                           BRAVO/386SX AND KEYBOARD ERRORS

    When using the Bravo/386SX in various software environments, keyboard errors
    may occur.  For example, when using IBM's Attachment 3270 emulation software,
    the left-hand control key does not function at all.  In Lotus and SCO UNIX,
    the function 5 key generates erroneous characters.  In Novell environments,
    the down arrow cursor key will act as a shift-lock or will not function at
    all.

    To resolve these problems, replace the existing keyboard with an NMB keyboard
