                        INSTALLATION INSTRUCTIONS FOR THE
                        HP DESKDIRECT LAN ADAPTER (J2973A)
 
 
 These instructions are used to install and test the HP DeskDirect LAN Adapter.
 The adapter is used in a PCI slot in the computer to connect to a 10-Mbit/s
 twisted-pair (10Base-T) LAN.
 
 More information is available in the printed manual that accompanies this
 LAN adapter.
 
 This LAN adapter can support three modes of data transfer:  bus master,
 I/O-mapped, and memory-mapped.  If a bus master PCI slot is not available
 on your computer, or if a bus master driver is not available for your
 network operating system, the LAN adapter can operate in I/O-mapped or
 memory-mapped mode.
 
 
 Procedure
 =========
 To install, configure, and verify the HP DeskDirect LAN Adapter, follow
 this procedure (detailed in the manual):
 
 
  1. Install the HP DeskDirect LAN Adapter into a PCI slot in the computer,
     preferably a PCI slot with bus mastering enabled.
 
     NOTE: Ensure that power has been disconnected from the computer before
           opening the computer's case.
 
     Follow the installation instructions in your printed manual, along
     with the computer documentation for installing an accessory board
     into the computer.  Do not yet attach the LAN cable.
 
 
  2. Test the LAN adapter by doing the steps listed below.
 
     PCI computers feature Plug-and-Play configuration of PCI adapters.
     When the computer boots, the PCI BIOS will assign to each PCI adapter
     the resources that may be needed.  For this LAN adapter, these include
     I/O address range, interrupt (IRQ), and memory map address range.
 
     A) Reconnect power to the computer and boot DOS.
     
     B) Run the HP utility "HPVGSET" on the HP Support Disk to verify that
        the Plug-and-Play PCI BIOS successfully configured the LAN adapter.
        For example, if the HP Support Disk is in drive A, enter the
        following commands at the DOS prompt:
              A:
              HPVGSET
 
        NOTE: If more than one HP DeskDirect LAN Adapter is installed, then
              use "Select Card" to select the specific adapter to test.
                          
        NOTE: If HPVGSET fails to find the HP DeskDirect LAN Adapter, see
              the section "Installation Problems" below.
 
     C) Select "Card test" to verify the adapter.
 
        NOTE: The Plug-and-Play PCI BIOS may assign the memory map address
              range above extended memory; if so, HPVGSET attempts to
              temporarily move the memory map addresses to an empty block
              of the upper memory area to complete its testing.
 
        NOTE: All three transfer modes (bus mastering, memory mapping, and
              I/O mapping) are tested, to allow any of these modes to be used
              by the driver selected in step 6 below.  Any resources not
              needed after that step, such as memory map addresses, will be
              turned off.  Since bus mastering allows for the fastest data
              transfer, bus mastering will be used by default by the drivers
              where possible.
 
        NOTE: The bus master test will fail if the LAN adapter is installed
              in a PCI slot not enabled for bus mastering.  Do one of the
              following if this bus master failure occurs:  (1) enable  bus
              mastering on the slot (following the computer's documentation),
              or (2) move the LAN adapter to another slot that is enabled
              for bus mastering, or (3) in step 6 below select a driver for
              I/O-mapped or memory-mapped mode (an "IOMEM" driver).
 
 
  3. After "Card Test" passes, connect the LAN cable to the adapter.
 
 
  4. [Optional] You may do a preliminary test of the adapter's ability to
     communicate on the link by selecting "Link test" in HPVGSET.
 
 
  5. To quit HPVGSET, select "Exit program".
 
 
  6. Install the network driver.
 
     The HP Support Disk contains the driver files that allow the LAN
     adapter to be used with the networking product on the computer.
 
     Run the HP utility "SETUP" on the HP Support Disk to view the driver
     installation instructions.  For example, if the HP Support Disk is in
     drive A, enter the following commands at the DOS prompt:

           A:
           SETUP
 
     NOTE: If the HP DeskDirect LAN Adapter is installed in a non-busmaster
	   capable slot, bus master mode (the fastest) cannot be used.
	   Instead select a I/O-Memory (IOMEM) driver, which will use
           memory-mapped mode. 

           Otherwise, a bus master driver can be used, and the I/O address
           range and the memory map address range previously configured will
           be removed.
 
 
 Installation Problems
 =====================
 Since PCI computers feature Plug-and-Play configuration of PCI adapters,
 conflicts with other adapters are not possible.  If HPVGSET could not
 recognize the HP DeskDirect LAN Adapter, the most likely problem is the
 adapter is not correctly seated in a PCI slot.
 
    PCI slots are usually white and shorter than ISA or EISA slots.  PCI
    adapters have their components on the side of the adapter opposite to
    that of ISA or EISA adapters.  Ensure the adapter is fully seated in
    the PCI slot by pushing the adapter straight into the slot.
 
 On some computers the motherboard can be configured to enable or disable
 PCI slots.  Follow the computer's documentation to ensure that the PCI
 slots are enabled.
