WinXP display setting: 800x600, 32 bit color, 60Hz vert. freq., PnP
monitor
WinXP display setting: 800x600, 16 bit color, 60Hz vert. freq., PnP
monitor

These settings worked on both my Althon & PII PC (not included that
mentioned at step 1 because that PC got disk read problem before XP
even started after my failed tests at 29-Nov-05 night).

I haven't tested these settings in ME installation yet because it's
late night now here. At first I thought setting 16 bit color triggered
the result. Later I doubt this "finding" because after step 17. I did
rebooted the PII PC again with NEW 10" MON connected from start to end
of reboot without changing color depth at all and nothing abnormal
appeared in graphics output at all. So I couldn't explain the result of
step 12.

I thought so at first but found 32 bit also worked (described in steps
15-17) later.

Sorry for my poor English (not my mother language). I meant I saw
duplicated & fuzzy ghost images of windows desktop screen overlapping
each other across the screen.
