If you have a VESA local bus video adapter with the Cirrus 5426 chip set, the following two problems may occur:

  • On a fast VESA local bus machine, pixels are inappropriately left on. For example, moving the mouse pointer leaves a trail of pixels.
  • After a warm boot, the standard VGA driver (640 x 480 with 16 colors) is run.


Inappropriate pixel activation is caused by the speed of the machine. This problem also occurs under Windows 3.1 with the same hardware configuration.

The warm boot problem is caused by a timing conflict and does not occur on all configurations.


For the pixel problem you need to either slow down the processor speed of your machine or obtain a new video adapter.

If you cold boot your machine, the video driver problem does not occur.
