    TITLE:  Bravo MS-T and 1540CF Adapters

    SUMMARY

       The floppy drive may fail when multiple Adaptec 1540CF adapters are
       installed in the Bravo MS-T system.

       This issue affects the following systems: 503067
       and 503068.

    ISSUE

       The Bravo MS-T 6180 and 6200 systems generate an

          "Error reading drive A"

       message when multiple Adaptec 1540CF SCSI adapters are present
       in the system.

    BACKGROUND

       According to Adaptec, noise generated on the "DACK2" signal line
       on the 1540CF adapter causes this issue.

    ACTION

       The user must remove one of the 1540 CF adapters, or use a
       different model from Adaptec, such as the 1542CP or 1530P SCSI
       adapters.
