    TITLE:  Ascentia P Can Only Report 32MB Memory

    SUMMARY

       The Ascentia P only reports a total of 32MB of memory when it
       should report 40MB.

       This issue affects all the Ascentia P systems using third party
       memory.

    ISSUE

       After adding two non-AST 16MB memory modules, the Ascentia P only
       reports a total of 32MB of memory when it should report 40MB.

    BACKGROUND

       The Ascentia P mobile computer comes with 8MB of system memory
       and can be expanded to a maximum of 40MB.

       The Ascentia P uses only EDO (Extended Data Out) single bank
       memory. Some third party memory manufacturers have sold dual bank
       EDO memory for the Ascentia P.
       If dual bank memory is used, the 8MB of memory that are
       pre-installed on the system board may not function as designed
       and the system will only report 32MB of memory instead of the
       full 40MB.

    ACTION

       Please call the memory manufacturer for replacement.
