Distorted screen at 640x480 during installation of OS/2 (versions 2.1, Warp 3, Warp4)

[Ingo]

During installation phase of OS/2 while still at VGA resolution the display is terribly distorted. I myself tested with latest Warp4 with all fixes as available from IBM till end 2006 are incorporated. As other users observe thesame, Sasquatch asked me to file a bug report. Thread in the forum is here:

While OS/2 system underneath is (almost) working correctly (if one knows how to operete it blind), the screen is inusable. This I have repeated several times with VBox 2.1.0 and 2.1.2. I do attach a screen shot here which shows more than words.

Once when succeeding to install SciTech SNAP, all is fine and all higher resolutions are available too. Also initial phase of install in real mode and text modes are ok.

If desired, I can supply a CD-image for installation tests which is bootable, contains a Warp4 with all available fixes and updates from IBM even beyond MCP2 (nothing from Serenity). It is compressed some 360MB. I just need information where to upoload, either by mail or in the above thread.
