    TITLE:  Ascentia M, MS Windows NT, 3Com 3C575A

    ISSUE

       The 3Com 3C575A CardBus 10/100 Ethernet PC Card may not function
       properly when installed in an Ascentia M that is running Windows
       NT 4.0.

       This issue affects all Ascentia M systems.

    BACKGROUND

       The Ascentia M system uses the TI PCI1131 CardBus controller.
       Windows NT 4.0 does not provide support for CardBus at this time.
       Ascentia M systems that ship with Windows NT 4.0 include
       SystemSoft CardWizard to provide PC Card support under Windows NT
       4.0. The 3Com 3C575A CardBus card will function on the Ascentia M
       under Windows NT after applying a registry fix.

    ACTION

       To resolve the issue, perform the following steps:

       1. Download the file 3C575.REG from one of AST's On-Line!
          forums as follows:

          on your hard drive, copy the downloaded file to that
          directory, and run the file.

       2. Copy the file to a temporary folder on the hard drive.

       3. Open a command prompt, change to the folder where the
          file is located and run:

                REGEDIT -I 3C575.REG

       4. Reboot the system for the changes to take effect.
