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.

   To resolve the issue, perform the following steps: 
     
   1. Download the file 3C575.REG from one of AST's On-Line!

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

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