AST RESEARCH, INC.        TECHNICAL BULLETIN # 1581          09/17/96 
 
 
 
TITLE:  Cabletron E2219 and Bravo MS Pentium
 
 
SUMMARY 
 
   When installing a Cabletron E2219 (9000839) ethernet NIC card in a 
   Bravo MS Pentium system, the user may be unable to attach to the 
   server.
   
   This issue affects the following systems: 501533, 501534, 501651, 
   501660, 501701, 501702, 501703, and 501754.    


ISSUE 
 
   The Windows NT 3.51 driver does not load when the Cabletron 
   ethernet NIC card is installed in the Bravo MS Pentium systems.    

 
BACKGROUND 
 
   The default setting of this card (I/O 300 + 280, IRQ 5 and DMA 3) 
   is not compatible with the Bravo MS Pentium systems. The card can 
   be reconfigured using the Cabletron QUICKSET configuration utility,
   but the Plug-and-Play BIOS restores the default settings on reboot.    

 
ACTION 
 
   Use ICU to store the required Cabletron settings as Extended 
   System Configuration Data in NVRAM.
   The Bravo Plug-and-Play BIOS will read this configuration data 
   and initialize the card with it each time the system is booted. 
   Since ICU is a DOS program, the system will need a small DOS 
   partition in order to boot DOS and run ICU.
   
   Ensure that the power to the system is turned OFF before 
   disconnecting or attaching any peripherals to the system.
   
   Use the following procedure to install the Cabletron card: 
   --------------------------------------------------------- 
   If the Cabletron card is installed in the system, remove it. Boot 
   into the DOS partition on the hard drive.
   Install ICU.
   Reboot DOS allowing the ICU driver to load.
   Turn the system OFF.
   Install the Cabletron card.
   Using QUICKSET.EXE from the Cabletron driver diskette, 
   reconfigure the card with the following parameters:
   
      Primary I/O 380
      Secondary I/O 2A0
      IRQ 10
      DMA 5
   
   Choose Save Configuration when exiting QUICKSET.
   Run the ICU and reconfigure the Cabletron entries with the above settings.
   Select File - Save.
   Exit ICU.
   Reboot system with NT.    

 
NOTES 
 
   See Software Bulletin #0173 for the latest version of ICU.
