    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.
