

 
 2.  Configure and test the HP LAN Card.
 
     Reconnect power to the computer and boot DOS.  Run the HP configurator
     on the HP Support Disk.  For example, if the Support Disk is in floppy
     drive A, execute the following commands at the DOS prompt:
 
 	A:
 	HPVGSET

     If you wish to use the adapter in full duplex mode, use HPVGSET to
     enable that option now.
 
     Select "Card Test" to verify the adapter.  After it passes, select
     "Exit program".
 
     Connect the LAN cable to the HP LAN Card.
 
 
 3.  Install the Microsoft Windows NT SETUP utility.
 
     Locate the Microsoft Windows NT System Guide and the Microsoft 
     diskette labeled "Windows Setup Disk #1" if you are installing from
     floppy disks or "Setup Disk for CD-ROM Installation" if you are 
     installing from CD-ROM.
 
     With the computer turned off, insert the Microsoft diskette in drive A,
     and then turn on the computer.  
 
     Follow the instructions on each window to install Windows NT. One of 
     the steps in the installation is selecting the network adapter driver. 
 
     For Express Setup, Windows NT Setup automatically checks for a network
     adapter and installs the first one it recognizes.  Windows NT Setup 
     cannot detect HP network adapters so it will continue and ask if you
     want to install Microsoft Remote Access Service.  If you do not choose
     to install Remote Access Service, Setup displays the Network Adapter
     Setup dialog box and asks you to select an adapter from a list.  When you 
     get to that point, continue your installation following the instructions 
     in step 4.
 
     For Custom Setup, Windows NT Setup asks if you want it to detect the
     network adapter in your computer.  Select the "Do Not Detect" button.  
     Setup will then display the Network Adapter Setup dialog box and asks 
     you to select an adapter from a list.  When you get to that point, 
     continue your installation following the instructions in step 4.
 
     If you want to add the network driver after Microsoft Windows NT has 
     been installed, select the "Network" icon in Control Panel.  When 
     "Network Settings" window appears, select "Add Adapter" to start the 
     process of adding the LAN Adapter network card into your Microsoft
     Windows NT environment.
     
 
 4.  Select the network adapter driver.
 
     Use this Support Disk and follow the instructions given below to configure
     your HP LAN Card.
 
     When the "Network Adapter Setup" dialog box shows up, use the arrow keys 
     to highlight the line:
 
 	<Other> Requires disk from manufacturer
 
     Click on the "Continue" button to select this item.
 
     When the "Insert Diskette" window appears, insert this Support Disk into
     floppy drive and enter the path name at the prompt. For example, if
     the diskette is in floppy drive A, then enter:
 
 	A:\NT

     to install the driver.

     When the "Select OEM Option" window appears with the lines:
 
 	HP DeskDirect (J2585A) 10/100 PCI LAN Adapter
 	HP DeskDirect (J2585B) 10/100 PCI LAN Adapter
 	HP DeskDirect (J2970A) 10BaseT/10Base2 PCI LAN Adapter
 	HP DeskDirect (J2973A) 10BaseT PCI LAN Adapter
 	
     use the arrow key to highlight the line indicating your adapter and press
     the ENTER key to select it.
     
     Then, Setup will load all the required driver files.  The network
     adapter driver file resides in the \NT directory of this Support Disk. 
 
     NOTE: If there was an HP DeskDirect 10/100 LAN Adapter already installed 
           in your computer, NT may fail to properly copy the new driver from 
           the Support Disk.  If this occurs, copy the driver file "HPDDND3.SYS"
	   from the \NT directory of the Support Disk into the
	   <NT>\SYSTEM32\DRIVERS directory on your computer (where <NT>
	   is the root directory of the NT system files).  To copy the driver
	   manually select the disk driver where NT is installed (e.g. if NT
	   is on the E drive then type E: and press the RETURN key) and perform
	   the following steps:
 
	       CD \<NT>\SYSTEM32\DRIVERS
               REN HPDDND3.SYS HPDDND3.OLD
 	       COPY A:\NT\HPDDND3.SYS HPDDND3.SYS
 
 5.  At this point, all the steps required for the installation of network 
     driver are done.  If you are in the process of installing Microsoft
     Windows NT, proceed with the Windows NT Setup program until the complete
     setup procedure is done.
     
     The installation and/or changes of network configuration will not take 
     effect until the computer is rebooted.
 
 

 Diagnosing Problems by Examining the Event Log
 ==============================================
 
 If the driver fails to start or does not appear to be working correctly
 the Event Log should be examined for any driver diagnostic messages.
 
 
 A.  Start the Event Viewer applet in the Administrative Tools group in
     Program Manager.
 

 B.  Search the Event Log Source column for any entries named "Hpddnd3".
    
     Double click on the entry to examine the Event Detail dialog box.
     The upper half of the box gives a short generic description of the error.
     In the lower half of the box is a hex and ASCII dump of error data.


 C.  Scroll through the error data ASCII for any readable strings.
 
     If a readable string is present it will describe the problem found in
     more detail.
     
     If no readable string is present this typically indicates that the driver
     failed early in the process of loading usually due to a resource conflict
     (e.g. I/O port conflict).
