    TITLE:  Manhattan P and Madge Token Ring Card

    ISSUE

       When configuring a Manhattan P server with an EISA Madge Token
       Ring card and devices off both NCR SCSI channels, a SCSI bus
       reset error may occur after loading the MADGEODI.LAN driver,
       version 5.09, for Novell 3.12. This error has only been seen
       while using devices off both SCSI channels.

       This issue affects the following systems: 501502, 501503, and
       501830.

    BACKGROUND

       This issue was reported after a customer upgraded the Madge Token
       Ring drivers from the SMART386.LAN, version 5.15, to the new
       MADGEODI.LAN, version 5.09. As soon as the Madge driver was
       loaded, the system generated a SCSI bus reset error and continued
       posting. This seemed to be an informative error that did not
       affect system performance or functionality.

    ACTION

       To resolve the issue, change the secondary SCSI port address from
       the default 0900h - 9ffh to 0f400h - 0f4ffh using the following
       steps:

       1. Boot the computer from the EISA configuration
          diskette.

       2. From the opening screen, press the [Enter] key.

       3. On the welcoming screen, press the [Enter] key.

       4. Arrow-down to Configure Computer and press the
          [Enter] key.

       5. Arrow-down to View and Edit Details and press
          the [Enter] key.

       6. Arrow-down to the second embedded - PCI SCSI
          Controller field and press the [F6] key for edit
          resources.

       7. Move down to the port address field and press the [-]
          key until the address shown is 0f400h - 0f4ffh.

       8. Press the [F10] key when done.

       9. Press the [F10] key again.

       10. Arrow-down to Save and Exit and press the [Enter]
           key.

       11. Highlight the Save Configuration and Restart the
           Computer field and press the [Enter] key.

       12. The configuration has been saved. Press the [Enter]
           key to reboot.
