    AST RESEARCH, INC.         TECHNICAL BULLETIN #0803                 12-30-92

                      EISA SYSTEMS WITH THE RACAL INTERLAN CARD

    PROBLEM:       The drivers shipped with the RACAL Interlan card, used in the
                   AST SE system and sold as an option kit for other EISA
                   systems, do not support either PBurst or ODI capability.  The
                   Burst Mode protocol is a new technology for expediting large
                   file reads and writes over wide area network links.  The ODI
                   protocol allows multiple protocols to link to one card,
                   (i.e., IPX and TCP-IP).

    CAUSE:         The advanced PBurst and ODI capabilities of the RACAL card not
                   supported by the drivers that were supplied by RACAL and
                   originally shipped with AST systems up to 12-18-92.

    AFFECTED
    SYSTEMS:       Any system using a RACAL Interlan adapter AST part number
                   500875-001 or 230214-001.

    SOLUTION:      Obtain the diskette of drivers released on 12-18-92 using AST
                   part number 910462-004 release 1.02 from RACAL.
