                        BRAVO/286 WITH 3270 EMULATION SOFTWARE

    Some keyboard keys will not function correctly when running IBM or Attachmate
    3270 emulation software on AST Bravo/286 with NMB keyboard (AST part number
    230098-XXX).

    This issue is resolved by a new keyboard controller (AST part number

    controller is available as a BIOS upgrade kit (AST part number 500740-001).
