                 Device Driver Installation Guide

1. Release note
   This software package release is version 1.0, which supports
   USB-to-IDE controllers compliant to "Universal Serial Bus Mass
   Storage Class-Bulk Only Transport" specification Revision 1.0,
   and some legacy one such as In-System USS725. The driver
   currently can read and write ATA devices, such as hard disk,
   Disk-On-Module (DOM), and SanDisk, through the USB-to-IDE
   interface; but not ATAPI devices, such as CD-ROM.

   The driver operates on any Windows CE X86-based platform using
   VIA's chipsets or network controllers. It works properly with
   Microsoft Windows CE 3.00 and it should work for later versions
   of Windows CE.

2. File descriptions
   The package contains 7 files as described below.

3. The following step-by-step instruction assumes your target
   platform is CEPC with the Windows CE 3.00 MAXALL configuration
   adopted. Make sure the USB host controller on the target
   platform is enabled by proper BIOS settings. A USB-to-IDE
   controller, such as a Bulk-Only-Transport-compliant one
   like Cypress EZ-USB chip or In-Systems USS725, is needed
   for an initial evaluation of the driver.

4. Make a binary image
   Refer to "VIA WCE X86 Driver Installation Migration Guide for
   Microsoft Windows CE Platform Builder 3.00 & Add-on Pack" and
   "VIA WCE X86 USB UHCI Driver Installation Guide" to complete
   a binary image. Download it to your target platform and verify
   the USB UHCI driver works properly. Note, however, this storage
   driver is independent of the underlying USB host controller type.

5. Copy files to the current release directory
   For a retail build, copy the following file:
      USBATA.DLL

   For a debug build, copy the following three files:
      USBATA.DLL
      USBATA.PDB
      USBATA.MAP

6. Modify bib file in the current release directory
   Locate the Platform.bib file and add the following lines:

      IF CEPC_USBATA
         USBATA.DLL     $(_FLATRELEASEDIR)\USBATA.DLL        NK  SH
      ENDIF

   A sample Platform.bib file is included for your reference.

7. Modify reg file in the current release directory
   Locate the Platform.reg file and add the following lines:

      IF CEPC_USBATA
      [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1451_512\Default\Default\USS725]
         "DLL"="USBATA.DLL"

      [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\Default\Default\8\USBStorage]
         "DLL"="USBATA.DLL"

      [HKEY_LOCAL_MACHINE\Drivers\USB\USBATA]
         "Folder"="USB_HD"
      ENDIF

   All the above entries are optional. The first four provide the
   plug & play ID's to load the storage driver. If not given,
   the system will prompt the user asking for the driver name.
   If the last two are not given, the folder name by default will
   be "Storage Card"; you may modify it to suit your needs.

   A sample Platform.reg file is included for your reference.

8. Add the environment variable
   Choose Settings from the Platform menu in PB3.00. Select the
   Environment to define CEPC_USBATA and set the value to 1
   as below.

      set CEPC_USBATA=1

9. Choose "Make Image" from the Build menu to make a new OS image
   to include the USB storage device driver. Then download the
   image to your target platform.

10. Basic testing
  (1) Installation
      Execute "Windows Explorer" and verify the existence
      of the "USB_HD" file folder.
  (2) Directory creation/rename/deletion
      Use the Explorer to create and rename and delete folders
      under directory USB_HD.
  (3) File read/write/deletion
      Use the Explorer to copy and rename and delete several
      files under directory USB_HD. View the details of them
      and verify the size and type and date of the duplicated
      are identical to the original.

11. Trouble shooting
    In case you encounter any problem, first connect the debug
    port on your target Windows CE platform to your PC-based NT
    development platform. Make a debug build binary image and
    download it to your target platform. Dump related debug
    messages and then contact VIA's representatives for further
    technical assistance.

12. Quality assurance
    The software package has been tested by the RWTEST program,
    shipped along with Windows CE 3.00. The RWTEST program performs
    stress tests for disk reads and writes. This release passed all
    the tests.
