    TITLE:  NT Hangs w/Adaptec 2940 During Install

    ISSUE

       When Installing Windows NT, version 3.51, on a Manhattan S
       server, the user may find that after selecting the adapter driver
       for the Adaptec board, the system hangs and the display goes
       blank.

       This issue affects all Manhattan S6200 and Commerce Pro systems.

    BACKGROUND

       N/A

    ACTION

       Perform a low-level format of the drive prior to installing
       Windows NT, otherwise the drive may contain an invalid Master
       Boot Record from a previously installed operating system.

       Refer to the Adaptec 2940 user's manual for instructions on
       low-level formatting.
