      PicPort driver installation notes for Windows 2000
****************************************************************

----------------------------------------------------------------
General notes
----------------------------------------------------------------
. Files needed to install the PicPort driver.
  The following files must be present and located in the same
  directory:
       - LVPPX.SYS
       - LVPPXW2K.INF

. Location of the PicPort INF file
  - You can download from the Leutron Vision web site only the
    updated INF file. Copy the downloaded files in a local
    directory and give this path to the device manager when
    prompted for driver update.
  - You can install the LVSDS 1.91 version before actually install
    the PicPort board.
    The driver files are installed in:
           <LVSDS>\DRIVERS\WIN2000
    Specify this directory when prompted by the device manager for
    driver installation or update.
  - In the LVSDS CD
           <CD_DRIVE>:\DRIVERS\WIN2000

----------------------------------------------------------------
First time installation
----------------------------------------------------------------
For first time installation of PicPort boards, the system will
ask on startup the driver for the newly found Multimedia device.
Enter the path to the LVPPXW2K.INF file.
The system does not require to be rebooted.


----------------------------------------------------------------
Upgrading from pre-1.91 LVSDS releases
----------------------------------------------------------------
If a PicPort board was already installed in the system using
pre-1.91 LVSDS, the system does not ask for new driver to be
installed, so the update must be forced manually.
LVSDS releases before 1.91 were installing a legacy kernel
mode driver for PicPort boards.
To fix problems with the ACPI HAL, the LVSDS release 1.91
provides a WDM driver for PicPort.
This changement makes the old INF file used to install
the pre-1.91 driver obsolete.

To update the PicPort INF file, due to the way Windows 2000
handles the device driver installation, the following steps should
be performed.
  - Search in the WINNT\INF directory all the .inf files containing
    the lines:
            [Manufacturer]
            %LvMfg%=Leutron
    Usually, they are named OEMxx.INF, where xx is an ordinal number.
  - Delete the found .INF file and the corresponding .PNF file with
    the same name.
  - Start the Device Manager, select the Leutron Vision PicPort device,
    open the Properties dialog and click on Update Driver. Specify the
    location of the new INF file for PicPort.
  - Reboot the system.
