    AST RESEARCH, INC.        TECHNICAL BULLETIN # 1528          7-12-96

    TITLE: Manhattan P and V, Video, OS/2 Warp v3.0

    SUMMARY

       Under OS/2 Warp 3.0, 1024x768 is not an available video resolution
       on the Manhattan P and V systems.

       This issue applies to all Manhattan P and V systems.

    ISSUE

       When attempting to change the video resolution under IBM OS/2
       Warp 3.0, 1024x768 is not listed as an available video resolution
       on the Manhattan P and V systems.

    BACKGROUND

       IBM OS/2 Warp 3.0 does not support 1024 x 768 with less than 1MB
       of video RAM using the Cirrus Logic 5424 chipset.  The Manhattan
       P and V systems contain 512KB of video RAM which is not upgradeable.

    ACTION

       If the user requires resolution 1024x768, the user should add a
       video card that has 1MB or more of video RAM.

    NOTES

       Cirrus Logic video drivers are not shipped with the Manhattan P
       and V systems.

       AST's Cirrus Logic drivers, version 1.01, do not contain drivers
       for OS/2 Warp 3.0.  Video drivers for OS/2 Warp 3.0 were
       incorporated into the Operating System by IBM and Cirrus Logic.
