Under certain environmental conditions, there are design sensitivities in asynchronous clock
VGA text mode diagnostic and stress test applications that use pixel panning can experience
temporary visual anomalies under certain memory configurations. The memory configurations
affected are 64-MB technology products that use 2-KB and 4-KB page sizes.
Entire scanlines will appear to flicker in some VGA diagnostic and stress test applications.
However, there are no known customer sightings of this erratum. No known end-user applications
fail for this erratum.
Test applications using a single VGA font table with a 32-KB font buffer range could
fail. This failure was seen in a diagnostic utility.
Test applications using multiple VGA font tables could fail if the first two fonts are from
different tables. This failing condition can occur in any memory configuration. This
failure was seen in a stress test utility.
